ActionTag is an easy way to embed forms on any site. Much like Twitter Embedded Timelines, the idea is to use one line of JavaScript and one line of HTML to have a foolproof way to present a form that posts back to your database. Substantive changes to the API are documented in the Changelog.

What is it?

ActionTag is our name for our embeddable forms functionality. Embeddable on any page on the web, it will:

• Make an API call to retrieve that form’s definition (aka which fields should display)
• Render a fully functional form to the screen
• Pre-fill that form under certain circumstances
• Handle submission of that form back to the server
• Deal with behaviors that occur after submission such as:
  • Displaying another form (secondary ask, or daisy-chaining)
  • Showing a thank you message
  • Redirect to another URL

How to Find the Embed Code

The easiest way to use ActionTag on your own website is to use the embed codes provided inside the form builder. In Online Actions there is a “Link & Embed” button at the top of every step of the form builder, which is enabled once you have published your form. In EveryAction 7, you can find the embed code on the last step of the Online Page Manager (the step labeled “Published Page Info”).

Getting Started with Manually Embedding a Form

All that’s necessary to use ActionTag is to drop a special <div> tag on any page along with our JavaScript file. For example:

  <script type="text/javascript" src="https://d1aqhv4sn5kxtx.cloudfront.net/actiontag/at.js"></script>
  <div class="ngp-form" data-form-url="https://actions.everyaction.com/v1/Forms/5r7I2eqN-kyshSYk6ZS6Rg2"></div>

We use the class ngp-form to indicate that this is the place where the form should render.

NOTE: any use of ActionTag for processing payment information must be embedded in a TLS-secured page.

To specify which form to render, add the only other required data attribute, the data-form-url attribute, e.g. data-form-url="https://actions.everyaction.com/v1/Forms/5r7I2eqN-kyshSYk6ZS6Rg2". Each form published has a unique id which can be used in this tag.

These are the simplest cases. Below are some more of the data attributes that can optionally be added to the tag to alter its behavior.

SmartLinks

For users who draft emails for use in Targeted Email, a special merge field is available which auto-fills user contact data merge fields in an ActionTag form. To use this merge field, append contactdata={{ContactData}} to any URL which hosts an ActionTag form, and embed the resulting URL in the body of a Targeted Email. Doing so will cause the following merge data to be automatically merged in to when email receipients click through the URL in the email, and view the form:

• First Name
• Middle Name
• Last name
• Subscriber Email
• Street Address
• City
• State or Province
• Zip or Postal
• Home Phone
• Cell Phone
• Work Phone
• Employer
• Occupation
• Prefix
• Suffix

Example

1. You create a form in Online Actions, and use ActionTag to embed it at https://www.peopleforgood.com/donate.
2. You draft an email to your supporters.
3. In the body of the email, you include the following URL: https://www.peopleforgood.com/donate?contactdata={{ContactData}}
4. You paste the body of the email into Targeted Email, and send the email to your supporters.
5. When Targeted Email generates the email, it prepares a special encoded string, specific to each supporter. This encoded string is merged in to the personalized email which each supporter receives. For example, supporter Jane Casey might receive an email with the URL https://www.peopleforgood.com/donate?contactdata=1234ABC.
6. Jane Casey, one of your supporters, receives the email and clicks the link.
7. ActionTag displays the form from step 1.
8. ActionTag reads the contactdata string, and merges Jane Casey’s data into the form display.

It is also possible to add contactdata alongside other parameters. For example, if you wanted to use the Targeted Email merge field for a record’s highest previous contribution to set the contribution amount on a form, defaulting to $3 if the record is a nondonor, then the url would look like this: https://www.peopleforgood.com/donate?am={{HighestPreviousContribution or '3'}}&contactData={{ContactData}}.

What are Query Strings?

A query string is something you can add to the end of the URL your form lives at, e.g. www.example.com/formid?foo=bar Primarily, query string values are used to pre-fill values in the form. The general format is that the first bit is the name of the form field, followed by an equals sign and then whatever data you wish to pre-fill that form field with. ActionTag assumes US formats for all fields (phone, postal code, amounts, etc.).

The way to add these onto a form is that the first one needs to use a question mark, and other subsequent ones use an ampersand, e.g. www.someurl.com/formid?sourceid=12345&ms=top-nav

Query Strings

The following are available visible fields to be filled via Query Strings:

Name	Parameter	Sample	Notes
AddressLine1	add1	add1=1250+Hancock+St.
AddressLine2	add2	add2=Ste.+202
Additional Contribution Value	AdditionalContributionValue	AdditionalContributionValue=25	Prefill the additional contribution amount on event forms only
Amount	am	am=5	This sets the default amount on a contribution form.
Amount Options	amtOpts	amtOpts=3,5,20.16,50,100	This sets the amount button options on a contribution form. To select a particular contribution amount upon loading the form, use the ‘am’ query string.
City	ci	ci=Boston
Cover Costs	CoverCosts	CoverCosts=true	If the Cover Costs checkbox is enabled on the Contribution or Ticketed Event form, this query string checks that checkbox, adding the Cover Costs amount (configured in Online Actions) to the contribution amount selected by the donor.
Currency	currency	currency=EUR	Works for Contribution forms that support international currencies; will not work for Ticketed Event forms • Valid values include USD, GBP, CAD, and EUR • Can be used in combination with am and amtOpts • If currency is passed without am or amtOpts, passed currency will be selected and amounts on form will be converted • If currency is passed with amtOpts, passed currency will be selected and amount options will be offered as passed • If supporter then selects a new currency, amounts will be converted to selected currency • If currency is passed with am, passed currency and amount will be selected

There are also elements that may not be visible, but have to do with how the form submission data is entered into the database:

Name	Parameter	Sample	Notes
Attributed Contact ID	attr	attr=109418764	The contribution or event signup will have the specified contact attribution (if applied to the submission of a Contribution or Event form). The contact ID should be the VANID for an Online Actions form, or the NGP ID for a version 7 form. Since a single contribution can have more than one contact attribution, you may use a comma delimited list of IDs to attribute the contribution to more than one contact, i.e. attr=109418764,109419268
Host Committee	ac	ac=VN96C3TBX36	The contribution or event signup will have the specified contact attribution (if applied to the submission of a Contribution or Event form). The contact ID should be the VANID for an Online Actions form, or the NGP ID for a version 7 form. Additionally, the ac query string will prefill the Host Committee member selection on the published form (if the query string value matches that of a Host Committee member configured for the Event).
Kiosk Mode	kiosk	kiosk=true	Using this query string parameter disables FastAction and ActionProfile integration. This is useful if the user is using a form on a tablet or laptop in a public place and do not want the submission information remembered on that device. Notably, if you configure one form to redirect to another form (what we refer to as secondary ask), the form fields on the second fom will not be pre-populated by the submission info from the first form. If you are launching the form with knowledge of who a contact is, kiosk mode does still allow you to prefill form fields using other query string values, e.g. fn=Michelle as documented above.
MarketSource	ms	ms=201409_fb_birthday_v1	Can be used to track different ad buys to the same form to compare ROI
Source Code Name	source	source=W213appeal	Overrides the form default. Matches source code by name, or if it doesn’t exist, creates a new source code. Valid characters include letters, numbers, hyphens, and underscores. Max length of 50, any characters beyond that will be truncated.
Source Code ID	sourceid	sourceid=57	Overrides the form default. Uses the source code ID, not the name, for matching to existing source codes, cannot create new source codes via this method.
QuickSign	quick	quick=true	Automatically submits the form and segues to the next action (thanks page, secondary ask, or an arbitrary other URL) if all the required fields are prefilled by either a query string value or ActionProfiles. This does not work for contribution or event forms.
Social Network Referral	snw	snw=1 Facebook snw=2 Twitter	Indicates whether the user was referred to the form from Facebook or Twitter.

Hidden Metadata Fields

Hidden Metadata Fields can be used to capture metadata about the form submission, such as the URL referrer or supporter’s affiliate ID. These inputs do not display on the supporter-facing form.

Creating Hidden Metadata Fields

You can create Hidden Metadata Fields in Online Actions on the Settings tab. There, you can define the Identifier, Display Name, and Description. Note that the Identifier is an alphanumeric value that always starts with “oa_”, cannot contain any spaces, and is case-insensitive.

Once created, the hidden input is available on every form without the need to republish.

Populating Hidden Metadata Fields

There are two ways to populate Hidden Metadata Fields: query strings and JavaScript.

A query string is ideal when the same value should be applied to all supporters coming from the same link, such as from an email or ad. To populate a Hidden Metadata Field using a query string, use the Identifier as the “name” portion of the name-value pair. Example: ?oa_email_send_date=2021-02-02

JavaScript allows you to add your own logic to collect information about a supporter’s browser session and is a better fit when an Identifier’s value is likely to be different from one supporter to the next. To populate a Hidden Metadata Field using JavaScript, we recommend using ActionTag’s alterPost callback to populate that field’s Identifier. View this alterPost callback example to populate an oa_visitor_id Hidden Metadata Field.

Using Google Remarketing Codes

In order to use Google remarketing codes, you have to call them to load AFTER the form has loaded.

Here’s an example of what Google will give you as a remarketing code:

<!-- Remarketing tags may not be associated with personally identifiable information or placed on pages related to sensitive categories. For instructions on adding this tag and more information on the above requirements, read the setup guide: google.com/ads/remarketingsetup -->
<script type = "text/javascript">
    /*  <![CDATA[ */
    var google_conversion_id = 985021774; <!-- this will vary by client -->
var google_conversion_label = "lXkMCIq98gYQzvrY1QM"; <!-- this will vary by client -->
var google_custom_params = window.google_tag_params;
var google_remarketing_only = true;
/* ]]> */
</script>
<script type="text/javascript" src="https://www.googleadservices.com/pagead/conversion.js">
</script>
<noscript>
  <div style="display:inline;">
    <img height="1" width="1" style="border-style:none;" alt=""
      src="https://googleads.g.doubleclick.net/pagead/viewthroughconversion/985021774/?value=0&label=lXkMCIq98gYQzvrY1QM&guid=ON&script=0" />
  </div>
</noscript>

Notice that the conversion ID and conversion labels are in two places. First in the regular javascript and second inside the <noscript> code block. These are the values you need to copy into the new code snippet.

Here’s the new code you need to use, make sure to grab the conversion ID and label from the code Google provided, and insert them below. Once you’ve updated this snippet with your account information, you can copy it and paste it into the source of the form by clicking the “source” button and paste.

<script type="text/javascript">
    var img = document.createElement("img");
    var trackUrl = "https://googleads.g.doubleclick.net/pagead/viewthroughconversion/985021774/?value=0&label=lXkMCIq98gYQzvrY1QM&guid=ON&script=0"; <!-- change ID (985021774) and label (lXkMCIq98gYQzvrY1QM) in this line -->
    img.src = trackUrl;
    document.body.appendChild(img);
</script>
<noscript>
    <div style="display:inline;">
        <img height="1" width="1" style="border-style:none;" alt=""
          src="https://googleads.g.doubleclick.net/pagead/viewthroughconversion/985021774/?value=0&label=lXkMCIq98gYQzvrY1QM&guid=ON&script=0" />
        <!-- change ID (985021774) and label (lXkMCIq98gYQzvrY1QM) in this line -->
    </div>
</noscript>

Notes for website builder products

Using ActionTag with a website builder product like Squarespace or Wix comes with a few challenges. While we can’t support other applications, here are a few pointers we’ve learned over the years from various clients’ experiences:

• Squarespace will not consistently render ActionTag forms if using Ajax page load. We’ve been told you can turn this setting off by going to /config/design/styles inside the settings for your Squarespace site.
• Wix can take the embed code using their html iframe widget, but please note, this will end up iframing the form into your site, and may cause scrollbars, plus your ability to redirect to an external URL will be limited.

Data attributes on the ActionTag div are the way to pass certain data or instructions to ActionTag to influence its behavior.

Since these attributes are part of the div, any CMS or website system can easily write code that will consume ActionTag with the characteristics they desire. This is the way we have written our own Drupal modules in-house.

What follows are the data attributes we currently support:

data-form-url (required)

It is used to specify the url from which the form definition is retrieved. Only required if data-id is not used, or if presenting an advocacy related form, which requires getting the form definition from a different endpoint. Example, to load a form from a url:

<div class="ngp-form" data-form-url="https://actions.everyaction.com/v1/Forms/5r7I2eqN-kyshSYk6ZS6Rg2"></div>

For advocacy related forms, you have to request the form definition through our advocacy service, which we creatively call advocator. This url is constructed using the following pattern:

• Advocacy form proxy url, e.g. https://advocator.ngpvan.com
• The URL encoded database API endpoint, meaning take the endpoint https://actions.everyaction.com/v1/Forms/ and represent it like this: https%3A%2F%2Factions.everyaction.com%2Fv1%2FForms%2F
• the form ID, e.g. ntieGYzrK0meNMqRibRbAw2
• and finally the string ngpForm at the end

Complete example for an advocacy related form, where we grab the form definition from the advocacy endpoint, with the rest of the form ID URL encoded after:

<div class="ngp-form" data-form-url="https://advocator.ngpvan.com/https%3a%2f%2fsecure.everyaction.com%2fv1%2fForms%2fntieGYzrK0meNMqRibRbAw2/ngpForm"></div>
``

data-id (required for legacy implementations)

It is used to specify the id of the form to render. Only required if data-form-url is not used. Please note: that some form IDs start with a minus sign (-), as shown in the example above. Do not delete this as it is a part of the form ID. Note that an advocacy-related form must use the data-form-url attribute instead. Example, to load a non-advocacy-related form with id 12345:

<div class="ngp-form" data-id="12345"></div>

data-databag

(optional) - Used to specify whether to use ActionProfiles to fill the form fields. In order for this functionality to work, please contact support if you are interested in getting your URL(s) added to the allowed domains list.

Note: databag is the legacy name for ActionProfile, hence the attribute/name mismatch.

• Default: nobody
• Options:
  • nobody - disable this functionality
  • everybody - Allow pre-filling of information from any site in the ActionProfile network. Also requires sharing pre-fill data with other sites in the network.

Example, to enable the ActionProfile filling (assuming the site on which this tag is sitting has been allowed):

 <div class="ngp-form" data-id="12345" data-databag="everybody"></div>

data-endpoint

(optional)- Used in conjunction with data-id to specify a non-default API endpoint for retrieving the form definition and submitting the resulting data. This is used mostly for hitting development servers; though, if you are using data-form-url you do not need this. If you are using data-id, and your database instance is accessed by a URL other than www2.myngp.com, that is you likely need to use this attribute.

• Default: https://api.myngp.com

Example, to load the definition and submit to http://developerboxname.local

<div class="ngp-form" data-id="12345" data-endpoint="http://developerboxname.local"></div>

data-formdef-endpoint

(optional) - This attribute defines a different read endpoint from the POST endpoint defined above. This can be useful when you don’t need to personalize the form definition on a per-supporter basis and anticipate an extremely high load scenario. One could call an external cached version of the response, either from a CDN, or even flat file store like Amazon S3.

• Default: value of data-endpoint attribute.

Example, to read the form definition from Amazon S3 instead of the NGP API servers:

<div class="ngp-form" data-id="12345" data-formdef-endpoint="https://formdefs.s3.amazonaws.com/api.myngp.com"></div>

data-labels

(optional)- Only available for signup forms. Used to specify the placement of the labels when the form is rendered. In general, this is discouraged, but it is available for minimal presentations for quick email signup forms.

• Default: above
• Options:
  • inline - sets the labels as the HTML5 placeholder attribute on the input.
  • above - displays form labels above the form fields with a tag

Note, the rationale here is that, while labels being above or beside the input can be altered with CSS, making them appear as placeholders is more complicated.

Example, to have labels appear as placeholders:

<div class="ngp-form" data-id="12345" data-labels="inline"></div>

data-mobile-autofocus

(optional)- Used to specify whether the form should scroll to the form content on page load. Forms hosted by Online Actions have this parameter set to true. If you embed the form without this attribute, those will load as if you had specified it to be false.

• Default: false
• Options:
  • true - after the form loads on mobile devices, the form will scroll such that the form content is within the viewport.
  • false - no scroll will happen on form load.

Example:

<div class="ngp-form" data-id="12345" data-mobile-autofocus="true"></div>

data-resource-path

(optional) - Used to specify location of ActionTag resources such as actiontag.min.css. Primarily used for internal development purposes.

• Default: https://d1aqhv4sn5kxtx.cloudfront.net

Example, to use /sites/xyz/libraries/actiontag:

<div class="ngp-form" data-id="12345" data-resource-path="/sites/xyz/libraries/actiontag"></div>

Overview & Intended Audience

Callbacks are a rather technical feature set, and are not needed for the vast majority of uses of ActionTag. The callbacks described below are powerful, but also probably require some experience doing web development, and are not needed for most uses of ActionTag. Feel free to skip the rest of these docs unless you are a developer.

We have a series of callbacks in ActionTag which allow developers to alter bits of functionality. In order for ActionTag to know about your callback, we have a simple registration process.

First create the global JavaScript variable nvtag_callbacks (but only if it doesn’t already exist). The following snippet accomplishes this:

var nvtag_callbacks = nvtag_callbacks || {};

If your code is within a closure, you will need to explicitly ensure it is declared in the global namespace so ActionTag can find and reference it. Here that’s done with a local reference so that we no longer have to reference it by calling window.nvtag_callbacks:

window.nvtag_callbacks = window.nvtag_callbacks || {};
var nvtag_callbacks = window.nvtag_callbacks;

The last bit is callback specific. Perhaps you want to add a postRender callback to do something after the ActionTag form has been rendered.

1. Instantiate that callback as an array if it doesn’t yet exist
2. Create the actual callback function. The arguments to your function are the callback arguments listed below
   • Note, the first argument to a callback is always the name of that callback. This is done in an attempt to allow one function to be registered from multiple callbacks and then allow that function to handle things internally.

3. Push your callback onto the postRender callback array

   nvtag_callbacks.postRender = nvtag_callbacks.postRender || [];
   // This function can be called anything, we don't care
   var sampleCallback = function() {
    alert("The form has been rendered!");
   }
   nvtag_callbacks.postRender.push(sampleCallback);
   

   Now your callback code will be called by the ActionTag at the time that postRender should happen! (which is after rendering of the form is complete).

Putting it all together:

var sampleCallback = function() {
  alert("The form has been rendered!");
}
var nvtag_callbacks = nvtag_callbacks || {};
nvtag_callbacks.postRender = nvtag_callbacks.postRender || [];
nvtag_callbacks.postRender.push(sampleCallback);

At the right time in the ActionTag process, we will iterate over each of the callbacks in that array and call them.

Technical background

We use our callbacks syntax to put it into the global namespace because ActionTag loads asynchronously. Also, we wish to support multiple callback sources, hence the instructions to not redeclare it over and over again.

A warning on the power of these abilities

Since our callbacks allow you to alter internals of our system, it is possible to make quite a mess of things, sometimes even in potentially dangerous/breaking ways. With great power comes great responsibility. For example, using the alterFormDefinition() callback:

var alterFormDefinition = function(args) {
  // This will blank out the form_elements array thereby effectively
  // breaking this form definition!
  args.form_definition.form_elements = [];
  return args;
};

So always test your callbacks carefully on a page before putting them live.

A note on the examples below

For the examples given below with each callback we are omitting the following bit:

var nvtag_callbacks = nvtag_callbacks || {};
nvtag_callbacks.postRender = nvtag_callbacks.postRender || [];
nvtag_callbacks.postRender.push(sampleCallback);

Note that this must happen for each callback in order for them to be registered and called by ActionTag.

alterErrors

alterErrors (args)

args is a dictionary with the following keys:

• val - The current value of this field
• field_name - The name of this field
• require_valid - Errors, if any.
• def - This element’s definition.

This callback is called when checking the error state of a field. It allows you to intercept the error and alter it.

An error should take one of the 2 following states:

• false - There is no error
• string - Text description of error

alterErrors example

alterFill

alterFill(args)

args is a dictionary with the following keys:

• fill_dict - The fill dictionary. Key/value pairs.
• fill_source - None, BrowserDatabag, PreviousFormState, RecipientDatabag, or QueryString.

This callback is called after the form has completed rendering but before it is filled allowing you to intercept and alter the values which are pre-filled on the form.

Note: In order for this callback to work properly, you must return the args dictionary with your modified form_definition.

alterFormDefinition

alterFormDefinition(args)

args is a dictionary with the following keys:

• form_definition - The form’s definition, which we define as the JSON blob that composes what the form should look like.

This callback is called anytime the application requests the form definition. This is used throughout the system, both for rendering and for many other mechanics.

Note: In order for this callback to work properly, you must return the args dictionary with your modified form_definition.

Example usage

alterPost

alterPost(args)

args is a dictionary with the following keys:

• data - The form state / user data.
• url - The URL to which the data will be posted.
• form_id - The public ID of the form.
• form_definition - The form definition.

This callback is called before POSTing data. It is used to alter the data that will be POSTed.

Note that only fields which already exist on the form may be modified during alterPost. It is not possible to add new fields to the form submission in this callback.

alterRequireValid

alterRequireValid(args)

args is a dictionary with the following keys:

• val - The current value of this field
• field_name - The name of this field
• require_valid - boolean, true if required, false if not.
• form_def - The form definition.

This callback is called when determining if a field is required for the form to validate.

onSubmit

onSubmit(args)

This callback is called when a form is submitted.

args is an empty dictionary.

postContributionAmountChanged

postContributionAmountChanged(args)

args is a dictionary with the following keys:

• view - The ActionTag form view
• baseAmount - Base contribution amount, before Cover Costs are applied
• totalAmount - Total contribution amount, after Cover Costs are applied
• coverCost - Cover Costs amount that is being applied to the base contribution amount
• coverCostEnabled - boolean, true if cover costs checkbox is checked

This callback is called when the contribution amount for the form is changed.

postFill

postFill(args)

args is a dictionary with the following keys:

• view - The ActionTag form view
• fill_dict - The fill dictionary. Key/value pairs.
• submit - The function responsible for submitting the form.

This callback is called after the form is filled.

postPaymentMethodChanged

postPaymentMethodChanged(args)

args is a dictionary with the following keys:

• new_payment_method - The payment method selected on the form

This callback is called after a payment method has been chosen. No return value is expected.

postRender

postRender(args)

args is a dictionary with the following keys:

• form_definition - The form definition.
• options - The view’s options.
• thank - boolean, true if this is a thank you message, false if it is not.

This callback is called after the form has completed rendering but before it is filled. Common use cases are to fire JavaScript behaviors that require the form to be present.

var myPostRender = function(args) {
  alert("The form has now been rendered!");
  return args;
};

Note, multiple things induce the rendering of a form so this will likely be called multiple times. Ensure any code that depends on postRender() is tolerant of that.

Optionally receive the view and alter any options or override any methods on it:

var myPostRender = function(args) {
    console.log(args.form_definition);
    return args;
}

preSegue

preSegue(args)

args is a dictionary with the following keys:

• submitted_values - The values which were submitted across the network
• response - The response from the server to that submission

This hook is called after a successful form submission, but prior to the segue to the next thing.

As a quick primer, there are, at current, 3 different things which can happen after a successful form submission:

• Display a thank you message
• Display another form (aka Secondary ask)
• Redirect to another page anywhere on the internet

preSegue() happens before the transition to this next step so it’s useful for intercepting it and altering the behavior based on the submitted values and/or the response from the server.

segue

segue(args)

args is a dictionary with the following keys:

• formviews - The form views in question
• thank - boolean, true if this is a thank you message, false if it is not.
• calling_tag - The view in question.

This hook is called when a segue is happening.

As a quick primer, there are, at current, 3 different things which can happen after a successful form submission:

• Display a thank you message
• Display another form (aka Secondary ask)
• Redirect to another page anywhere on the internet

We call the transition from one thing to another thing a segue. This callback is called when making that transition.

Note, it is NOT called in case 3 above because we have no control over another page on the internet.

Restyle credit card field

Apply custom styling to the credit card iframe fields

Example:

var nvtag_callbacks = window.nvtag_callbacks = window.nvtag_callbacks || {};
nvtag_callbacks.alterFormDefinition= nvtag_callbacks.alterFormDefinition|| [];
nvtag_callbacks.alterFormDefinition.push(function (args) {
  if(args && args.form_definition && args.form_definition.form_elements) {
    var paymentInfo;
    for(var i = 0; i < args.form_definition.form_elements.length; i++){
      var topLevel = args.form_definition.form_elements[i];
      if(topLevel && topLevel.name === 'PaymentInformation'){
        paymentInfo = topLevel;
        break;
      }
    }
    if(paymentInfo && paymentInfo.children){
      var account, cvv, exp;
      for(var j = 0; j < paymentInfo.children.length; j++){
        var child = paymentInfo.children[j];
        if(child && child.name === 'Account'){
          account = child;
        } else if(child && child.name === 'SecurityCode'){
          cvv = child;
        } else if(child && child.name === 'ExpirationMonth') {
          exp = child;
        }
      }

      if(account){
        console.log('updating Account styling');
        account.styles = { color: 'red' }; // add style overrides
      }
      if(cvv){
        console.log('updating SecurityCode styling');
        cvv.styles = { color: 'green' }; // add style overrides
      }
      if(exp){
        console.log('updating Expiration Date styling');
        exp.styles = { color: 'yellow' }; // add style overrides
      }
    }
  }
console.log('alterFormDef', args);
return args;
});

alterErrors

Take the provided error message and adjust it to something else.

Example:

var myAlterErrors = function(args) {
      if (args.field_name === 'FirstName') {
        if (args.errors) {
          args.errors = ["YOU MUST GIVE US YOUR FIRST NAME TO PROCEED"];
        } else {
          if (args.val !== "Frank") {
            args.errors = ["We only accept a first name of Frank"];
          }
        }
      }
      return args;
};

var nvtag_callbacks = nvtag_callbacks || {};
nvtag_callbacks.alterErrors = nvtag_callbacks.alterErrors || [];
nvtag_callbacks.alterErrors.push(myAlterErrors);

alterFormDefinition

Simple

A simple use case is to override some attribute of the definition:

// Implementation of an alterFormDefinition Callback
var alterFormTitle = function(args) {
  // Note, changing this title will not make a visual change unless the title is
  // used in the template which it's not by default in ActionTag.
  args.form_definition.title = "This title has been overridden";
  $('.status').html("<pre>Form Title: " + args.form_definition.title + "</pre>");

  // Must return the altered object so it will be used
  return args;
};

Intermediate

A bit more complex example is to alter something within the form definition. Let’s say you want to change the contents of the Header HTML markup. Note, in this example we are using the Underscore module to iterate over the elements

var changeHeaderHtml = function(args) {
  // args is a dictionary with a key of "form_definition"

  // iterate over each element, 
  _.each(args.form_definition.form_elements, function(child, index) {
      if (child.name === 'HeaderHtml') {
          child.markup = "<p>Replaced Markup</p>";
      }
  });

  return args;
};

Advanced: adding a field

Let’s say you want to add a field to the form definition to be collected:

var addSpouseField = function(args) {
  _.each(args.form_definition.form_elements, function(child) {
      if (child.name === 'ContactInformation') {
          spouse_field = {
              name: 'Spouse',
              title: "What is your spouse's name?",
              type: 'textfield',
              weight: 99, // We want it to appear at the bottom of the fieldset
              queryString: 'sp'
          };
          child.children.push(spouse_field);
      }
  });
  return args;
};

Note, for this case, if Spouse is not in the original form definition, the API would not be able to parse it, so you will need to intercept and store that POST value somewhere else.

Also note that since the added definition has a queryString of 'sp', it will fill if the page has a query string argument like: ?sp=Joe

Rearrange fields

Let’s say we want to rearrange some fields. Or perhaps we want to move some fields into another fieldset. The following example covers that case:

var rearrangeFields = function(args) {
  // First add a new fieldset to hold these fields
  var name_fieldset = {
      name: 'Name',
      title: 'Name',
      type: 'fieldset',
      children: []
  };
  var name_index = args.form_definition.form_elements.push(name_fieldset);
  // Decrement as push returns the length, we want reference to the last element
  name_index--;

  _.each(args.form_definition.form_elements, function(child) {
    if (child.name === 'ContactInformation') {
        _.each(child.children, function(element, key, children) {
            if (element.name === 'FirstName' || element.name === 'LastName') {
                // Add to our new name fieldset
                args.form_definition.form_elements[name_index].children.push(element);

                // Remove from the other fieldset
                children[key] = { 'type': 'hidden'};
            }
        });
        child.title = 'Address';
    }
  });
  return args;
};

In this case we are creating a new fieldset for Name, moving the name fields into that fieldset, removing them from their original fieldset (ContactInformation), and changing the title of the Contact Information fieldset to Address to better indicate its purpose.

Redirect based on recurring or contribution amount values

Perhaps you want to change where a donor goes after form submission in case they choose to give over a certain threshold or choose to give a recurring contributon. Using the preSegue callback you can look at the submitted values and make conditional redirects based on that information. Note, in practice you probably only want to use one of these two conditionals, but both are shown in the same example below for expediency:

var nvtag_callbacks = nvtag_callbacks || {};
nvtag_callbacks.preSegue = nvtag_callbacks.preSegue || [];
nvtag_callbacks.preSegue.push(function submitSegue(args) {
  var contribAmount = parseFloat(args.postVals.Amount);
  var isRecurring = args.postVals.IsRecurring;
  if (isRecurring) {
      window.location = "http://www.yourdomain.org/recurring-thanks-page";
  }
  if (contribAmount > 5000) {
      window.location = "http://www.yourdomain.org/big-spender-thanks-page";
  }
  return args;
});

Obviously, you will want to adjust the threshold for high (or low) dollar conditional redirects, as well as the redirection destination in the above examples.

preSegue

Perhaps you want to track the contribution amount in another analytics package. Here’s how you capture it on form submission:

var contribAmount;
var submitSegue = function (args) {
    contribAmount = args.postVals.Amount;
    console.log(contribAmount);
    return args;
}
var nvtag_callbacks = nvtag_callbacks || {};
nvtag_callbacks.preSegue = nvtag_callbacks.preSegue || [];
nvtag_callbacks.preSegue.push(submitSegue);

You could then call the variable contribAmount to pass off to your analytics service.

Alter country list

If you want to alter the list of countries on your forms, the following example shows you how to remove a country, rename a country, or potentially insert a new option, all using the postRender callback. Note: if adding a new country, make sure you map it back to an existing value so the address is entered to the system in a way we can process

var alterCountries = function(args) {
  // Remove a country by the value in the dropdown
   var removalItem = document.querySelector('select[name=Country] option[value="XK"]');
   removalItem.parentNode.removeChild(removalItem);

  // Rename a country publicly (but will map to the existing value in the database)
  var renamedItem = document.querySelector('select[name=Country] option[value="VI"]');
  // desired new text to display
  renamedItem.innerText = 'US Virgin Islands';

  // Insert a new country (not recommended, only use it to map a new entry to an existing value)
  // replace "Dominican Republic" with the name of country that comes right before the country you wish to add
  var previousCountry = document.querySelector('select[name=Country] option[value="EE"]'); 
  previousCountry.insertAdjacentHTML('afterend','<option value="Essos">Essos</option>');
}
var nvtag_callbacks = nvtag_callbacks || {};
nvtag_callbacks.postRender = nvtag_callbacks.postRender || [];
nvtag_callbacks.postRender.push(alterCountries);

Alter contribution amount options

Removing the default amount

When setting up a Contribution form, you must choose an amount that will be selected by default when a supporter loads the published form. Use this callback if you would prefer that no amount is selected by default on load.

(function() {

    window.nvtag_callbacks = window.nvtag_callbacks || {};
    window.nvtag_callbacks.alterFormDefinition = window.nvtag_callbacks.alterFormDefinition || [];

    function findElementByName(def, name){
        var elements = def.form_elements;
        for(var i = 0; i < elements.length; i++){
            var element = elements[i];
            if(element.name === name){
                return element;
            }
            if(element.children && element.children.length){
                var children = element.children;
                for(var j = 0; j < children.length; j++){
                    var child = children[j];
                    if(child.name === name){
                        return child;
                    }
                }
            }
        }
    }

    function clearDefaultValues(selectAmount){
        if(!selectAmount) return;

        delete selectAmount.default_value;

        if(selectAmount.frequencyOptions){
            for(var i = 0; i < selectAmount.frequencyOptions.length; i++){
                var opt = selectAmount.frequencyOptions[i];
                if(opt && opt.options && opt.options){
                    delete opt.options.default_value;
                }
            }
        }

        if(selectAmount.children){
            for(var i = 0; i < selectAmount.children.length; i++){
                var child = selectAmount.children[i];
                // children of SelectAmount are the currency-specific SelectAmount versions
                // which each have their own frequencyOptions and default values
                clearDefaultValues(child);
            }
        }
    }

    window.nvtag_callbacks.alterFormDefinition.push(function (args){
        var def = args.form_definition;
        if(def.type !== 'ContributionForm') return;

        var selectAmount = findElementByName(def, 'SelectAmount');
        clearDefaultValues(selectAmount);

    });

})();

Note, this callback works on both single and multi-currency forms.

Setting frequency-specific amount options

If you’ve enabled recurring ask amounts on your Contribution form, those ask amounts get applied to each recurring frequency that you have enabled. Use this callback if you would prefer to set frequency-specific ask amounts. The example below sets 6 amounts for the Monthly frequency, and 6 larger amounts for the Yearly frequency.

(function() {

    window.nvtag_callbacks = window.nvtag_callbacks || {};
    window.nvtag_callbacks.alterFormDefinition = window.nvtag_callbacks.alterFormDefinition || [];

    function findElementByName(def, name){
        var elements = def.form_elements;
        for(var i = 0; i < elements.length; i++){
            var element = elements[i];
            if(element.name === name){
                return element;
            }
            if(element.children && element.children.length){
                var children = element.children;
                for(var j = 0; j < children.length; j++){
                    var child = children[j];
                    if(child.name === name){
                        return child;
                    }
                }
            }
        }
    }

    var frequencyLookup = {
        Weekly: 1,
        EveryTwoWeeks: 2,
        EveryFourWeeks: 3,
        Monthly: 4,
        Quarterly: 5,
        Yearly: 6,
        TwiceAYear: 7
    };

    var defaultFrequencyOptions = {};
    defaultFrequencyOptions[frequencyLookup.Monthly] = {
        options: [
            { val: '10.00', display: 'First Monthly' },
            { val: '15.00', display: null },
            { val: '25.00', display: null },
            { val: '35.00', display: null },
            { val: '50.00', display: null },
            { val: '100.00', display: 'Last Monthly' },
            { val:'other', display: 'Other:', other: true }
        ],
        default_value: '15.00'
    };
    defaultFrequencyOptions[frequencyLookup.Yearly] = {
        options: [
            { val: '20.00', display: 'First Yearly' },
            { val: '50.00', display: null },
            { val: '75.00', display: null },
            { val: '100.00', display: null },
            { val: '250.00', display: null },
            { val: '500.00', display: 'Last Yearly' }
            // no "Other" amount
        ],
        default_value: '50.00'
    };

    window.nvtag_callbacks.alterFormDefinition.push(function (args){
        var def = args.form_definition;
        if(def.type !== 'ContributionForm') return;

        var selectAmount = findElementByName(def, 'SelectAmount');
        if(!selectAmount || !selectAmount.frequencyOptions) return;

        for(var i = 0; i < selectAmount.frequencyOptions.length; i++){
            var opt = selectAmount.frequencyOptions[i];
            if(defaultFrequencyOptions[opt.value]){
                opt.options = defaultFrequencyOptions[opt.value];
            }
        }
    });

})();

Note, this callback only works on single-currency forms.

Populate Hidden Metadata Fields with alterPost

Use the alterPost callback to populate Hidden Metadata Fields using your own custom logic.

window.nvtag_callbacks = window.nvtag_callbacks || {};
window.nvtag_callbacks.alterPost = window.nvtag_callbacks.alterPost || [];

window.nvtag_callbacks.alterPost.push(function (args){
  args.data.oa_visitor_id = 'abc123';
});
