Segment integration code to be used on Instapage

instapage-segment.js

// callback to trigger code upon a landing page form submit - the main call to action.
window.instapageFormSubmitSuccess = function( form ){
   // Instapage is a bit quirky with how it captures values of the form submit, but you should be able to use this code and replace the form fields with whatever your page is capturing.
   var firstName = ijQuery( form ).find( 'input[name="' + window.base64.base64_encode( 'First Name' ) +'"]').val();
   var lastName  = ijQuery( form ).find( 'input[name="' + window.base64.base64_encode( 'Last Name' ) +'"]').val();
   var email     = ijQuery( form ).find( 'input[name="' + window.base64.base64_encode( 'Email') +'"]').val();
   
   // Segment identify call.
   analytics.identify(email, {
       firstName: firstName, 
       lastName: lastName, 
       email: email
   });
   
   // Segment event track call. You'll want to capture the variant for a/b testing purposes.
   analytics.track("Form Submission", {
       firstName: firstName, 
       lastName: lastName, 
       email: email,
       pageId: window.__page_id,
       pageDomain: window.__page_domain,
       pageName: document.getElementsByName("Page Shown")[0].value,
       schoolName: "FooBar University",
       variant: window.__variant_custom_name
    });
