Ninja Forms JavaScript Hook

ninja-forms.js

var form_id = 3;

// listen to all ajax completed events
jQuery(document).ajaxComplete(function (event, jqXHR, ajaxOptions) {

	// try to parse response
	var data = JSON.parse(jqXHR.responseText || '{}');

	// check if the ajax request is for our form
	if (data.data.form_id == form_id) {
		var fields = data.data.fields || {};

		// search for email in fields
		var email = Object.keys(fields).reduce(function (email, field) {
				var element = fields[field];
				if (element.element_class == 'email-element' && !email) {
					return element.value;
				}

				return email;
			}, null);

		// check if the email was found
		if (email) {
			console.log(email);
			// send email to leadbi
		}
	}
});

This doesn't seem to work anymore with version 3 as there is no AJAX event that I can see in the network console.
