Capture GCLID On Website & Hidden Form
Hi,
I'm wanting to capture the GCLID cookie on my website then transfer that to a hidden form field within my Marketo forms, so I can get the offline conversion attribution. I have already created the hidden form, set to capture based on cookie, but I haven't figured out how to get the cookie to be stored on my website.
Below is the code I have been given to capture the GCLID on my website; however, it is written for form ID - not form name. Does anyone know how to rewrite the code or know other alternatives, so I can capture the information and send the cookie GCLID information to that hidden field and appropriate form name?
function getParam(p) {
var match = RegExp('[?&]' + p + '=([^&]*)').exec(window.location.search);
return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
}
function getExpiryRecord(value) {
var expiryPeriod = 90 * 24 * 60 * 60 * 1000; // 90 day expiry in milliseconds
var expiryDate = new Date().getTime() + expiryPeriod;
return {
value: value,
expiryDate: expiryDate
};
}
function addGclid() {
var gclidParam = getParam('gclid');
var gclidFormFields = ['gclid_field', 'foobar']; // all possible gclid form field ids here
var gclidRecord = null;
var currGclidFormField;
var gclsrcParam = getParam('gclsrc');
var isGclsrcValid = !gclsrcParam || gclsrcParam.indexOf('aw') !== -1;
gclidFormFields.forEach(function (field) {
if (document.getElementById(field)) {
currGclidFormField = document.getElementById(field);
}
});
if (gclidParam && isGclsrcValid) {
gclidRecord = getExpiryRecord(gclidParam);
localStorage.setItem('gclid', JSON.stringify(gclidRecord));
}
var gclid = gclidRecord || JSON.parse(localStorage.getItem('gclid'));
var isGclidValid = gclid && new Date().getTime() < gclid.expiryDate;
if (currGclidFormField && isGclidValid) {
currGclidFormField.value = gclid.value;
}
}
window.addEventListener('load', addGclid);
Thanks!
