Capture UTMs in OptimizeLeads form

Add the fields you would like to capture in Optimize Press

Don't worry if you can't make them hidden right now.

Add the following code in Footer in Tracking

<script>
var vars = ["utm_campaign","utm_medium","utm_source","utm_term","utm_content","gclid","handl_original_ref","handl_ip","fbclid","_fbc","_fbp","gaclientid","user_agent"]
for (v of vars){
	document.querySelector("[placeholder='"+v+"']").style.display="none"
}

window.addEventListener('message', event => {
if (event.data.handl) {
	merged = event.data
	for (v of vars){
		if (merged[v] != undefined){
			console.log(v, merged[v])
			var input = document.querySelector("[placeholder='"+v+"']")
			input.value=merged[v]
			input.setAttribute('value', input.value);
		}
	}
}
});
</script>

$('.optimize-leads-link-trigger').click(function(){
    setTimeout(function(){
        var merged = jQuery.extend( {'handl':true}, handl_utm )
        var frames = document.getElementsByClassName("optimize-leads-frame")
        for (frame of frames){
            frame.contentWindow.postMessage(merged, '*');
        }
