Steps

1. create a form (testme in this case) with hidden field. Get the Field Key value.

2. add script on Script n Styles:

header:

$ = jQuery;
$.urlParam = function (name) {
    var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.search);
    return (results !== null) ? results[1] || 0 : false;
}

footer:

$(document).ready(function(){
	$("#field_5zpwa").val($.urlParam('ref'));  // 5zpwa is the Field Key value for the hidden field
});
