APM - Track clicks on webtop resources

Well close.. Still didn't seem to be hitting 100%. But the following modification seems to be working much better..

window.onclick = function (e) {
    if (e.target.parentNode.className == "favorite" || e.target.parentNode.className == "image" || e.target.parentNode.className == "caption") {
        var xhttp = new XMLHttpRequest();
        console.log(e.target.parentNode.id);
        var parentNodeId = "";

        //populate parent's parent
        if (e.target.parentNode.parentNode.id) {
            parentNodeId = e.target.parentNode.parentNode.id;
        }
        //overwrite parent's parent if parent not null
        if (e.target.parentNode.id) {
            parentNodeId = e.target.parentNode.id;
        }

        //open link
        if (parentNodeId) {
            var uri = "/analytics?t=" + Math.random() + "&r=" + encodeURIComponent(window.btoa(parentNodeId)) + "&d=" + Date.now();
            xhttp.open("GET", uri, true);
            xhttp.send();
        }
        //log failed result
        else {
            console.log("Parent ID is NULL");
        }
    }
};
