Manipulate DataLabel with JavaScript

There's probably a much better way to do this, but here's my hacky solution:

I've noticed that the DOM may return a page loaded status before some SmartForms pages finish loading content.  I've gotten around this by setting a timer and checking if a content field is not null or has content and then manipulating page data.  For example:

function waitForLoad() {
    if (document.getElementById("someElementIDHere").innerHTML != "") {
        setTimeout(waitForLoad, 1000);
    }
    else {
        main();
    }
}

function main() {

    //your code here

}

waitForLoad();
