Wait for basic form to complete loading?

Hi all,

I'm having an issue when setting a multi-choice fields with selected options via JavaScript on page load. The issue occurs due to the choice control (multi-select) sometimes being a little on the slow side on page load and therefore my JavaScript is being called before the control has completed loading 🙄 I currently have it in a document.ready, but that doesn't seem to help too much. I could create a js interval to poll/hit the page for it appearing in the DOM but sounds a little rough. There must be a nice way?

Cheers,

$(document).ready(function () {
 if(PortalHelper.setMultiChoiceValues("gw_categories", [122880000,122880001])) {
 $(".log").append("setChoiceValues: OK<br/>");
 }
});

Not sure on this one.

Could try window.onload (I believe doc ready fires before window.onload)

Another way would be to work out something that is missing from the DOM until the control loads, then use a javascript mutationobserver to fire when it gets added to the DOM.

Thanks @Fubar. I'll just poll the dom until its finished loading. Thanks.

FYI: Using a mutationobserver is usually a better solution than using an interval/timer.
