Question

Is there an event in JQuery, Javascript, or the DOM in general that I can subscribe to that will notify me when an element become visible or invisible (display:none)?

Answer 1

There are events for DOMAttrModified and onpropertychange (IE) that can track DOM element changes and fire an event.

Wrote about this with a jQuery plug-in that allows monitoring changes to CSS styles here:

This might be just what you need as you could do something like:

$("#myControl").watch("display,visibility", function() { showStatus("changed...") });
