Javascript Question

Is there a JavaScript/jQuery DOM change listener?

Essentially I want to have a script execute when the contents of a DIV change. Since the scripts are separate (content script in chrome extension & webpage script), I need a way simply observe changes in DOM state. I could set up polling but that seems sloppy.


This answer is now deprecated.

See the answer by apsillers.

Since this is for a Chrome extension, you might as well use the standard DOM event - DOMSubtreeModified. See the support for this event across browsers. It has been supported in Chrome since 1.0.

$("#someDiv").bind("DOMSubtreeModified", function() {
    alert("tree changed");

See a working example here.
