Is there any onDocumentChange event?

Question

Is there any event in Internet Explorer, that is fired whenever DOM is changed? For example:

document.attachEvent(\"ondocumentchange\", function () {
    ale

You want to look at dom mutation events - see http://en.wikipedia.org/wiki/DOM_Events, and scroll down to the section on mutation events. Only problem is that support for these events is pretty sketchy, so be careful using them. Notably, a lack of support at all in IE or Opera. Firefox, Safari and Chrome seem to be the only ones.

Something like:

document.addEventListener("DOMSubtreeModified", function () {
    alert("you've just changed DOM!");
});

According to http://www.quirksmode.org/dom/events/index.html for these kind of events you need to use addEventListener, not attachEvent. The event apparently bubbles, so that should be fine.
