detecting DOM change event

Josh CodeJosh Code Posts: 675
I want to somehow detect when the DOM of a page is changed in any way whether it be text replacement, moving a node, removing or adding a new node... and have a JavaScript function to react to a change in some way. The specific way I react shouldn't be important to explain.

I have a brute force solution which involves storing a disconnected copy of the DOM and comparing them on a small time interval. Differences lead to the copy being updated to match once again and the event handler function called.

So I have an inefficient, overly complex solution but do you know of an easier, more efficient way to detect a DOM change?
