How to track DOM change in chrome extension?

Question

I am writing a chrome extension where I want to fetch all the images exist on a page but some of the images load after some time (may be through ajax) which I could not fetch once the DOM is idle. Is there any way to track the DOM change after the page is loaded?

You can use document.addEventListener with the DOMNodeInserted event. Your callback will have to check each node insertion to see if it is the type of node you are looking for. Something like the following should work.

function nodeInsertedCallback(event) {     console.log(event); }; document.addEventListener('DOMNodeInserted', nodeInsertedCallback);
