Chromium extensions: Tips for executing a content_script once all document listeners have been activated

Is there a method to execute a chromium extension content_script after window.load and following all other window.load listeners have been activated?

I am currently analyzing a website's javascript in an attempt to enhance its functionality. However, I want these enhancements to take place only after all existing js code has completed.

What I am seeking is a mechanism to set a trigger once the site is prepared for modifications.

If there isn't a straightforward approach to achieve this, do you know of a universal function that could work with major JS frameworks like jQuery, prototype, etc?

By the way, this solution won't suffice as it will be executed before the page script's listeners which are added later:

window.addEventListener("load", callback, false);

Answer №1

Content script

(discussing the Manifest's content_scripts.run_at attribute)

There is no need to listen for the onload event when using content scripts set to run at document_idle, as they will always execute after the DOM has finished loading.

Since document_idle is the default mode, it should function as anticipated without needing an additional listener for page-load events – simply include the JavaScript code you wish to inject.
