Can a Google Chrome extension detect when all scripts finish loading?

I want to develop a Chrome extension that scrapes data off the page, but this can happen only after all of the pages ajax finish loading their remote content.

Is this possible?

I think you can't do that, but if you want to check if a particular external script is loaded you can check this: Verify External Script Is Loaded

In general, you can't detect when all scripts are finished loading. It is fairly common for a page to wait a couple seconds after the 'onload' event to request an additional round of scripts -- for example, if you want to delay-load ads but don't want to slow down the initial page rendering.

However, extensions do have a flag to run at "document_idle". This flag supposedly makes Chrome wait until the page is "idle" before injected the extension's script. It would not, however wait for a delay-loaded script and it may not even wait for a slow XHR.
