See HTML of page after modified by Javascript

Is there any way to see the page in Firebug or other soft开发者_高级运维ware after the content of a div has been replaced with ajax?

Yes, that's exactly what Firebug will show you: the current state of the DOM. Same with Chrome's developer tools.

Sure, you can inspect the DOM with FireBug which always shows the DOM at its most recent state (and of course accounts for AJAX updates):

yes firebug marks the changed div in yellow and you can see the html dynamic updates in the html view
