how to get fully computed HTML (instead of source HTML)?
Given a webpage that uses lots of javascript to generate its HTML, how can I get the final computed HTML being parsed by the browser instead of the source HTML? In other words, presume a page has lots of tags surrounding javascript functions that, when called, return some HTML. When I view the source of the page, I see the script function call, not the HTML it produces.
How could I get all of the HTML produced by a webpage?
I've noticed that Firebug appears able to see the HTML instead of the scripts, but it doesn't appear to have any way to save the whole page, only little segments of it.
Update:
Thanks for all the answers. However, I'm still not getting the HTML I see in Firebug's console with any of those techniques. For my example page, I'm using the 'Info' tab of my own Facebook profile. If you view source on that page, you'll see lots of scripts with the title 'big_pipe.onPageletArrive()'. However, if you look at it in Firebug, each of those function calls renders out to HTML. I tried the right-click on the tag in Firebug, the View Generated Source in the Webdev Toolbar, and the Chrome suggestion, but they all give me the script call, not the HTML.
Any other ideas?
Update 2:
When I said each of those functions renders out to HTML in Firebug, I wasn't quite correct. They only render out if I select them in the page and right click->Inspect Element. Then it appears to render it out. So maybe my question has become how do you get Firebug to automatically render out all of the HTML so you can select and save it? (Or I'm open to any other solution for grabbing this HTML).
Answer
With Firebug's HTML tab, you can right click on the <html> element, and click "Copy HTML".
You can do the same thing with Developer Tools in Chrome/Safari.
