Backtrace JavaScript DOM Insert

I have a page that has several (20+) scripts that are being loaded. One of them is inserting an iframe into the DOM. Using the Chrome developer tools, is there anyway I can figure out when/where/how that iframe开发者_如何学编程 is being inserted into the DOM?

You could use Firebug's break on mutate. Otherwise you could disable one script after another an check when the iframe isn't insert anymore.
