URL of Iframe that is generated by script

[jasonhouse]

Iframe is generated on my page by a script like this...

<script src="http://example.com/make_iframe"></script>

How can I get the URL/SRC of the generated iframe?

Or is this not something that can be done with javascript?

The script that makes the iframe would have to create a reference to the window.

Otherwise there is no way? or just not with JavaScript?

If the iframe has an identifier then it can be possible to get the specific iframe, and another more brute force method is to get all iframe elements.

// get the iframe by an identifier
iframe = document.getElementById('myIframe');
// get the iframe from an element list
iframe = document.getElementByTagName('iframe')[0];
 
// get the src of the frame
var url = iframe.getAttribute('src');

Unfortunately the script does not print the iframe code to source code of page so that wont work. I only see the script itself in the page source.

That's fine because scripts don't look at the source code.
