Is it possible to append a script to an iframe ?

Question

Hi, i was wondering if i can add/append a javascript to an iframe which is loaded with an external web page that is not in my website. is it possible using jQuery or even simple javascript ?

  <script>
  // i need some code here
  </script>
  <iframe src="http://www.xxx.xxx/" id="myiframe" />

Note: i don't want to replace the content of the iframe, i just want to add the script

Thanks

Answer 1

If the iframe involves content from a different domain, the browser is not going to let your code poke around in it.

Answer 2

No, it's not possible (and quite rightly too) because it violates the same origin policy. It would be rather a large security hole to allow users to script content that's on another domain, anything would be possible from keyhooking to stealing personal data.

Answer 3

It's not possible due to security policy.

However, if you really want to do it, and have understand the security issues, you could give a try to a solution like Ajax Cross domain
