detect error in iframe

[babadi]

Hi folks,

Suppose I have an iframe defined as:

<iframe name='test' id='test' src='http://www.google.com/'></iframe>

Is there any way for the document to detect whether the contents of the iframe has successfully loaded or if an error has occurred?

Thanks,
Martin

If the content is external, you can't directly check due to javascript security limitations. But you can check before you try to load it, either server-side or client-side.
Since you posted in the JS forum, here's the JS solution for checking for 404. Modify as desired to check for other errors.
