can I catch exception of Iframe in parent window of Iframe

Question

I have an IFrame in a page and IFrame has some JavaScript. At run time JavaScript in IFrame gives exception which i want to catch on parent window. How to do that?

Answer 1

The only way is if the frame is on the same domain, in which case you can do, from parent:

iframe.contentWindow.onerror = function(){
    // handle error
}
