How do I get the iframe that opened a window in JavaScript from Internet Explorer?

Question

I have an iframe that opens a new webpage.

In that webpage, I want to access a function on the window of the iframe.

I try to call window.opener.myFunction() , but the opener is the <iframe> 's parent window, and not the <iframe> 's window.

Because of the dynamic nature of the page, I don't want to explicitly get the contentWindow of the <iframe> from the parent window. Does anyone know of a workaround?

Answer 1

If you know the <iframe> 's id, you could use getElementById().

For example:

The first webpage would have:

<iframe id="launcher"></iframe>

And the launched page could use:

window.opener.getElementById("launcher").myFunction();
