iFrame Notifies Parent Window

[GR1EVER]

Is there any way for a frame to send some sort of message to the parent window. Right now, I have this site I am making, and I want certain things to change in the parent window based on the current location of the iframe.

I know that from the parent window, you can check the URL of the iframe by doing window.frames[0].location.href but I want the pages that load in the frame to notify the parent want URL it is so that the appropriate changes in the parent window can be made. But I don't even need it to do that much for me. As long as I can get a page that loads in the frame to send some sort of message to the parent, the parent could detect that the frame contents have changed and re-collect the required information.

Any ideas? thanks.

You can call a function in the parent like this:

parent.functionName();
