Checking a frames src

using a frame src in an If Else statement

[Tamarick]

I want to return values based on the one of the parent's child frame src.

Here's a real basic example of what I'm trying to do:

<script type="text/javascript">
if (parent.frames.mainframe.src = 'FOO.html')
{
document.write('It is foo!');
}
else
{
document.write('Not foo Yo!');

}
</script>

It always returns the top statement. No matter what the actual src is.

The frame source is originally set to 'FOO.html'. Even if the content document of that frame is changed later on, the top-level frameset document doesn't know about it and so the src property still returns the same value.

You can reference the current URL of the child frame by going right down to the child's document object, like this:

parent.frames.mainframe.document.location.href

(fingers crossed that I got the referencing right!)

Tamarick, in your current if-statement you're using a single =. That makes it an assignment operator. What you need here is the comparison operator: ==
