Check if frame exists

[therealwesfoster]

I have 2 frames.

 

TOP and HOME

 

Sometimes the top frame gets removed by accident. I'm needing a short JS script that checks "if TOP frame doesn't exist, redirece to index.html"

 

Which I would think would be like:

if (!window.parent.top)
{
  document.location.href = "index.html";
}

 

But it don't work. Help please.

 

Thanks

Well, i ended up doing this:

 

if (self != top)
{
  document.location.href = "./index.html";
}

 

Works just the same

 

SOLVED (although, if you have an answer to my question, feel free to post it. I like learning new things)
