Executing Javascript in a frameset

Question

<frameset name="main">
 <frame src="leftnav.php" name="leftframe"/>
 <frame  src="dashboard.php" name="rightframe" bgcolor="#000000"/>
</frameset>

Hey. I want to execute some JavaScript in the rightframe and that should then affect in the left frame.

I guess the question is... what do I need to prefix my javascript with so it is accessible in the left frame?

But sometime we need to fix or modify old stuffs without rewrite the page. — pinichi, Dec 29 '10 at 09:05
Precisely. Sometimes it is cheaper to not replace the templating system on a 2000 file PHP app... — ComputerUser, Jan 03 '11 at 11:29

If you are in a page wich is in the right frame and you want to access an element in a page in the left frame you can use for example:

var table=parent.leftframe.document.getElementById("information");

You can: parent.leftframe.var_name and parent.leftframe.function_name()

In a comment to the original question (above), @Valentin mentions that frames are "bad," but does not explain further. Here are some references that do:
