Call javascript function from main page

Question

I've a framed page, called main.xhtml. Inside that page is the following code block:

<html>
<body>
<script>
javascriptCode
</script>

<frameset cols="234,*" border="0" frameborder="no">
   <frame src="LeftPage.html"  />
   <frame src="RightPage.html" name="main" />
</frameset>

</body>
</html>

How can I call the javascriptCode from inside LeftPage.html or RightPage.html? For example, I'll click on a button on LeftPage.xhtml and javascriptCode in the main page will be triggered. Thanks.

not the duplicate one, i just added extra example about what i want. tnx — mudcup, Jan 10 '12 at 14:07
While frames may not be the best choice (understatement), see if the info on this page helps you along: http://www.yourhtmlsource.com/javascript/scriptingframes.html — David Brainer, Jan 10 '12 at 14:20

window.parent.fn()

calls the function fn defined as a global variable in the parent frame.

It works because, in the browser, window is the global object whose properties alias global variables, so window.parent points to another frame's global object so its properties are the globals for code loaded in that other frame.
