Calling parent window function

[balaji_A]

Parent window script
<script language="javascript">
function show()
{
msgwindow = open('Page2.htm','window','width=200,height=200');
msgWindow.opener = self;
}
function func2()
{
alert('function called from child window');
}
</script>

In my page2.htm file i have one button. Onclick of the button should invoke the function by name 'funct2()' which is present in the parent window. How do i call a parent window function from child window?

Thanks.

msgwindow = window.open('Page2.htm','window','width=200,height=200');
}
function func2()
{

<input type="button" onclick="window.opener.func2()" value="Show funny alert">
