Interaction between pages is only allowed if one page is a child of another, in other words the second page was launched by the first.

For the parent to access a child:

    function GetFrameByLocation(locationName) {
        for (var x = 0; x < window.frames.length; x++) {
            if (window.frames[x].location.href.indexOf(locationName) > 0)
                return window.frames[x];
        }
        return null;
    }
	
	var frame = GetFrameByLocation("p2");
	frame.window.document - this is the DOM for p2.
	
for the child to access the parent:

	parent.window.document
