I tested it using parent.php and child.php as the script names and href source

That only works if the parent page and child page are on the same (full) domain. If they are not, then the short answer is you cannot do it*, as this is considered cross-site scripting (google same origin policy).

 

 

*The longer answer is there are ways around it, along the same principle as FB API but it is kinda complex and involved, though it's somewhat easier depending on what you're coding for. For example there is an html5 method that's a bit less convoluted.
