How to get iframe src page title and then set main page title

To get iframe src page title and then set main page title::

Unless the webpage is in the iframe is from the same domain as the containing page, it is impossible.

If they do have the same domain, then try the following:

document.title = document.getElementById("iframe").documentElement.title; 

In case you anyway want to do it using jquery, you can do it as following:

var title = $( "#frame_id").contents( ).find( "title").html( ); 
$( document).find( "title").html( title); 

And pay attention as stated above, you can do it only when script running and page in the same domain, otherwise it's useless.
