Answer 1

As a addition to the reference to the Ben Alman plug in I thought I would post this working example. It ]rRelies on an iframe which has a source page containing jquery authentication & data query script which then passes the result to {other domain} parent window using the message plugin.

NB message plugin will break if using JQ v9 as JQV9 does not use "browser" referenced in the plugin

1st step: Add the plugin code to both sending and receiving docs:

http://benalman.com/projects/jquery-postmessage-plugin/

2nd step: Add this to sending doc:

   $.postMessage(
$(X).html(),    
'http://DOMAIN [PORT]/FOLDER/SUBFOLDER/RECIEVINGDOCNAME.XXX'   
 )  ;      

Where X can be a local var containing preformatted json array or other stuff, and the http url here is the address of the receiving document.

3rd step: Add this to receiving doc:

    $.receiveMessage(
    function(event){
        alert("event.data: "+event.data);
                $("#testresults").append('
'+event.data+'
');

    },          
    'http://DOMAIN.COM OR SOMETHING'

);

Where the http url is the DOMAIN of the sending document. Good in IE 8, 9, FF16, safari Windows (windows wait x V9 not tested yet), safari x mac thing.

The result is any item you want out of another domain page (that you have access to..).
