Cross Domain Posting using PHP and JavaScript: ITS POSSIBLE!

Well.....finally i have worked out how to post cross-domain data which is restricted by browser's security policies.
WHAT IS IT??
This will be used for posting AJAX requests via java-script to any web-service or web-page in any DOMAIN and also get back the results from there.

HOW TO USE IT ?

Simply use this function in your java script

function jsonp(url, callback, name, query) 
{
    if (url.indexOf("?") > -1)
        url += "&jsonp="
    else
        url += "?jsonp="
    url += name + "&";
    if (query)      
        url += query+ "&";
    url += new Date().getTime().toString(); // prevent caching
    var script = document.createElement("script");
    script.setAttribute("src", url);
    script.setAttribute("type", "text/javascript");
    document.body.appendChild(script);
}

CALLING THIS FUNCTION from JavaScript :

jsonp("url of web page to be posted","", "function to be called back to receive result from the page","parameters  to be passed");

eg:

jsonp('http://example.com/test.php', '', 'loadData', "userid=" + userid + "&name=test" );

ON WEB SERVICE :(like on http://example.com/test.php):

<?php
if(isset($_REQUEST['jsonp']) && $_REQUEST['jsonp'] !== '')
{
 loadData("Welcome to cross domain posting.)";
}
>?

//callback here is your function (loadData) that should be present on your JavaScript

BACK ON JAVASCRIPT:

loadData(result)
{
 alert(result);
}

Which will alert you 'Welcome to cross domain posting.' that i have passed from test.php page in another domain.
This is it...
If u have any query plz let me know .......best O" lcuk...:)
