<i>DataTables</i> server-side processing example with JSONP
|

</div>
|

|

<h1>Preamble</h1>
|
||||
<p><a href="http://bob.pythonmac.org/archives/2005/12/05/remote-json-jsonp/">JSONP</a> is a method of using JSON data from any server, regardless of XSS protection that modern browsers use. It is very useful for being able to retrieve JSON data from any domain name you choose and is easy to integrate with DataTables, thanks to jQuery's Ajax handler, as shown in this example.</p>
