JSONP is one of several methods to allow the use of JSON data from any server
(browsers have XSS protection rules which will block standard Ajax requests to remote source for security reasons). Using JSONP allows DataTables to load
server-side sourced data from any domain and is quite simply done with the dataType option of the ajax initialisation option.
When given as an object, the ajax
option maps directly onto the jQuery ajax options (i.e. any option that can be used in jQuery's Ajax function can
also be used in DataTable's ajax
option).
The example below shows ajax being
used with the dataType option set to retrieve JSONP data for server-side processing in DataTables.
The Javascript shown below is used to initialise the table shown in this example:
1 2 3 4 5 6 7 8 9 10 | $(document).ready(function() {
$('#example').DataTable( {
"processing": true,
"serverSide": true,
"ajax": {
"url": "scripts/jsonp.php",
"dataType": "jsonp"
}
} );
} );
|
In addition to the above code, the following Javascript library files are loaded for use in this example:
The HTML shown below is the raw HTML table element, before it has been enhanced by DataTables:

This example uses a little bit of additional CSS beyond what is loaded from the library files (below), in order to correctly display the table. The
additional CSS used is shown below:

This table loads data by Ajax. The latest data that has been loaded is shown below. This data will update automatically as any additional data is
loaded.
