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 ajaxDT initialisation
option.
When given as an object, the ajaxDT 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 ajaxDT option).
The example below shows ajaxDT being used with the
dataType option set to retrieve JSONP data for server-side processing in DataTables.
| Name | Position | Office | Extn. | Start date | Salary |
|---|---|---|---|---|---|
| Name | Position | Office | Extn. | Start date | Salary |
The Javascript shown below is used to initialise the table shown in this example:
$(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:
The following CSS library files are loaded for use in this example to provide the styling of the table:
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.
The script used to perform the server-side processing for this table is shown below. Please note that this is just an example script using PHP. Server-side processing scripts can be written in any language, using the protocol described in the DataTables documentation.
