Ajax Loading and Saving

This example shows how the StateRestore extension can be operated over ajax.

To do this the ajax option of the stateRestoreConfig configuration object has to be set to a url that will be used when attempting to save the states. States are then loaded again via the tables own ajax url. If there is a stateRestore property in the json that is initially passed then the states present there will be loaded into the table.

It is worth noting that we only provide the client side implementation. You will have to write your own server side implementation to save states for longer than the current session.

The Scroller extension is also being used here. This is because it is a common use of loading over ajax.

The Javascript shown below is used to initialise the table shown in this example:

$('#example').DataTable({
	ajax: {
		url: '../data/stateRestoreLoad.php',
		dataSrc: 'data'
	},
	layout: {
		topStart: {
			buttons: [
				'createState',
				{
					extend: 'savedStates',
					config: {
						ajax: '../data/stateRestoreSave.php'
					}
				}
			]
		}
	},
	scrollY: 200,
	scrollCollapse: true
});

new DataTable('#example', {
	ajax: {
		url: '../data/stateRestoreLoad.php',
		dataSrc: 'data'
	},
	layout: {
		topStart: {
			buttons: [
				'createState',
				{
					extend: 'savedStates',
					config: {
						ajax: '../data/stateRestoreSave.php'
					}
				}
			]
		}
	},
	scrollY: 200,
	scrollCollapse: true
});

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.
