When you are performing multiple ajax call like searching, paginating or sorting , server may takes much time to send response. The purpose of the Datatable custom loader is to show to the user that while the action has not yet completed, the computer is working on their request. As long as the interface clearly indicates to the user that their request was received and is pending, then the UI element has done its job.

By default datatable has a text loader “Processing…”, you can customize the message by
language option.

$(document).ready(function() {
   var dataTable =  $('#employee-grid').DataTable( {
   	processing: true,
	"language": {
		"processing": "Hang on. Waiting for response..." //add a loading image,simply putting <img src="loader.gif" /> tag.
	},
	serverSide: true,
	ajax: "employee-grid-data.php", // json datasource
    } );
} );

Today I will replace text message by an animated css3 loader. For this I have created two css files “dataTables.customLoader.walker.css” and “dataTables.customLoader.circle.css“.

datatable-custom-loader

You can use any one from here. You can also modify the css or add some different animation/style. “.dataTables_processing” class is holder of the datatable loader. Lets find it using firebug or any developers tools. Happy hacking.

    why does the demo take so long to process when I do a search?tks

    • Ndroo

      i think because they using shared resources that makes the demo takes so slow. but when you try to download and install on your environment it will be fast (i try at my server and it is fast)
