call a function in success of datatable ajax call

Solution 1:

You can use dataSrc :

Here is a typical example of datatables.net

var table = $('#example').DataTable({
    "ajax": {
            "type" : "GET",
            "url" : "ajax.php",
            "dataSrc": function ( json ) {
                //Make your callback here.
                alert("Done!");
                return json.data;
            }       
    },
    "columns": [
            { "data": "name" },
            { "data": "position" },
            { "data": "office" },
            { "data": "extn" },
            { "data": "start_date" },
            { "data": "salary" }
        
        ]
    } );

Solution 2:

You can use this:

"drawCallback": function(settings) {
   console.log(settings.json);
   //do whatever  
},

The best way I have found is to use the initComplete method as it fires after the data has been retrieved and renders the table. NOTE this only fires once though.

$("#tableOfData").DataTable({
        "pageLength": 50,
        "ajax":{
            url: someurl,
            dataType : "json",
            type: "post",
            "data": {data to be sent}
        },
        "initComplete":function( settings, json){
            console.log(json);
            // call your function here
        }
    });

This works fine for me. Another way don't work good

                'ajax': {
                    complete: function (data) {
                        console.log(data['responseJSON']);
                    },
                    'url': 'xxx.php',
                },

Solution 5:

For datatables 1.10.12.

$('#table_id').dataTable({
  ajax: function (data, callback, settings) {
    $.ajax({
      url: '/your/url',
      type: 'POST',
      data: data,
      success:function(data){
        callback(data);
        // Do whatever you want.
      }
    });
  }
});
