在数据表 ajax 调用成功时调用 function

Question

Is that possible to invoke a javascript function in success of datatable ajax call. Here is the code am trying to use,

var oTable = $('#app-config').dataTable(
            {
                "bAutoWidth": false,                                                
                "bDestroy":true,
                "bProcessing" : true,
                "bServerSide" : true,
                "sPaginationType" : "full_numbers",
                "sAjaxSource" : url,                    
                "fnServerData" : function(sSource, aoData, fnCallback) {
                    alert("sSource"+ sSource);
                    alert("aoData"+ aoData);
                    $.ajax({
                        "dataType" : 'json',
                        "type" : "GET",
                        "url" : sSource,
                        "data" : aoData,
                        "success" : fnCallback
                    });
                }

is it possible to have something like,

success : function(){
    //.....code goes here
}

instead of "success": fnCallback ------> which is last line of AJAX call. In this function I would like to check a value send from server side.

Answer 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" }

        ]
    } );

Answer 2

You can use this:

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

Answer 3

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
        }
    });

Answer 4

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.
      }
    });
  }
});

Answer 5

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

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

Answer 6

The success option of ajax should not be altered because DataTables uses it internally to execute the table draw when the data load is complete. The recommendation is used "dataSrc" to alter the received data.

Answer 7

Based on the docs , xhr Ajax event would fire when an Ajax request is completed. So you can do something like this:

let data_table = $('#example-table').dataTable({
        ajax: "data.json"
    });

data_table.on('xhr.dt', function ( e, settings, json, xhr ) {
        // Do some staff here...
        $('#status').html( json.status );
    } )

Answer 8

Maybe it's not exactly what you want to do, but using the ajax complete solved my problem of hiding a spinner when the ajax call returned.

So it would look something like this

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

Answer 10

As per the question, I think the following should suffice:

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

            "bDestroy":true,
            "bProcessing" : true,
            "bServerSide" : true,
            "sPaginationType" : "full_numbers",
            "sAjaxSource" : url,                    
            "fnServerData" : function(sSource, aoData, fnCallback) {

                    "success" : fnCallback
                }).success( function(){  alert("This Function will execute after data table loaded");   });
            }
