ajax - Datatables display columns by Index rather than name -


the following code works fine me:

$(document).ready(function () {             var t = $("#users").datatable({                 columndefs: [{                     "searchable": false,                     "orderable": false,                     "targets": 0                 }],                 order: [[1, 'asc']],                 ajax: {                     url: "/api/users",                     datasrc: ""                 },                 columns: [                     {                         data: "id"                     },                     {                         data: "firstname"                     },                     {                         data: "lastname"                     },                     {                         data: "username"                     },                     {                         data: "id",                         render: function (data) {                             return "<a href='#'><i class='fa fa-eye js-view' data-id='" + data + "'></i></a> | <a href='#'><i class='fa fa-pencil js-edit' data-id='" + data + "'></i></a> | <a href='#'><i class='fa fa-trash js-delete' data-id='" + data + "'></i></a>";                         }                     }                 ],

is there way use column indexes instead of names this?:

$(document).ready(function () {             var t = $("#users").datatable({                 columndefs: [{                     "searchable": false,                     "orderable": false,                     "targets": 0                 }],                 order: [[1, 'asc']],                 ajax: {                     url: "/api/users",                     datasrc: ""                 },                 columns: [                     {                         data: 0                     },                     {                         data: 1                     },                     {                         data: 2                     },                     {                         data: 3                     },                     {                         data: 0,                         render: function (data) {                             return "<a href='#'><i class='fa fa-eye js-view' data-id='" + data + "'></i></a> | <a href='#'><i class='fa fa-pencil js-edit' data-id='" + data + "'></i></a> | <a href='#'><i class='fa fa-trash js-delete' data-id='" + data + "'></i></a>";                         }                     }                 ],

all want able display first 4 columns of web api source or choose 4 columns display index not name. possible?

instead of converting result of ajax call suggested, implemented "ugly hack" proved effective. surprised problem not solved conventionally "index" instead created pseudo-index grabs column names data attributes in table tag , fed numbered variables this:

 //display first 4 columns of data     var f1 = $(".grid").attr("data-f1");     var f2 = $(".grid").attr("data-f2");     var f3 = $(".grid").attr("data-f3");     var f4 = $(".grid").attr("data-f4");     var f5 = $(".grid").attr("data-f5");  //this value same f1     var t = $(".grid").datatable({         columndefs: [{             "searchable": false,             "orderable": false,             "targets": 0         }],         order: [[1, 'asc']],         ajax: {             url: "/api/users",             datasrc: ""         },         columns: [             {                 data: f1             },             {                 data: f2             },             {                 data: f3             },             {                 data: f4             },             {                 data: f5,                 render: function (data) {                     return "<a href='#'><i class='fa fa-eye js-view' data-id='" + data + "'></i></a> | <a href='#'><i class='fa fa-pencil js-edit' data-id='" + data + "'></i></a> | <a href='#'><i class='fa fa-trash js-delete' data-id='" + data + "'></i></a>";                 }             }         ],

this approach proved surprisingly flexible, swap display order of column on fly without changing code. still, have preferred indexed approach, though.
