    I want to render the values from two different columns into my jquery datatable

    .10.16/js/jquery.dataTables.min.js
.10.16/css/jquery.dataTables.min.css

$(document).ready(function(){

    var table = $('#table').DataTable({

         "ajax": {
                "url": "data.json",
                "dataSrc": "",
            },

         "columnDefs": [
            {
               "render": function (data, type, row) {
                   var result = 'The id is ' + data[0] + ' and the name is ' + data[1];
                        return result;
                    },
                    "targets": 0,
                },      

         ],

        "columns": [
                {
                    "data": "id"
                },
                {
                    "data": "name"
                }
            ]
    });

});

    data.json:

    [{
    "id": "12",
    "name": "Laura"
}]

    But my result is:

    The id is 12 and the name is undefined

    • 1 It should be row[0] not data[0]. – markpsmith Commented Oct 16, 2017 at 10:29
    • @markpsmith But then my result is: The id is undefined and the name is undefined – peace_love Commented Oct 16, 2017 at 10:30
    • it should be var result = 'The id is ' + row["id"] + ' and the name is ' + row["name"]; – juntapao Commented Oct 16, 2017 at 10:36

    Reset to default 8

    Please change the following:

    "columnDefs": [
            {
               "render": function (data, type, row) {
                   var result = 'The id is ' + row["id"] + ' and the name is ' + row["name"];
                   console.log(result);
                        return result;
                    },
                    "targets": 0,
                },      

         ]

    Use row["id"] instead of data[0];
