How to Insert JSON data into DataTable

Question

I am new to Javascript and I am trying to dynamically load Json data into datatable on a button click.

My Json data is in below format

     [{"DeviceName":"AND1","IPAddress":"10.10.12.1221"},   {"DeviceName":"AND2","IPAddress":"10.10.12.1222"},{"DeviceName":"AND3","IPAddress":"10.10.12.1223"}]

Here is my complete Html code: When I am running this code, I am getting an UncaughtType error in processDeviceDataResults at ('#deviceTable'). But, I am pretty sure this is not the way you to load data in to the datatable.

   

                      
            //Set the hubs URL for the connection
            var url = 'http://localhost:8080/signalr';

            var connection = $.hubConnection(url);

            // Declare a proxy to reference the hub.
            var hubProxy = connection.createHubProxy('HubClass');

            hubProxy.on('DeviceDataResults', processDeviceDataResults);

            connection.start().done(function() {
                $("#GetDeviceData").click(function() {
                    hubProxy.invoke('GetDeviceData');
                });
            });

            function processDeviceDataResults(results) {                 
                $('#deviceTable').dataTable({
                    "aodata": results
                });
        }

Forgive me for the improper spacing, I dont see any spaces while editing it, but not sure how are they getting added after submission.... — marak

Try this

data.json

    {
    "data": [
        {
            "DeviceName": "AND1",
            "IPAddress": "10.10.12.1221"
        },
        {
            "DeviceName": "AND2",
            "IPAddress": "10.10.12.1222"
        },
        {
            "DeviceName": "AND3",
            "IPAddress": "10.10.12.1223"
        }
    ]
}

js

  $('#deviceTable').dataTable({
      "ajax": "data.json",
      "columns": [
        { "data": "DeviceName" },
        { "data": "IPAddress" }
    ]
  });

Jifho, Thanks for your response. I formatted my JSON data as you suggested and I am getting an "Uncaught TypeError: Undefined is not a function on $('#deviceTable').dataTable line. I have a table defined in my html body as <table id="deviceTable"> </table>

       $(document).ready(function () {

             var connection = $.hubConnection(url);

             var hubProxy = connection.createHubProxy('HubClass');

             hubProxy.on('DeviceDataResults',   processDeviceDataResults);

             connection.start().done(function () {
                 $("#GetDeviceData").click(function () {


                     hubProxy.invoke('GetDeviceData');
                 });


             });

             function processDeviceDataResults(results) {

                 $('#deviceTable').dataTable({

                 });
             }
         });

my JSON results:

     {"data":[{"DeviceName":"AND1","IPAddress":"10.10.12.1221"},{"DeviceName":"AND2","IPAddress":"10.10.12.1222"},{"DeviceName":"AND3","IPAddress":"10.10.12.1223"}]}

marak the data is loaded in other file via ajax

ajax.php

  <?php

//in ajax.php get json data
//Here you can create a function that returns the data
$response='
{
    "data": [
        {
            "DeviceName": "AND1",
            "IPAddress": "10.10.12.1221"
        },
        {
            "DeviceName": "AND2",
            "IPAddress": "10.10.12.1222"
        },
        {
            "DeviceName": "AND3",
            "IPAddress": "10.10.12.1223"
        }
    ]
}';

Jifho, I am getting the data in my results object. But I am not able to insert it into the table. While accessing the datatable ($('#deviceTable').dataTable), I am getting an Uncaught TypeError: Undefined is not a function error

Jifho Over a year ago

try first create the table with predefined data, without using the function processDeviceDataResults()

marak Over a year ago

Jifho, I solved it by adding the Jquery 1.11.1 reference above dataTable reference.

Yes Venkata they are referenced in the Head tags. This is the order in which they are referenced

src="text/javascript" src="Scripts/jquery-1.6.4.js"

src="//cdn.datatables.net/1.10.2/js/jquery.dataTables.min.js"

href="https://cdn.datatables.net/1.10.2/css/jquery.dataTables.min.css"
