I am aiming to display the information received from my socket event in an ajax datatable

Utilizing socket to receive JSON data from the backend, I have the DATA variable containing the information I want to iterate into the AJAX data table. Below is the code snippet I am using:

`

 socket.on('getinvoices', (data) => {

                var table = $('#table1').DataTable( {
                   
                    dom: 'Bfrtip',
        buttons: [
            'copy', 'csv', 'excel', 'pdf', 'print'
        ],
        order: false,
                  ajax: {
                    url : "https://testdma.tech-east.com.pk/dma/invoices/getAllInvoices",
                    dataSrc: "doc",
                    order: [[0]], 
                  },
                  columns: [
                    { data: 'recipientName' },
                    { data: 'recipientAddress' },
                    { data: 'recipientPhoneNumber' },
                    { data: 'recipientEmail' },
                    { data: 'services[/ ].serviceName' },
                    { data: 'services[/ ].servicePrice' },
                    {
                    data: null,
                    className: "dt-center editor-delete",
                    orderable: true,
                    "mRender" : function ( data, type, row ) {
                        return '<button class="btn viewbtn" value=' +data._id +'>Edit</button>';
                    }
                },   
                {
                    data: null,
                    className: "dt-center editor-delete",
                    orderable: true,
                    "mRender" : function ( data, type, row ) {
                        return '<button class="btn viewbtn2" value=' +data._id +'>Print Invoice</button>';
                    }
                }          

                  ],
                });

The data received through the socket is stored in the DATA variable.

Previous attempts to replace the URL with DATA in the AJAX datatable were unsuccessful. Can you provide guidance on how to successfully display the table with the received data?

Answer №1

To update a jQuery DataTable with data received from a socket event, one can utilize the ajax.reload() method. Here is a demonstration of how this can be achieved:

// Setting up the table
var table = $('#table1').DataTable({
  dom: 'Bfrtip',
  buttons: [
    'copy', 'csv', 'excel', 'pdf', 'print'
  ],
  order: false,
  columns: [
    { data: 'recipientName' },
    { data: 'recipientAddress' },
    { data: 'recipientPhoneNumber' },
    { data: 'recipientEmail' },
    { data: 'services[/ ].serviceName' },
    { data: 'services[/ ].servicePrice' },
    {
      data: null,
      className: "dt-center editor-delete",
      orderable: true,
      "mRender" : function ( data, type, row ) {
          return '<button class="btn viewbtn" value=' +data._id +'>Edit</button>';
      }
    },   
    {
      data: null,
      className: "dt-center editor-delete",
      orderable: true,
      "mRender" : function ( data, type, row ) {
          return '<button class="btn viewbtn2" value=' +data._id +'>Print Invoice</button>';
      }
    }
  ]
});

// Listening for the 'getinvoices' socket event
socket.on('getinvoices', (data) => {
  // Updating the table data with the received data
  table.ajax.reload(null, false);
});

Furthermore, one can customize the data source and various other settings by providing an object to the ajax.reload() method.

table.ajax.reload({
  url: "https://testdma.tech-east.com.pk/dma/invoices/getAllInvoices",
  dataSrc: "doc",
  order: [[0]],
});
