Adding new data from JSON to existing table

Question

I am trying to add new data (from JSON) to existing table (using jquery).

In my html I have this table for example:

<table data-role="table" data-mode="columntoggle" class="ui-responsive" data-column-btn-text="Filter Columns" id="MyTable">
  <thead>
    <tr>
      <th data-priority="1">A</th>
      <th data-priority="2">B</th>
      <th data-priority="3">C</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>a1</td>
      <td>b1</td>
      <td>c1</td>
    </tr>
  </tbody>
  </table>

I am trying to do this (for adding new data from JSON):

var response = [{
      "A":"a2",
      "B":"b2",
      "C":"c2"
     },
     {
      "A":"a3",
      "B":"b3",
      "C":"c3"
    },
    {
      "A":"a4",
      "B":"b4",
      "C":"c4"
    }];

    $.each(response, function(i, item) {
                $('<tr>').html(
                //"<tr>" +
                "<td>" + response[i].A + "</td><td>" + response[i].B + "</td><td>" + response[i].C + "</td>" + "</tr>").appendTo('#MyTable');
        });

Why doesn't it work?

Answer 1

You're appending the content to the table itself and not to the thead or tbody elements, which is what should be done. Try changing your selector in .appendTo to #MyTable tbody and it will work. Demo here.

Answer 2

You were accessing the object in wrong way.Try this code snippet.

$.each(response, function(i, item) {
                    $('<tr>').html(
                      "<td>" + item.A + "</td><td>" + item.B + "</td><td>" + item.C + "</td>" + "</tr>").appendTo('#MyTable tbody');
            });

Answer 3

Use $('<tbody>').append instead of $('<tr>').html().

$.each(response, function(i, item) {
    $('<tbody>').append(
    "<td>" + response[i].A + "</td><td>" + response[i].B + "</td><td>" + response[i].C + "</td>" + "</tr>").appendTo('#MyTable');
});

You can see it in action at this JSFiddle.

Answer 4

Try the following snippet. This creates the 'tr' elements in the html.

    $.each(response, function(i, item) {
$("#MyTable tbody").append("<tr> <td>" + response[i].A + "</td><td>" + response[i].B + "</td><td>" + response[i].C + "</td>  </tr>");                 
            });

Answer 5

Do this:

table_html = '';
$.each(response, function(index, value) {
table_html += "<tr><td>"+value["A"]+"</td><td>"+value["B"]+"</td><td>"+value["C"]+"</td></tr>"   
        });

Give some id to <tbody> tag.

$("tbodyid").html(table_html);
