Add table row in jQuery

Question

What is the best method in jQuery to add an additional row to a table as the last row?

Is this acceptable?

$('#myTable').append('<tr><td>my data</td><td>more data</td></tr>');

Are there limitations to what you can add to a table like this (such as inputs, selects, number of rows)?

Answer 1

I recommend

$('#myTable > tbody:first').append('<tr>...</tr><tr>...</tr>'); 

as opposed to

$('#myTable > tbody:last').append('<tr>...</tr><tr>...</tr>'); 

The first and last keywords work on the first or last tag to be started, not closed. Therefore, this plays nicer with nested tables, if you don't want the nested table to be changed, but instead add to the overall table. At least, this is what I found.

<table id=myTable>
  <tbody id=first>
    <tr><td>
      <table id=myNestedTable>
        <tbody id=last>
        </tbody>
      </table>
    </td></tr>
  </tbody>
</table>

Answer 2

This can be done easily using the "last()" function of jQuery.

$("#tableId").last().append("<tr><td>New row</td></tr>");

Answer 3

You can use this great jQuery add table row function. It works great with tables that have <tbody> and that don't. Also it takes into the consideration the colspan of your last table row.

Here is an example usage:

// One table
addTableRow($('#myTable'));
// add table row to number of tables
addTableRow($('.myTables'));

I Guess i have done in my project , here it is:

html

<div class="container">
    <div class = "row">
    <div class = "span9">
        <div class = "well">
          <%= form_for (@replication) do |f| %>
    <table>
    <tr>
      <td>
          <%= f.label :SR_NO %>
      </td>
      <td>
          <%= f.text_field :sr_no , :id => "txt_RegionName" %>
      </td>
    </tr>
    <tr>
      <td>
        <%= f.label :Particular %>
      </td>
      <td>
        <%= f.text_area :particular , :id => "txt_Region" %>
      </td>
    </tr>
    <tr>
      <td>
        <%= f.label :Unit %>
      </td>
      <td>
        <%= f.text_field :unit ,:id => "txt_Regio" %>
      </td>
      </tr>
      <tr>

      <td> 
        <%= f.label :Required_Quantity %>
      </td>
      <td>
        <%= f.text_field :quantity ,:id => "txt_Regi" %>
      </td>
    </tr>
    <tr>
    <td></td>
    <td>
    <table>
    <tr><td>
    <input type="button"  name="add" id="btn_AddToList" value="add" class="btn btn-primary" />
    </td><td><input type="button"  name="Done" id="btn_AddToList1" value="Done" class="btn btn-success" />
    </td></tr>
    </table>
    </td>
    </tr>
    </table>
    <% end %>
    <table id="lst_Regions" style="width: 500px;" border= "2" class="table table-striped table-bordered table-condensed">
    <tr>
    <td>SR_NO</td>
    <td>Item Name</td>
    <td>Particular</td>
    <td>Cost</td>
    </tr>
    </table>
    <input type="button" id= "submit" value="Submit Repication"  class="btn btn-success" />
    </div>
    </div>
    </div>
</div>

js

$(document).ready(function() {     
    $('#submit').prop('disabled', true);
    $('#btn_AddToList').click(function () {
     $('#submit').prop('disabled', true);
    var val = $('#txt_RegionName').val();
    var val2 = $('#txt_Region').val();
    var val3 = $('#txt_Regio').val();
    var val4 = $('#txt_Regi').val();
    $('#lst_Regions').append('<tr><td>' + val + '</td>' + '<td>' + val2 + '</td>' + '<td>' + val3 + '</td>' + '<td>' + val4 + '</td></tr>');
    $('#txt_RegionName').val('').focus();
    $('#txt_Region').val('');
        $('#txt_Regio').val('');
        $('#txt_Regi').val('');
    $('#btn_AddToList1').click(function () {
         $('#submit').prop('disabled', false).addclass('btn btn-warning');
    });
      });
});

Answer 5

<table id=myTable>
    <tr><td></td></tr>
    <style="height=0px;" tfoot></tfoot>
</table>

You can cache the footer variable and reduce access to DOM (Note: may be it will be better to use a fake row instead of footer).

var footer = $("#mytable tfoot")
footer.before("<tr><td></td></tr>")

Answer 6

Neil's answer is by far the best one. However things get messy really fast. My suggestion would be to use variables to store elements and append them to the DOM hierarchy.

HTML

<table id="tableID">
    <tbody>
    </tbody>
</table>

JAVASCRIPT

// Reference to the table body
var body = $("#tableID").find('tbody');

// Create a new row element
var row = $('<tr>');

// Create a new column element
var column = $('<td>');

// Create a new image element
var image = $('<img>');
image.attr('src', 'img.png');
image.text('Image cell');

// Append the image to the column element
column.append(image);
// Append the column to the row element
row.append(column);
// Append the row to the table body
body.append(row);
