Using javascript to create table rows containing form elements

**laptopalias** · 04-28-2011 11:00 AM

Like this? Firebug's giving me an error:

document.getElementById(tabid) is null
var root = document.getElementById(tab...ntsByTagName('tbody')[0]; //the root

Code:

OK, this is much more along the lines of what I was after; hope it helps someone else...

Code:

<form>
<table id = 1>
          <thead>

          <tr>

          <th>Mon 25/04/11</th>

          <th>Project</th>

          <th>Description</th>

          </tr>

          </thead>

          <tbody>
          <tr><td></td>

          <td><select>

<option>project 1</option>

<option>project 2</option>

<option>project 3</option>

<option>project 4</option>

<option>project 5</option>

</select></td>

          <td><input type = 'text'/></td>

          </tr>

          </tbody>
          </table>
<p>
<input type='button' value='Add' onclick='addRowClone(1);' />
</p> <table id = 2>
          <thead>

          <tr>

          <th>Tue 26/04/11</th>

          <th>Project</th>

          <th>Description</th>

          </tr>

          </thead>

          <tbody>

Sorry for reviving this old thread. I am trying to add some data of the selected items in a a text field , but am not able to do that, as data from the first select keeps repeating. I dont have much knowledge of JavaScript. Will greatly appreciate any help.

Here is a sample of what I am trying to do with another script included:

      $("[name^=price]").val($(this).find("option:selected").attr("data-price"));
    })
