Node cannot be inserted at the specified point in the hierarchy

Hi,
can someone point out the error in my ways with the script at http://www.alphaworks.co.uk/test/add2.html ?

It gives a "Node cannot be inserted at the specified point in the hierarchy" error relating to line 26.

I can't see what I'm doing wrong, it would seem a valid thing to do. I've searched on the error but can't see anything which applies to my problem.

Thanks,
Geoff

Look carefully at your newTD function. What are you creating and returning from there? Oops!

Hope this helps,
Jeroen

It may be because the parentNode is not what think.

Code:

// This is what the browser assumes as the table hierachy
// even if you don't include the thead, tbody, or tfoot tags
<table>
  <thead>
    <tr><th></th></tr>
  </thead>
  <tbody>
    <tr><td></td></tr>
  </tbody>
  <tfoot>
    <tr><th></th></tr>
  </tfoot>
</table>

Add ... I'm pretty sure you're going to get TBODY.

Code:

window.alert(insert_press_before_here.parentNode.tagName);

Hi,
while you're right about the parentNode of the <tr> element being <tbody> and not <table> I don't think this actually caused the problem in this case. I have changed the names of the variables to match this though.

Thanks,
Geoff
