Question

How to append a textbox to a table row with jQuery?

Answer 1

How can you append an input type to a table row? You have to append it to a table cell, if not you can position it absolute at the position of the table row. You can’t append it to a row via the DOM,

Seeing your other question, why don’t you add an input type hidden to the first cell of the row? You could easily do this like this:

$('tr#id td:first').append($('<input type="hidden" id="hidden_field" name="hidden_field" value="your value" />'));
