Setting attributes for the first column's contents with jquery

Question

I have the following table which is loaded dynamically into a <div>.

Now I am trying to traverse into the table as to disable all the input fields in the first column titled "index". How would I go about that?

What I have come up with is the following, but it fails:

$('#output').find('tr').each().find('td').first().find('input').attr('disabled','disabled');

Answer 1

This should work as well.

$('#output tr td:first-child input').attr('disabled', 'disabled');

Everything in one selector. Tested in chrome only

Answer 2

$('table tr td:nth-child(1) input').prop('disabled',true)

Since you didn't post the HTML for your table, I offer a generic example. You may be able to replace the selector with $('#output td:nth-child(1) input') depending on your exact code.
