Answer 1

Try this code:

$('#1 input').val();​

New code after your edit in your answer

$('#2tr td:eq(1) input').val();

is what you want?

Answer 2

There is no textbox in tr with id '1', so I guess you wnat this one out of tr with id '2'...

You can write:

$('#2 td input').val()

But it is not recommended to use number as ID in an HTML-DOM!
