select a child element in jquery object

Question

Hi, I'm new to jquery and I have a basic question now.

I have a jquery object got from a jquery selector. e.g

var obj = $('#certainTR');

Now, I want to get the element in this object and I cannot use '#certainTR > date' in a selector because '#certain' is not passed in my subroutine. Is there anyway to make a selection base on a object? Thanks a lot in advance!

Answer 1

use .children()

var obj = $('#certainTR'); // #certainTR
obj.children('.date'); // #certainTR > .date
