Can we use $(this) with other selector?

Question

For ex.:

$("#"+$(this).attr("id")+" option[value='0']")

Can we reduce the code to something like

$(this+" option[value='0']") 

Answer 1

These will do the same as your first statement: find the option elements having 0 as their value and being the (not restrictively direct) child of this.

$(this).find('option[value="0"]')

or

$('option[value="0"]', this)
