set html select option with jquery

Question

I have a list in a select. After selecting an option i do a check and occasionally i want to change the selected to index 0 (first option, value=""). How do i set the select to that option with jquery?

Answer 1

$('select > option')[0].attr('selected','selected') should work i think

Answer 2

Here's what you are looking for:

$('select > option')[0].selected = true;

Answer 3

select > option = get descendant of select :eq(0) means get the first (index=0) and then set attribute

$("select > option:eq(0)").attr("selected","selected")
