How do I check how many options there are in a dropdown menu?

Question

How do I check, using jQuery, how many options are there in a drop down menu?

Thanks.

Answer 1

var length = $('#mySelectList').children('option').length;

or

var length = $('#mySelectList > option').length;

This assumes your <select> list has an ID of mySelectList.
