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

$("#mydropdown option").length

Or if you already got a reference to it,

$(myDropdown).find("option").length

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

or

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

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