Javascript/Jquery how to get Key from Key/Value

Question

I have a field called City that is a drop down. It has a key value pair.

To get the value, I can simply do the following in Jquery:

    var city = $("#city").val();

How do I get the key value though?

Answer 1

if it's a option within a select, try .text().

Answer 2

so you want the text of the selected option:

$('#city').find('option:selected').text();
