How to get number of selected options using jquery?

Question

You can use the :selected selector to select them, then get the .length, like this:

var count = $("#mySelect :selected").length;

You can get the number of selected items in the multiselect with the following:

$('#selectList :selected').length

Where #selectList is the id of your .

var n = $("input:checked").length; see this for more detail: http://api.jquery.com/checked-selector/

For checkboxes I'm using:

$('input[name="InputName"]:checked').size()
