Getting selected items count ListBox with jQuery

Question

As in topic - how to get selected items count in ListBox with jQuery, while user is selecting new item?

I have these code:

@Html.ListBoxFor(x => Mode         


        

Answer 1

Adding my comment as answer....

If it is a multi-select, you will want to use....

$('#StatesID').on('change', function(){
    countStates();
});

otherwise click does not fire if the user selects more that one option at a time.

Answer 2

Try this :

$(document).ready(function() {
    $('#StatesID').click(countStates);
});
