Question

I know one can get the value of the currently selected item like this:

var myListBoxItemText = $('#myListBox').val().toString();

But how do you change this value in the list box to something else?

Answer 1

Seeing your update in the comments, here’s an updated answer. Just use the :selected selector to filter the options inside of your select element to get the selected option.

To change a select element’s selected option’s value property:

 $('#myListBox option:selected').val('new value');

To change its display text:

 $('#myListBox option:selected').text('new text');
