Answer 1

$("#selectID").val();

From the jQuery API documentation on the val() method:

The .val() method is primarily used to get the values of form elements. In the case of <select multiple="multiple"> elements, the .val() method returns an array containing each selected option.

Answer 2

You want to use the selected selector

http://api.jquery.com/selected-selector/

$("#selectID option:selected").each(function () {
            $(this).val(); //this is one of the selected values
          });

Answer 3

$("#selectID").val()返回以逗号分隔的所选值列表。
