From the jQuery documentation

.val()

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.

To select all options just use $("select option") or to specifically target multiple use @Josh's answer $("select[multiple] option");
