jQuery select2 get value of select tag?

Answer 1

See this fiddle.
Basically, you want to get the values of your option-tags, but you always try to get the value of your select-node with $("#first").val().

So we have to select the option-tags and we will utilize jQuerys selectors:

$("#first option").each(function() {
    console.log($(this).val());
});

$("#first option") selects every option which is a child of the element with the id first.
