Answer 2

You have to be specific about value of which element to return.

alert($("#testselect option:selected").val());

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<select id="testselect">
  <option disabled>1</option>
  <option disabled>2</option>
  <option disabled selected>3</option>
</select>
