Answer 1

您必须具体说明要返回的元素的值。

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>

Answer 2

试试这个==＆gt;

alert($('#testselect option[disabled]:selected').val());

<script src="https://code.jquery.com/jquery-2.2.4.min.js"></script>
<select id="testselect">
  <option disabled>1</option>
  <option disabled>2</option>
  <option disabled selected>3</option>
</select>
