示例标记

<select multiple="multiple">
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  <option value="4">4</option>
  <option value="5">5</option>
</select>

示例jQuery

$('select').on('change',function() {
  alert('Changed!');
});

这是Chrome的错误吗？我试过searching,但没有遇到任何东西.

Here’s a fiddle
