   select.change(function () {      initSelect();    });  }); // $(".div-select-target").each}

如何使用：

第1步、引用CSS和JS：

<link type="text/css" href="~/Scripts/DivSelect/divSelect.css" rel="external nofollow" rel="external nofollow" rel="stylesheet" /><script type="text/javascript" src="~/Scripts/jquery-1.7.1.min.js"></script><script type="text/javascript" src="~/Scripts/DivSelect/divSelect.js"></script>

第2步、给select控件加上class="div-select-target" width="200"，其中class="div-select-target"是必须的，width="200"是可选的。完整HTML代码如下：

<link type="text/css" href="~/Scripts/DivSelect/divSelect.css" rel="external nofollow" rel="external nofollow" rel="stylesheet" /><script type="text/javascript" src="~/Scripts/jquery-1.7.1.min.js"></script><script type="text/javascript" src="~/Scripts/DivSelect/divSelect.js"></script><div style="border: solid 1px #f99; margin: 50px; padding: 50px;">  <select name="sel" class="div-select-target" width="200" >    <option value="1">中国</option>    <option value="2">美国</option>    <option value="3">法国</option>    <option value="4">英国</option>    <option value="5">俄罗斯</option>    <option value="6">德国</option>    <option value="7">韩国</option>    <option value="8">日本</option>    <option value="9">印度</option>    <option value="10">巴西</option>    <option value="11">意大利</option>    <option value="12">这个国家的名称很长很长很长很长很长很长很长很长</option>    <option value="13">瑞士</option>    <option value="14">越南</option>    <option value="15">缅甸</option>    <option value="16">泰国</option>    <option value="17">加拿大</option>    <option value="18" selected="selected">南非</option>    <option value="19">澳大利亚</option>    <option value="20">新西兰</option>    <option value="21">挪威</option>    <option value="22">巴勒斯坦</option>    <option value="23">以色列</option>    <option value="24">新加坡</option>    <option value="25">马来西亚</option>    <option value="26">波兰</option>    <option value="27">国家27</option>    <option value="28">国家28</option>    <option value="29">国家29</option>    <option value="30">国家30</option>    <option value="31">国家31</option>    <option value="32">国家32</option>    <option value="33">国家33</option>    <option value="34">国家34</option>    <option value="35">国家35</option>    <option value="36">国家36</option>    <option value="37">国家37</option>    <option value="38">国家38</option>  </select></div><div style="border: solid 1px #f99; margin: 50px; padding: 50px; margin-top: 700px; margin-bottom: 700px;">  <select name="sel" class="div-select-target" width="200" >    <option value="1">中国</option>    <option value="2">美国</option>    <option value="3">法国</option>    <option value="4">英国</option>    <option value="5">俄罗斯</option>    <option value="6" selected="selected">德国</option>    <option value="7">韩国</option>    <option value="8">日本</option>  </select></div>
