如何使用：
第1步、引用CSS和JS：
<link type="text/css" href="~/scripts/pSelect/pSelect.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/pSelect/pSelect.js"></script>
登录后复制
第2步、给select控件加上class="p-select-target" width="200"，其中class="p-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/pSelect/pSelect.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/pSelect/pSelect.js"></script>
<p style="border: solid 1px #f99; margin: 50px; padding: 50px;">
<select name="sel" class="p-select-target" width="200" >
<option value="1">中国</option>
<option value="2">美国</option>
