插件下载地址：http://www.jq22.com/jquery-info8054
引入JS包：
<script src="${pageContext.request.contextPath}/js/distpicker.data.js" charset="UTF-8"></script>
<script src="${pageContext.request.contextPath}/js/distpicker.js" charset="UTF-8"></script>
<script src="${pageContext.request.contextPath}/js/main.js" charset="UTF-8"></script>
<script src="${pageContext.request.contextPath}/js/jquery-1.11.1.min.js"></script>
页面：
<div data-toggle="distpicker" id="target">
<table width="100%" height="40" border="0" cellpadding="0" cellspacing="0">
<tr>
<td width="25%" class="put5" >
<select class="form-control" id="province1" data-province="河北省" style="height: 30px;"></select>
<label class="sr-only" for="province1">省</label>
</td>
<td width="25%" class="put5">
<select class="form-control" id="city1" name="cityName" data-city="${stu.cityName}" style="height: 30px;"></select>
<label class="sr-only" for="city1">市</label>
</td>
<td width="75%" class="put5">
<select class="form-control" id="district1" name="regionName" data-district="${stu.regionName}" style="height: 30px;"></select>
<label class="sr-only" for="district1">区(县)</label>
</td>
</tr>
</table>
</div>
需要注意的是：
data-toggle="distpicker" 一定要有
data-province="河北省" 设置默认值
name自己定义
