这是一个选择省市区的控件。我在后台.cs页面里面provinceSelector页面里面想获取到这三个<select>标签的值，为什么找不到provinceSelector，citySelector，areaSelector，郁闷！请给位帮助！
[解决办法]
加上ranat="server"就能看到了。
<select id="provinceSelector" runat="server"></select>
或者
<select id="provinceSelector" name="provinceSelector" ></select>
后台通过Request["provinceSelector"]取值
