<script>
var Provinces=new Array("江苏","浙江","内蒙古")
var Citys=new Array();
Citys[0]=new Array("南京","苏州","无锡");
Citys[1]=new Array("杭州","温州","宁波");
Citys[2]=new Array("呼和浩特","包头");
var p="<select id='province'/>"
var c="<select id='city'/>";
var place="<div id='city'></div>"
</script>
在页面中输出place层,并将该层的背景通过javascript设置成蓝色
