做东西时经常用到中国地区选择功能,于是从网上搜索一些中国地区js代码,然后给他引用到aspx页中,这也许您会碰到个问题:在html中测试一切正常,但是js文件嵌套到aspx文件中，就会出错!这个问题也困饶我n长时间,但是你只要用记事本打开.js后，另存一次，不过要注意的是：底下编码类型请选择：unicode
这样整个世界就和平拉! (注：该方法是小笨笨同学发现)
长话短说,咱开始讲经:
首先看效果:
一 .先准备个js文件,给他个美名为:area.js(并把他放到文件夹js下)js下载
area.js代码:
function Dsy()
{
this.Items = {};
}
Dsy.prototype.add = function(id,iArray)
{
this.Items[id] = iArray;
}
Dsy.prototype.Exists = function(id)
{
if(typeof(this.Items[id]) == "undefined") return false;
return true;
}
function change(v){
var str="0";
for(i=0;i<v;i++){ str+=("_"+(document.getElementById(s[i]).selectedIndex-1));};
var ss=document.getElementById(s[v]);
with(ss){
length = 0;
options[0]=new Option(opt0[v],opt0[v]);
if(v && document.getElementById(s[v-1]).selectedIndex>0 !v)
{
if(dsy.Exists(str)){
ar = dsy.Items[str];
for(i=0;i<ar.length;i++)options[length]=new Option(ar[i],ar[i]);
if(v)options[1].selected = true;
}
}
if(++v<s.length){change(v);}
}
}
var dsy = new Dsy();
dsy.add("0",["安徽","北京","福建","甘肃","广东","广西","贵州","海南","河北","河南","黑龙江","湖北","湖南","吉林","江苏","江西","辽宁","内蒙古","宁夏","青海","山东","山西","陕西","上海","四川","天津","西藏","新疆","云南","浙江","重庆"]);
dsy.add("0_0",["安庆","蚌埠","巢湖","池州","滁州","阜阳","合肥","淮北","淮南","黄山","六安","马鞍山","宿州","铜陵","芜湖","宣城","亳州"]);
dsy.add("0_0_0",["安庆市","怀宁县","潜山县","宿松县","太湖县","桐城市","望江县","岳西县","枞阳县"]);
dsy.add("0_0_1",["蚌埠市","固镇县","怀远县","五河县"]);
dsy.add("0_0_2",["巢湖市","含山县","和县","庐江县","无为县"]);
dsy.add("0_0_3",["池州市","东至县","青阳县","石台县"]);
dsy.add("0_0_4",["滁州市","定远县","凤阳县","来安县","明光市","全椒县","天长市"]);
dsy.add("0_0_5",["阜南县","阜阳市","界首市","临泉县","太和县","颖上县"]);
dsy.add("0_0_6",["长丰县","肥东县","肥西县"]);
dsy.add("0_0_7",["淮北市","濉溪县"]);
dsy.add("0_0_8",["凤台县","淮南市"]);
dsy.add("0_0_9",["黄山市","祁门县","休宁县","歙县","黟县"]);
dsy.add("0_0_10",["霍邱县","霍山县","金寨县","六安市","寿县","舒城县"]);
dsy.add("0_0_11",["当涂县","马鞍山市"]);
dsy.add("0_0_12",["灵璧县","宿州市","萧县","泗县","砀山县"]);
dsy.add("0_0_13",["铜陵市","铜陵县"]);
dsy.add("0_0_14",["繁昌县","南陵县","芜湖市","芜湖县"]);
dsy.add("0_0_15",["广德县","绩溪县","郎溪县","宁国市","宣城市","泾县","旌德县"]);
dsy.add("0_0_16",["利辛县","蒙城县","涡阳县","亳州市"]);
dsy.add("0_1",["北京"]);
