我的任务
分享一个页面要放两个三级联动下拉框
是省市县的三级联动。
但在一个页面上需要两个，如下：
出生省，出城城市，出生县
现居省，现居城市，现居县。
我下载的三级联动，只放一个可以正常运行，同事放两个就有错。请问应该如何修改。
一个三级联动的代码如下：
<!--
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",["北京","安徽","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",["北京"]);
dsy.add("0_0_0",["北京市","东城","西城","崇文","宣武","朝阳","丰台","石景山","海淀","门头沟","房山","通州","顺义","昌平","大兴","平谷","怀柔","密云","延庆"]);
dsy.add("0_29_9",["舟山市","岱山县","嵊泗县"]);
dsy.add("0_29_10",["常山县","江山市","开化县","龙游县","衢州市"]);
dsy.add("0_30",["重庆"]);
dsy.add("0_30_0",["城口县","大足县","垫江县","丰都县","奉节县","合川市","江津市","开县","梁平县","南川市","彭水苗族土家族自治县","荣昌县","石柱土家族自治县","铜梁县","巫山县","巫溪县","武隆县","秀山土家族苗族自治县","永川市","酉阳土家族苗族自治县","云阳县","忠县","重庆市","潼南县","璧山县","綦江县"]);
