Js 实现五级联动

js实现多级联动的方法很多,这里给出?种5级联动的例子,其实可以扩展成N级联动,在做项目的时候碰到了这样?个问题但是有不能从数据库中动态的加载这些选项,所以只有想办法从单个的页面着手来处理了,应为项目的表单是动态产生的,所以需要每个流程的设计过程中需要有单独的页面来处理,这样就决定了不能改变已有的业务逻辑来实现多级表单的联动。
Code如下:
<html>
<head>
<title>级联</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<style>
body,select
{
font-size:9pt;
font-family:Verdana;
}
a
{
color:red;
text-decoration:none;
}
a:hover
{
text-decoration:underline;
}
</style>
<SCRIPT LANGUAGE="JavaScript">
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))
{

for(i=0;i<ar.length;i++)options[length]=new Option(ar[i],ar[i]);

}
}
