这是网上找的地址联动下拉菜单的JS代码，我想实现的是S1为下拉选择菜单，在S1选择相应省后，S2文本的形式显示全部对应的市，S3默认显示S2的第一个选项对应的全部县，这种联动不知道可不可以通过以上方式实现啊，谢谢各位指教。
效果有点同51job的地址选择

谢谢的你答案，由于对JS确实不懂，你那个也是定义成三个下拉菜单的，可能是我没有说明白
s1 在下拉中选择之后（如：选择了四川）
S2现在全部的对应地址，（显示：成都 德阳 资阳 等等）
S3在S2没有选择的情况下，默认显示S2第一个市对应的县（如：青羊区 金牛区 成华区 等等），在S2选择变动了之后在对应的改变S3中的县

很好的例子啊

3个级联我还没用过。。不过2个级联的倒是经常用到！
用数组试试！
2个级联我就是用数组的

//定义数组
var zhengjian = new Array();
//将数组的元素再设置为数组
zhengjian["身份证"] = new Array("第一代身份证","第二代身份证","临时身份证","暂住证");
zhengjian["军官证"] = new Array("士官证","士兵证");
zhengjian["护照"] = new Array("因私护照","因公护照","公务护照");
//关闭下拉列表 。。加载数据
function selects()
{
document.form.select2.options.length=0;
//获取 选择的下标
var index = document.form.select1.options.selectedIndex;
//获取选中的项
var values = document.form.select1.options[index].innerText;

if(values!="请选择证件类型")
{
//循环添加数据到下拉框中
for(var j=0;j<zhengjian[values].length;j++)
{
document.form.select2.options.add(new Option((zhengjian[values])[j],j));
}
}
}
