高分求一个三级联动下拉框（省、市、地区）
在网上找了几个都不太理想
简单例子也可以
要求在FireFox下面可以正常使用
取值方便
不知道为什么我只能给100分如果对分数有要求解决后我可以转帐1000分之内
[解决办法]
看看这个行吗？

把电子书下载下来，里面有你需要的几个经典联动菜单例子，还有其他有用的资料

剩下的就自己搞定吧！！
[解决办法]
哈哈,我看了一下代码,这个问题也简单,只要在js文件里加上这些value:
dsy.add( "0_0_5 ",[ "阜南县 ", "01 ", "阜阳市 ", "02 ", "界首市 ", "03 ", "临泉县 ", "04 ", "太和县 ", "05 ", "颖上县 ", "06 "]);
然后
for(i=0;i <ar.length;i++){
options[length]=new Option(ar[i],ar[i]);
}
改成
for(i=0;i <ar.length;i++){
options[length]=new Option(ar[i],ar[++i]);
}
即可,ohoh~

jsp中下面代码:
TR>
<TD>
<bean:define id= "placeKb1List " name= "outputBean " property= "placeKb1Bean " type= "java.util.ArrayList " />
<html:select property= "placeKb1 " onchange= "setPlace(1) ">
<html:options collection= "placeKb1List " property= "placeKb1 " labelProperty= "placeKb1Name " />
</html:select>
</TD>
<TD> 省 </TD>
<TD>
<bean:define id= "placeKb2List " name= "outputBean " property= "placeKb2Bean " type= "java.util.ArrayList " />
<html:select property= "placeKb2 " onchange= "setPlace(2) ">
<html:options collection= "placeKb2List " property= "value " labelProperty= "label " />

</TD>
<TD> 市 </TD>

<html:select property= "placeKb3 ">
<html:options collection= "placeKb3List " property= "value " labelProperty= "label " />
</html:select>
</TD>
<TD> 县 </TD>
</TR>
====================================================================
placeKb1Bean,placeKb12Bean, placeKb123Bean都是java类,在java中查出来,放到数组中,然后根据省,调用JS,显示该省份的市,同样依次类推,希望能给你有所参考.具体比较简单.
