首先写一个js文件，areaLocation.js:
var
provinceArray=
new
Array()
provinceArray=[
{"pname":"江苏",
"country":[
{
"cname":"南京市",
"town":["玄武区","白下区","秦淮区","建邺区","雨花台","江宁区",
"六合区","溧水县","高淳县"]},
{
"cname":"南通市",
"town":["崇川区","港闸区","启东市","如皋市","通州市","海门市","海安县","如东县"]
},
{
"cname":"苏州市",
"town":["金阊区","沧浪区","平江区","虎丘区","吴中区","张家港","昆山市","吴江市","太仓市"]
}
]
},
{"pname":"上海",
"country":[
{
"cname":"上海市",
"town":["徐汇区","普陀区","杨浦区","虹口区","卢湾区","浦东区","黄浦区","长宁区","闸北区","静安区","闵行区","松江区"]
}
]
}
]
function
areaInitialize(){
province.length=1
for(var
i
=
0i<provinceArray.lengthi++){
var
pro
=
provinceArray[i].pname
province.options[province.length]
=
new
Option(pro,pro)
}
}
function
changeCLocation(id,city){
//alert(id)
city.length
=
0
if(id>0){
var
j=id-1
var
i
var
countrys
=
new
Array()
countrys
=
provinceArray[j].country
city.options[0]
=
new
Option('不限','')
for
(i=0i
<
countrys.length
i++){
var
cname
=
countrys[i].cname
city.options[city.length]
=
new
Option(cname,
cname)
}
changeTLocation(id,1,town)
}else
if(id==0){
city.length
=
0
town.length
=
0
city.options[city.length]
=
new
Option('不限','')
town.options[town.length]
=
new
Option('不限','')
}
}
function
changeTLocation(pid,cid,town){
//alert(cid)
var
countrys
=
new
Array()
var
towns
=
new
Array()
town.length
=
0
var
i
countrys
=
provinceArray[pid-1].country
areaId
=
countrys[cid-1].areaId
towns
=
countrys[cid-1].town
city.options[0]
=
new
Option('不限','')
town.options[0]
=
new
Option('不限','')
for
(i=0i
<
towns.length
i++){
var
tname
=
towns[i]
town.options[town.length]
=
new
Option(tname,tname)
}
town.options[0]
=
new
Option('不限','')
}
2.
再写一个html页面：
<!DOCTYPE
HTML
PUBLIC
"-//W3C//DTD
HTML
4.01
Transitional//EN">
<html>
<head>
<script
type="text/javascript"
></script>
<script
type="text/javascript">
window.onload=areaInitialize()
</script>
</head>
<body>
<select
size="1">
<option
value=0
selected>--请选择--</option>
</select>
<select
size="1"
>
<option
value=0
selected>--请选择--</option>
</select>
<select
size=1>
<option
value=0
selected>--请选择--</option>
</select>
</body>
</html>
你好 我只有中的 省市联动 ··贴上代码 供你做参考吧//省份数组
var shenArr=["请选择省份/城市","北京市","上海市","天津市","重庆市","香港特别行政区","澳门特别行政区","湖南","辽宁","河北","山东","河南","湖北","福建","四川","江西"]
//自定义下标（属性）
//shenArr["名称"]
shenArr["请选择省份/城市"]=["请选择城市/地区"]
shenArr["北京市"]=["北京市"]
shenArr["上海市"]=["上海市"]
shenArr["天津市"]=["天津市"]
shenArr["重庆市"]=["重庆市"]
shenArr["香港特别行政区"]=["香港特别行政区"]
shenArr["澳门特别行政区"]=["澳门特别行政区"]
shenArr["福建"]=["福州市","厦门市","泉州市","漳州市","南平市","三明市","龙岩市","莆田市"]
shenArr["湖南"]=["长沙市","株洲市","湘潭市","郴州市","益阳市","娄底市","衡阳市","常德市"]
shenArr["辽宁"]=["沈阳市","大连市","抚顺市","鞍山市","铁岭市","本溪市","丹东市","锦州市"]
shenArr["河北"]=["保定市","唐山市","邯郸市","邢台市","沧州市","衡水市","廊坊市","承德市"]
shenArr["山东"]=["济南市","青岛市","威海市","潍坊市","菏泽市","济宁市","莱芜市","烟台市"]
shenArr["河南"]=["洛阳市","焦作市","商丘市","信阳市","周口市","鹤壁市","安阳市","濮阳市"]
shenArr["湖北"]=["武汉市","荆门市","汉口市","咸宁市","襄樊市","荆州市","黄石市","孝感市"]
shenArr["江西"]=["南昌市","赣州市","上饶市","宜春市","吉安市","抚州市","萍乡市","九江市"]
$.each(shenArr,function(i,val){
//添加下拉项
$("select[name=sheng]").append("<option value='"+val+"'>"+val+"</option>")
})
//市级下拉框绑定
$("select[name=sheng]").change(function(){
var index=$(this).val()
var shiArr=shenArr[index]
$("select[name=shi]").empty()
$.each(shiArr,function(i,val){
//添加下拉项
$("select[name=shi]").append("<option value='"+val+"'>"+val+"</option>")
})
})
<select name="sheng"></select> 
<select name="shi">
<option>请选择城市/地区</option>
</select>
