城市类太大了,发不了。
我是把省、市、地区分别存在三个数据表中(我是新手,刚自己写的)

关于php+mysql+ajax省市区三级联动菜单,求帮助
基本思想就是:在JS动态创建select控件的option,通过Ajax获取在PHP从SQL数据库获取的省市区信息,代码有点长,但很多都是类似的,例如JS中省、市、区获取方法类似,PHP中通过参数不同执行不同的select语句。
index.html代码:
!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
""
html xmlns=""
head
title省市区三级联动/title
META http-equiv=Content-Type content="text/html; charset=gb2312"
script src="scripts/thumbnails.js" type="text/javascript"/script
/head
thumbnails.js代码:
window.onload = getProvince;
function createRequest() {//Ajax于PHP交互需要对象
try {
request = new XMLHttpRequest();//创建一个新的请求对象;
} catch (tryMS) {
try {
request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (otherMS) {
try {
request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (failed) {
request = null;
}
}
}
return request;
}
function sech(id) {//省市改变时触发,select的onchange事件
var aa = document.getElementById(id);
if(id=="sheng"){
getCity(aa.value);//这里aa.value为省的id
}
if(id=="shi")
{
getCounty(aa.value);//这里aa.value为市的id
}
}
function getProvince() {//获取所有省
request = createRequest();
if (request == null) {
alert("Unable to create request");
return;
}
var url= "getDetails.php?ID=0";//ID=0时传递至PHP时让其获取所有省
request.open("GET", url, true);
request.onreadystatechange = displayProvince; //设置回调函数
request.send(null); //发送请求
}
function getCity(id){//获取省对应的市
request = createRequest();
if (request == null) {
alert("Unable to create request");
return;
}
var url= "getDetails.php?ID=" + escape(id);
request.open("GET", url, true);
request.onreadystatechange = displayCity;
request.send(null);
}
function getCounty(id){//获取市对应的区
request = createRequest();
if (request == null) {
alert("Unable to create request");
return;
}
var url= "getDetails.php?ID=" + escape(id);
request.open("GET", url, true);
request.onreadystatechange = displayCounty;
request.send(null);
}
function displayProvince() {//将获取的数据动态增加至select
if (request.readyState == 4) {
if (request.status == 200) {
var a=new Array;
var b=request.responseText;//将PHP返回的数据赋值给b
a=b.split(",");//通过","将这一数据保存在数组a中
document.getElementById("sheng").length=1;
var obj=document.getElementById("sheng');
for(i=0;i
obj.options.add(new Option(a[i],i+1)); //动态生成OPTION加到select中,第一个参数为Text,第二个参数为Value值.

if (request.readyState == 4) {
if (request.status == 200) {
var a=new Array;
var b=request.responseText;
a=b.split(",");
document.getElementById("shi").length=1;//重新选择
document.getElementById("xian").length=1;//重新选择
if(document.getElementById("sheng").value!="province"){
var obj=document.getElementById('shi');
for(i=0;i
obj.options.add(new Option(a[i], document.getElementById("sheng").value*100+i+1)); //ocument.getElementById("sheng").value*100+i+1对应的是市的ID。

数据库设计,表格Province表,City表,County表。
要求:Province表需要id和name,id建议从1至34,例如北京id为1,广东id为2,以此类推;
City表需要id,name和cid,id为cid*100+1,cid为该市的上级,例如深圳的上级为广东省,cid为2的话,深圳的id就是201,以此类推。
County表需要id,name和cid,因为是三级的关系,id可以随意,建议从10001开始自增。cid为所在上级,例如宝安区的cid为201,龙岗区的cid也为201;

PHP 省市区写在一起 怎样截取成单个的
有3种方法:
1、手工一行一行的写成php代码
2、使用程序分析图一的数据,写入到数据库里,然后动态查询
3、使用程序分析图一的数据,写入到数据库里,动态生成图二的代码
怎么用php读取数据库方式动态生成省市县三级联动选择框
需要使用到ajax。到网上查下,一堆。代码是固定的。
数据库设置
id,area,areaname
1 210000 辽宁省
2 210100 沈阳市
3 210104 大东区
select name='area1' id='area1' onchange="get_area2(this.value);"
这里读取省的数据
$sql="select area,areaname from area where right(area,4)='0000'";
/select
select name='area2' id='area2 'onchange="get_area(this.value);"
这里根据ajax读取数据,开始的时候是空的
/select
select name='area' id='area'
这里根据ajax读取数据,开始的时候是空的
/select
方法:
1,首先写get_area2 的js 代码,这里就用到ajax读取,这里获取的数据是区域代码的前两位代码(比如:21)
这个在根据这个21的参数,读取表中相关的市,
$sql="select area,areaname from area where left(area,2)='21' and right(area,2)='00'";
这个语句读取出来21的市代码
2,同一读取出来区的代码
