这个是从百度个人中心找到的省市区城市级联JS基础城市数据 http://pr.bdimg.com/static/princess/js/setting_basic_f2b6cf89.js 如果想直接使用,可以下载弄好的cityData.js,请稳步到代码片段。 jQuery PHP select id="prov" onchange="getCity(this.value);

如果想直接使用,可以下载弄好的cityData.js,请稳步到代码片段。 jQuery PHP
<select id="prov" onchange="getCity(this.value);"></select>
<select id="city" onchange="getTown(this.previousElementSibling.value, this.value);"></select>
<select id="town"></select>

<script type="text/javascript" src="cityData.js"></script>

<script type="text/javascript">
	var porv='',city='',town='';
	var $ = function (id){return document.getElementById(id);}
	var c = cityData();
	var lenP = c.length;
	for(i=0; i<lenP; i++){
		prov += '<option value="' + i + '">' + c[i].name + '</option>';	
	}
	$('prov').innerHTML = prov;
	var getCity = function (f){
		var lenC = c[f].sub.length;
		for(j=0; j<lenC; j++){
			city += '<option value="' + j + '">' + c[f].sub[j].name + '</option>';		
		} 
		$('city').innerHTML = city;
	}
	var getTown = function (t, m){
		var lenT = c[t].sub[m].sub.length; 
		for(k=0; k<lenT; k++){
			town += '<option value="' + k + '">' + c[t].sub[m].sub[k].name + '</option>';
