这是使用QQ网站用的js来实现省市区三级联动的。引用非常方便
前台：
<title>QQ JS省市区三级联动</title><!---ecms 直接使用QQ的省市区数据 --><!---ecms <script type=<span>"</span><span>text/javascript</span><span>"</span> src=<span>"</span><span>http://ip.qq.com/js/geo.js</span><span>"</span>></script>--><script type=<span>"</span><span>text/javascript</span><span>"</span> src=<span>"</span><span>geo.js</span><span>"</span>></script><body >"</span><span>setup();preselect('陕西省');promptinfo();</span><span>"</span>> <<span>select</span><span>class</span>=<span>"</span><span>select</span><span>"</span> name=<span>"</span><span>province</span><span>"</span> id=<span>"</span><span>s1</span><span>"</span>> </<span>select</span>> <<span>select</span><span>class</span>=<span>"</span><span>select</span><span>"</span> name=<span>"</span><span>city</span><span>"</span> id=<span>"</span><span>s2</span><span>"</span>> </<span>select</span>> <<span>select</span><span>class</span>=<span>"</span><span>select</span><span>"</span> name=<span>"</span><span>town</span><span>"</span> id=<span>"</span><span>s3</span><span>"</span>> </<span>select</span>> <input id=<span>"</span><span>address</span><span>"</span> name=<span>"</span><span>address</span><span>"</span> type=<span>"</span><span>hidden</span><span>"</span> value=<span>""</span> /> "</span><span>alert(document.getElementById('address').value); return false;</span><span>"</span> type=<span>"</span><span>submit</span><span>"</span> value=<span>"</span><span>提交</span><span>"</span> /> <script><span>//</span><span>这个函数是必须的，因为在geo.js里每次更改地址时会调用此函数</span><span>function promptinfo(){ </span><span>var</span> address = document.getElementById(<span>'</span><span>address</span><span>'</span><span>); </span><span>var</span> s1 = document.getElementById(<span>'</span><span>s1</span><span>'</span><span>); </span><span>var</span> s2 = document.getElementById(<span>'</span><span>s2</span><span>'</span><span>); </span><span>var</span> s3 = document.getElementById(<span>'</span><span>s3</span><span>'</span><span>); address.value </span>= s1.value + s2.value +<span> s3.value;}</span></script>
后台用的是js。
