function getSheng(){
var s =document.getElementById("sheng");
for(var v in shengArr){
s.add(new Option(v,v),null);
}
}
function getCity(){
var s =document.getElementById("sheng");
var c =document.getElementById("city");
var v=s.value;
c.options.length =0;
for(var i in shengArr[v]){
c.add(new Option(shengArr[v][i],shengArr[v][i]),null);
}
}
</script>
<!--页面加载时获取 省名-->
<body onload="getSheng()">
<!-- 改变省时匹配该省的城市名-->
省：<select id="sheng" onchange="getCity()">
<option>--请选择</option>
</select>

</body>
</html>
