s.add(new Option(v,v),null);
}
}
function getCity(){
var s = document.getElementById("shen");
var c = document.getElementById("city");
var v = s.value;//省份的名称，也是数组中的键
c.options.length = 0;//把城市下拉框中的项清除
//循环把某一个省的城市加入到市的下拉框
for(var i in shenArr[v] ){
c.add(new Option(shenArr[v][i],shenArr[v][i]),null);
}
