localStorage.setItem("key","value");//存储变量名为key，值为value的变量
localStorage.key = "value"//存储变量名为key，值为value的变量
 
localStorage.getItem("key");//获取存储的变量key的值www.it165.net
localStorage.key;//获取存储的变量key的值
localStorage.removeItem("key")//删除变量名为key的存储变量

var data= {"id":id,"name":name};//要存储的json对象
var selectCity=JSON.stringify(data);//将json对象转化成字符串
 localStorage.setItem("ffan_selectCity",selectCity);//把选择的数据存储在localstorage中

//取数据如下
var currentCity=localStorage.getItem("ffan_selectCity");
if(t.currentCity){
     var item=JSON.parse(t.currentCity);
     console.log("id="+item.id+",name="+item.name);
