用localStorage来存储数据的一些经验

localStorage存储方法

localStorage.name = localStorage["name"]=‘vanida‘；localStorage.setItem("name","vanida");//这三种设置值方式是一样的；

localStorage获取值方法
var name = localStorage["name"] = localStorage.name＝ localStorage.getItem("name");//这三种获取值方式是一样的；

localStorage清值方法
localStorage.removeItem("name");或者localStorage.name＝‘‘;//清除name的值

localStorage只能存储字符串，如果需要存储对象，首先要转化为字符串。利用JSON.stringify()；

例子：

var person = {name:"vanida","sex":"girl","age":25};localStorage.setItem("person",JSON.stringify(person));

// localStorage.person="{"name":"vanida","sex":"girl","age":25}"

然后取出person的对象你可以用JSON.parse();

例子：

person = JSON.parse(storage.getItem("person"));

// {name: "vanida", sex: "girl", age: 25}
