HTML学习笔记之三（localstorage的使用）

1.获取对象

var localstroage = window.localStorage;

2.存储值

localstroage.setItem("openid","ksjhfkjajkdfjkszdjfksad");
			localstroage.setItem("uid","10001");

3.获取值

var openid = localstroage.getItem("openid");

4.删除某个值

localstroage.removeItem("openid");

5.删除所有值

localstroage.clear();

6.遍历所有键值

localStorage.uid = 1;
localStorage.sex="nan";
localStorage.age = 23;
for ( var i = 0, len = localStorage.length; i < len; ++i ) {
    console.log( localStorage.key( i ) +":" + localStorage.getItem(localStorage.key( i ))  );
}
