localstorage详解

1. 获取对象 [javascript] view plain copyvar localstroage = window.localStorage;

2.存储值 [javascript] view plaincopy localstroage.setItem('openid','ksjhfkjajkdfjkszdjfksad'); localstroage.setItem('uid','10001');

3.获取值 [javascript]view plain copy var openid = localstroage.getItem('openid');

4.删除某个值[javascript] view plain copy localstroage.removeItem('openid');

5.删除所有值 [javascript] view plain copy localstroage.clear();

6.遍历所有键值[javascript] view plain copy 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 )) );}注意：1.如果不主动删除 localstorage 是不会自动清空的 不会像cookie一样清除 2. localstorage 几乎支持大部分浏览器 不用考虑IE8 的问题 大小为 5M
