1、判断浏览器是否支持 localStorage 属性

if (window.localStorage) {    alert('This browser supports localStorage');} else {    alert('This browser does NOT support');}

2、localStorage 的存储格式都是字符串，任何其他类型都会转成字符串存储。

3、存值

localstroage.setItem('uid','10001');

4、取值

var uid = localstroage.getItem('uid');

5、删除某个值

localstroage.removeItem('uid');

6、删除所有值

localstroage.clear();

7、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 ))  );}

8、jQuery操作Cookies
