Html5中localStorage，sessionStorage用法

   详细介绍:http://www.cnblogs.com/erdeni/p/WebStorage.html

/* * 将数据存储到localStorage中 */jQuery.fn.addHashMapToLocalStorage=function(key,value){         if(window.localStorage){                    localStorage.setItem(key,value);         }else{                   $().Toast("浏览器不支持localStorage");         }}

/* * 获取localStorage中的数据 */jQuery.fn.getHashMapToLocalStorage=function(key){         if(window.localStorage){                    return localStorage.getItem(key);         }else{                   $().Toast("浏览器不支持localStorage");         }} 

用法：

$().addHashMapToLocalStorage("userName",userName);$().addHashMapToLocalStorage("password",password); $("#input_userName").val($().getHashMapToLocalStorage("userName"));$("#input_password").val($().getHashMapToLocalStorage("password"));

sessionStorage用法类似
