少部分手机浏览器对于COOKIE支持不够导致服务端无法读取session的解决方案

//定义json格式字符串
var userData = {
    name: "sankyu Name",
    account:"sankyu",
    level:1.
    disabled:true
};
//存储userData数据
localStorage.setItem("userData",JSON.stringify(userData));
//读取userdata数据并赋值给新变量newUserData
var userData = JSON.parse(localstorage.getItem("userData"));
//对userData内的数据设置新值
JSON.parse(localStorage.getItem("userData")).name = " new Sankyu Name";
userData.name = "new Sankyu Name";
//输出new Sankyu Name
alert(userData.name);
//输出sankyu Name
alert(JSON.parse(localstorage.getItem("userData")).name);
