    function getItems(){
        var data = JSON.parse(localStorage.getItem('userinfo'));
        console.log("name:"+data.name+'\r age:'+data.age+"\r home:"+data.home);
   //取数组 /* console.log("data:"+data);*/
    }

    //localStorage删除指定键对应的值
    function deleteItem(){
        window.localStorage.removeItem('userinfo');
        console.log(localStorage.getItem('userinfo'));
    }

IE下本地HTML网页直接打开不支持 localStorage技术，直接发布服务器可以。
