        //使用HTML5 Web存储的localStorage和sessionStorage方式进行Web页面数据本地存储。
        //页面参考如下图，能将页面上的数据进行本地存储。并能读取存储的数据显示在页面上。
        var t1;
var t2;
var oStorage;
var oStorage;
function init() {//初始化t1，t2
            t1 = document.getElementById("t1");
            t2= document.getElementById("t2");
            sStorage= window.sessionStorage;
            lStorage= window.localStorage
        }
function saveSession() {
            sStorage.mydata= t2.value;
            t1.value+= "sessionStorage保存mydata:" + t2.value + "\n";
        }
function readSession() {
            t1.value+= "sessionStorage读取mydata:" + sStorage.mydata + "\n";
        }
function cleanSession() {
            t1.value+= "sessionStorage清除mydata:" + sStorage.mydata + "\n";
            sStorage.removeItem("mydata");
        }
function saveStorage() {
            lStorage.mydata= t2.value;
            t1.value+= "localStorage保存mydata:" + t2.value + "\n";
        }
function readStorage() {
            t1.value+= "localStorage读取mydata:" + lStorage.mydata + "\n";
        }
function cleanStorage() {
            t1.value+= "localStorage清除mydata:" + lStorage.mydata + "\n";
            lStorage.removeItem("mydata");
        }
