我做到了我自己，這是js代碼為它“gracefulSession.js”并調用這個JavaScript在頁面你要去哪里嵌入HTML代碼..

function checkSessionStatus() {

var lStorage = getLocalStorage();

if (lStorage) {

//lStorage.setItem('poleTime',new Date());

var poleTime = lStorage.getItem("poleTime");

var parsedTime;

try {

parsedTime = new Date(poleTime);

} catch (e) {}

//alert(new Date()-parsedTime)

//alert(new Date())

//alert(parsedTime)

//3900000 = 1H5M

if (parsedTime && (new Date() - parsedTime) < 3900000) {

//alert('NCATCH'+parsedTime);

} else {

//alert('POINT');

poleSessionStatus();

}

}

}

function setlatestPoleTIme() {

//alert("SETTING POLE TIME");

var lStorage = getLocalStorage();

if (lStorage) {

lStorage.setItem('poleTime', new Date());

}

}

function setCheckSessionTimer() {

var lStorage = getLocalStorage();

var isLoggedOut = false;

if (lStorage) {

if (lStorage.getItem('isLoggedOut') == 'true') {

isLoggedOut = true;

}

}

//console.log('checkingIfLoggedOut');

if (!isLoggedOut) {

setTimeout("setCheckSessionTimer();", 5000);

//console.log("NOPT LO");

$('#LoggedoutMessage').hide();

checkSessionStatus();

} else {

setTimeout("setCheckSessionTimer();", 5000);

//console.log("KO");

//alert("You're Logged Out from other tab");

$('#LoggedoutMessage').show();

}

}

function logout() {

//alert("LOGGIN OUT")

var lStorage = getLocalStorage();

if (lStorage) {

lStorage.setItem('isLoggedOut', 'true');

}

}

function resetLoggedOutFLag() {

var lStorage = getLocalStorage();

if (lStorage) {

lStorage.removeItem('isLoggedOut');

}

}

function getLocalStorage() {

var storage, fail, uid;

try {

uid = new Date;

(storage = window.localStorage).setItem(uid, uid);

fail = storage.getItem(uid) != uid;

storage.removeItem(uid);

fail && (storage = false);

} catch (e) {}

return storage

}

現在，HTML代碼嵌入，

You have been logged out.

Please login to continue.

最后，你保持你的HTML，保持這段JavaScript代碼在它的上面嵌入腳本標簽：

function poleSessionStatus() {

jQuery.ajax({

type: 'POST',

data: '',

url: '',

success: function (data, textStatus) {

//setTimeout ("checkSession();", 5000);

},

error: function (XMLHttpRequest, textStatus, errorThrown) {

$('#LoggedoutMessage').show();

},

complete: function (XMLHttpRequest, textStatus) {

$.unblockUI();

}

});

}
