在FireFox和Explorer中使用Cookie代碼但不使用Chrome

Question

以下cookie製作代碼適用於Firefox和Explorer，但不適用於Chrome。

我已設置警報以停止腳本並驗證是否按預期創建了新的Date（）對象。所有3個瀏覽器都表示正在創建新的Date（），並且按期望添加10分鐘到期。

流程：登錄頁面 - >

頁

這是登錄頁面的創建一個cookie代碼：

/* 
    Event handler for verify button click. 

    @param event is the event that triggered this function. 
*/ 
function checkUser(event){ 

    // interesting note: even though the button isn't of type submit, it submits the form. 
    // this prevents the form from being submitted: 
    event.preventDefault(); 

    // obtain user name from form 
    var name = this.form.userName.value; 

    // obtain password from form 
    var password = this.form.password.value; 

    // is the password valid? 
    if(isValidPassword(password)){ 

     // create new Date object for cookie's expiration 
     var expires = new Date(); 

     if(expires){ 
      alert(expires.toString()); 
     } 

     // increase expire time by 10 minutes 
     expires.setMinutes(expires.getMinutes() + 10); 

     alert(expires); // Firefox & Chrome show with additional 10 minutes. 

     // write userName cookie 
     document.cookie = "userName=" + encodeURIComponent(name) + 
      "; expires=" + expires.toUTCString(); 

     // write password cookie 
     document.cookie = "password=" +encodeURIComponent(password) + 
      "; expires=" + expires.toUTCString();  

     // password is valid, allow entry to private web page. 
     location.href = "project3.html"; 

    }else{ 
     // password was not valid 
     alert("Password must be at least 1 character in length."); 
     this.form.password.focus();   
    } 
} 

然後在放在location.href「project3.html」這樣的代碼，檢查cookie。警報（allCookies）彈出並在Firefox和Explorer中顯示Cookie，但在Chrome中完全空白; ，所以我立即被重定向回登錄頁面。這似乎表明，我的Cookie編寫代碼無法正常工作或Cookie在Chrome中被關閉？但是我選中了「Chrome內容設置」下的Chrome和單選按鈕「允許設置本地數據」。因此，這讓我想到我做了一些Chrome瀏覽器不喜歡的cookie製作的錯誤，您能否發現它並讓我知道問題是什麼？非常感謝。

// 
// Ensure user has a right to visit this web page. 
// 

//attach load event listener to window 
window.addEventListener('load', verifyPassword, false); 

// attach blur event listener to window 
window.addEventListener('blur', verifyPassword, false); 

/* 
    Event handler for window load event. Ensures user has proper credentials 
    via looking for password name:value pair held in document.cookie collection. 
*/ 
function verifyPassword(){ 

    // decode cookies 
    var allCookies = decodeURIComponent(document.cookie); 

    alert(allCookies); // Blank in Chrome; shows cookies in Firefox and Explorer. 

    var password; 

    // is the password cookie present? 
    if(hasCookie("password", allCookies)){ 

     // password cookie present, get password value 
     password = getCookie("password", allCookies);    

    }else{   
     // send user to login page 
     location.href = "project3_login.html"; 
    } 

    // password is present, is it valid? 
    if(isValidPassword(password)){ 
     // they get to stay  
     // cookie expires in... 
    }else{ 
     // send user to login page 
     location.href = "project3_login.html"; 
    } 
}

我是javascript的新手。我研究餅乾&在鉻上打破了我的頭。我的代碼在IE上正常工作。但不是在Chrome上。 Chrome說啓用了Cookie。但是，我不能寫出一個。版本38.0.2125.111如果你在chrome上進入「about」，你可以得到幫助。顯然這是一個問題。鉻以不同的方式處理曲奇。我不明白。我還沒有研究過它。希望我的指針有所幫助
