jquery load方法導(dǎo)致cookie失效的問題：Session already invalidated

需要免登陸進入頁面"${ctx}/target/page"
寫了一個jsp文件如下：

<head>
  <script>
    $(document).ready(function () {
        $("#mainForm").submit();
        $("#mainForm").hide();

        //這里試了好幾個方法，都不行
        //$("body").load("${ctx}/target/page");  //1
        //$(location).attr('href', "${ctx}/target/page");  //2
        $("mainFrame").attr('href', "${ctx}/target/page"); //3
        
    });
  </script>
</head>

<body>
  <iframe name="mainFrame" width="100%" height="100%" id="mainFrame"></iframe>
  <div>
   <form target="mainFrame" action="${ctx}/login" method="post" id="mainForm">
    <input type="hidden" id="username" name="username" value="xiaohong">
    <input type="hidden" id="password" name="password" value="hj8pw">
   </form>
  </div>
<body>

其中如果1,2,3三行代碼不用，頁面自動進入主界面，然后有一個連接指向"${ctx}/target/page"，點擊就能進到頁面，現(xiàn)在我上面的頁面想讓其自動進入這個頁面，結(jié)果發(fā)現(xiàn)不行，其中1,2偶爾能進去目標(biāo)頁面，但是大多數(shù)時候，session id 的cookie被沖刷替換掉了，導(dǎo)致訪問失敗，

而3則是停留在主界面

怎么回事啊？

涼心人

submit是需要時間,如果服務(wù)器端還沒有完成相應(yīng)的請求,這時候訪問受session保護頁面,肯定是沒有的,你可以試試ajax方式,在seccess時再執(zhí)行頁面加載, 或都簡單用setTimeout進行延時請求試試.

我以為

我的判斷是submit方法會導(dǎo)致頁面刷新，然后頁面不斷重復(fù)提交導(dǎo)致問題。

你的最終目的是什么呢？如果你是要做模擬登錄，建議用selenium
