需要免登陆进入页面"${ctx}/target/page"
写了一个jsp文件如下：
<head>
<script>
$(document).ready(function () {
$("#mainForm").submit();
$("#mainForm").hide();
//这里试了好几个方法，都不行
//$("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="${ctx}/login" method="post" id="mainForm">
<input type="hidden" id="username" name="username" value="xiaohong">
<input type="hidden" id="password" name="password" value="hj8pw">
</form>
</div>
<body>
其中如果1,2,3三行代码不用，页面自动进入主界面，然后有一个连接指向"${ctx}/target/page"，点击就能进到页面，现在我上面的页面想让其自动进入这个页面，结果发现不行，其中1,2偶尔能进去目标页面，但是大多数时候，session id 的cookie被冲刷替换掉了，导致访问失败，
后台报错：

而3则是停留在主界面
怎么回事啊？
java
submit是需要时间,如果服务器端还没有完成相应的请求,这时候访问受session保护页面,肯定是没有的,你可以试试ajax方式,在seccess时再执行页面加载, 或都简单用setTimeout进行延时请求试试.
