Javascript 自动登录到站点

Javascript 自动登录到站点,javascript,html,Javascript,Html,我想能够自动登录到一个网站。为此，我保存了该站点登录页面的副本。然后我在这个副本上预先输入密码和用户名。此页面上有一个登录按钮。所以通常，在输入用户名和密码后，我需要点击这个按钮进入下一页。但我想自动完成这项工作。以下是源代码的相关部分： <html> <head> <meta http-equiv="imagetoolbar" content="no"> <link rel="SHORTCUT ICON" href="/favicon.ico">

请登录
姓名：
if（document.getElementById（'nameInput'）。值=“”）
{
document.getElementById（'nameInput'）.focus（）；
}
密码：
if（document.getElementById（'nameInput'）。值！=''）
{
document.getElementById（'pass'）.focus（）；
}

我试图做的是添加一个脚本，如

<SCRIPT LANGUAGE="JavaScript">document.getElementById('pass').value = CJMaker.makeString(document.getElementById('pass').value;</SCRIPT>

document.getElementById（'pass'）.value=CJMaker.makeString（document.getElementById（'pass'）.value；

同样的代码位于“FORM”块的“onsubmit”部分，但不起作用

你能帮我拿这个吗

提前感谢。

调用此代码

$('#nameInput').val('user name');
$('#pass').val('password');
$('#loginForm').submit();

尝试上面的代码自动登录。我想它会起作用。

添加

文档。getElementById（'loginForm'）。submit（）；

在事件

onLoad上的标记中
例如，
我通过简化解决了这个问题
<html>

<title>Login Page</title>

<body onload="document.getElementById('loginForm').submit();">

<form id="loginForm" method="post" name='login' action="http://localhost/_common/servlet/lvl5/login?language=en" onsubmit="document.getElementById('pass').value = CJMaker.makeString(document.getElementById('pass').value);" >

<input id="nameInput" type="text" value="Administrator" name="name" size="25" maxlength="80" tabindex="1" style="width:175px;">

<input type="password" value="" id="pass" name="pass"  autocomplete="off" size="25" maxlength="80" tabindex="1" style="width:175px;  ">

</form> 

</body>
</html>


登录页面
但它不起作用。
错误是什么？我想能够自动登录到站点：从哪里？浏览器？自定义应用程序？没有错误。我只是没有得到我想要的。当我用internet explorer打开存储在本地磁盘上的html文件时，我可以看到带有“用户名”和“密码”的页面输入正确。但如果不单击“登录”按钮，它将自动导航到下一页。我的意思是，我希望自动使用此按钮的相同功能，而不单击它。一个明智的网站将对所有表单使用CSRF令牌，这将使此方法无法工作。为什么不依赖现代浏览的本机密码管理器rs？在问题的任何部分中提到了jQuery？我还在html代码的末尾使用了“document.loginForm.submit（）；”。它也不起作用。我已经在使用下面这样的代码。它正在工作var inputs=''；inputs+=''；inputs+=''；$（''+inputs+''）。appendTo（'body'）。submit（）。remove（）；将
（表单结束标记）放在
标记和保存页面之后，document.getElementById（'loginForm'）.submit（）；
将起作用，我应该将“document.getElementById（'loginForm'）.submit（）放在哪里？”？我们即将解决此问题。现在我编辑了问题并提供了所有html代码。根据您的建议，它会尝试自动连接。这正是我想要的。但尽管用户名和密码正确，系统告诉我“它们不正确”。使用相同的凭据，当我使用“登录”按钮时，它会工作。请您再次签出所有代码，好吗？我的用户名为“管理员”，密码为空。顺便说一句，当我放入“”在之前，它尝试自动连接。但是，在之后，它无法工作。可能是您在打开和关闭html标记时犯了错误。请确保所有标记都正确结束，例如，
，
标记正确结束，并且您没有丢失任何标记。是的，此类型的代码当然可以很好地工作简单无误。但您的代码（您的问题）的唯一问题是介于
和
之间。是的，但我/我们找不到实际代码的问题：）
