我试过这个，但它只是重定向到页面而没有填充任何字段。
<DOCTYPE html>
<html>
<head>
<title>TEST</title>
<script>
window.onload = function() {
document.getElementById('loginForm').submit();
};
</script>
</head>
<body>
<form id="loginForm" action="URL of site" method="POST">
<input type=hidden name="username" value="moo"/>
<input type=hidden name="password" value="boo"/>
</form>
</body>
</html>
我的代码出了什么问题，我怎样才能实现目标？ 谢谢。
