首先感谢您抽出时间。我真的是编程新手所以我收到了的消息
login.do:34 Uncaught TypeError: Cannot set property 'action' of null
at login_ok (login.do:34)
at HTMLInputElement.onclick (login.do:245)
login_ok @ login.do:34
onclick @ login.do:245
问题在于；动作"；不起作用，我不知道为什么。它是关于登录的。非常感谢。
<script type="text/javascript">
function login_ok(f) {
f.action = "login_ok.do";
f.submit();
if (document.getElementById("log_id").value != document
.getElementById("hidden1").value) {
alert("WRONG ID.");
}
if (document.getElementById("login_pw").value != document
.getElementById("hidden2").value) {
alert("WRONG PASSWORD.");
}
}
function join_go() {
location.href = "join.do";
}
function findidpw_go() {
location.href = "findidpw.do";
}
</script>
<input type="button" value="LOGIN" onclick="login_ok(this.form)">
有人让我上传更多的代码嗯，我不知道如何上传代码所以我把所有东西都放进去了感谢您理解

您的jsp中没有form标记。
