<input type="submit" value="确定" onClick="return f1()">
这样写不管验证对错都会跳到login.do
帮看看吧
--------------------编程问答-------------------- <form action="login.do" name="form1" onsubmit="return f1()">
<input type="text" name="email">
<input type="submit" value="确定">
</form>
--------------------编程问答-------------------- 1楼正解!
还有楼主这个地方貌似写错了
return flase;---->return false;
--------------------编程问答--------------------
正解
或者
<input type="button"
JS里面
if(true){
form1.submit();
} --------------------编程问答-------------------- 1楼解决了 --------------------编程问答-------------------- <html>

submit直接提交了 有事件多用button在func中提交 --------------------编程问答-------------------- submit是什么 是不管怎样都提交，把submit换成button就ok 了 --------------------编程问答-------------------- 这个应该用AJAX吧 不刷新吧 --------------------编程问答-------------------- return flase;应该是
return false;

1楼的可以，3楼的思路大概对。
最好采用js提交表单，这样的好处，防止网页后退时候，重复提交表单。
补充：Java , Java EE
