Question

jsp提交表单后javascript进行验证，发现验证不通过了，也弹出alert了，但信息依然提交了，求解决方法。

<form id="editForm" name="editForm" method="post" action="edit_Judge.jsp">
<center>
<table>
<tr>
<td colspan="2">
请输入旧密码:
<input type="password" name="oldPsw"></input>
</td>
</tr>
<tr>
<td colspan="2">
请输入新密码:
<input type="password" name="newPsw"></input>
</td>
</tr>
<tr>
<td colspan="2">
请确认新密码:
<input type="password" name="newPsw2"></input>
</td>
</tr>
<tr>
<td>
<input name="Edit" type="submit" value="确认修改" onclick="return (check())"></input>
</td>
<td>
<input name="eReset" type="reset" value="重置"></input>
</td>
</tr>
</table>
</center>
</form>

js的代码如下
function check(){
if(editForm.oldPsw.value==""){
alert("请输入旧密码！");
editForm.username.focus();
return false;
}
if(editForm.newPsw.value==""){
alert("请输入新密码");
editForm.userpsw.focus();
return false;
}
if(editForm.newPsw2.value!=editForm.newPsw.value){
alert("密码不匹配！");
editForm.userpsw.focus();
return false;
}
}
}

<input name="Edit" type="submit" value="确认修改" onclick="return (check())"></input>
这句中修改下，改成return check()或者直接改成check()

<form id="editForm" name="editForm" method="post" action="edit_Judge.jsp">
这句中加一个，改成下面这样：
<form id="editForm" onsubmit="return check()" name="editForm" method="post" action="edit_Judge.jsp">
