永泰城主题乐园在那:ASP.NET的问题，急，高分求救

<script language="javascript" type="text/JavaScript">
function check()
{
if(document.form2.username.value=="")
{alert("please write down the user ID");
document.form2.username.focus();
return false;
}
if(document.form2.pwd.value=="")
{alert("please write down the password");
document.form2.pwd.focus();
return false;
}
if(document.form2.spwd.value=="")
{alert("please sure the password");
document.form2.spwd.focus();
return false;
}
if(document.form2.spwd.value=document.form2.pwd.value) //应该是form2吧？
{alert("2次输入的密码不同");
return false;
}
if(document.form2.email.value=="")
{alert("please sure the password");
document.form2.spwd.focus();
return false;
}
//这个应该写进方法内部
document.form2.ctype.value="add";
document.form2.submit();
}
</script>
//另外，检查一下有无拼写错误

这个代码应该不能提交吧，代码有错
if(document.form1.spwd.value=document.form2.pwd.value)

应为!=

document.form2.ctype.value="add";
document.form2.submit();

应该放在函数体内

如果你的代码调用是在subit按钮上则最后句改成return true;

放在普通按钮或链接上则不用改

<script language="javascript" type="text/JavaScript">
function check()
{
if(document.form2.username.value=="")
{alert("please write down the user ID");
document.form2.username.focus();
return false;
}
if(document.form2.pwd.value=="")
{alert("please write down the password");
document.form2.pwd.focus();
return false;
}
if(document.form2.spwd.value=="")
{alert("please sure the password");
document.form2.spwd.focus();
return false;
}
if(document.form2.spwd.value!=document.form2.pwd.value)
{alert("2次输入的密码不同");
return false;
}
if(document.form2.email.value=="")
{alert("please sure the password");
document.form2.spwd.focus();
return false;
}

document.form2.ctype.value="add";
document.form2.submit();

}
