两个按钮的事件怎么都不能响应呢?
比如密码或是用户名为空的时候，单击按钮都没有提示对话框弹出啊！
不知道是什么原因了列，能帮我看看么 。。。

主要代码如下！
<script language="javascript">
function CheckData()//表单数据检查函数
{
    var errMsg = "";

    //用户名、密码、验证都不能为空
    if(form1.Name.value == "")
        errMsg = "请输入用户名"
    else if(form1.passwd.value == "")
        errMsg = "请输入密码"        
    if(errMsg == "")
        return true;
    else
    {
        window.alert(errMsg);//提示错误信息
        return false;
    }
}
function SubmitForm()
{
    //在提交表单时检验数据有效性
    if(CheckData())
        userlogin.submit();
}
</script>

           <table width="459" border="0" align="left" cellpadding="0" cellspacing="2">
                                       
        <form  method="post" name="form1" id="userlogin" action="checkpwd.asp">
                                      <input type="hidden" name="formhash" value="b639ce54" />
                                      <input type="hidden" name="referer" value="index.php" />
                                      <tr>
                                        <td height="24" class="STYLE4">
            <%
                                        
            If Session("IsPassed") = true Then
            %>
            登陆成功！ <% =Session("Name")%>，欢迎您的到来！

            <div align="right"><a href="logout.asp">退出登陆</a></div>
            <%else%>
            <%
response.Write"<div align='left'> 用户名:<input name='Name'type='text'onblur='this.style.background='#FFF';' onfocus='this.style.background='#f4f4f4';'  size='8' maxlength='16' width='50' value='"
%>
<%
    '检查Cookies，如果存在帐号信息，则填写文本框
    If (Request.Cookies("Name") <> EMPTY)  Then
        Response.Write(Request.Cookies("Name"))
    Else
        Response.Write("")
    End If
%>
<%
response.Write"' />"
response.Write" 密码:"
response.Write"<input name='passwd' type='password'  onblur='this.style.background='#FFF';' onfocus='this.style.background='#f4f4f4';' size='8' maxlength='16' width='50' value='"

        Response.Write(Request.Cookies("Password"))
    Else
        Response.Write("")
    End If
%>
<%
response.Write"' /> "

response.Write"<input name='btnSub' type='button' class='STYLE1' style='BORDER-RIGHT: 1px solid; BORDER-TOP: 1px solid;      BORDER-LEFT:   1px solid; BORDER-BOTTOM: 1px solid'  value='登录'  onclick='SubmitForm()'/>"
response.Write"  "
response.Write"<input name='button' type='button' class='STYLE5' style='BORDER-RIGHT: 1px solid; BORDER-TOP: 1px solid; BORDER-LEFT: 1px     solid; BORDER-BOTTOM: 1px solid' value='注册' onclick='window.location.href='landing_1.asp'' />"   
response.Write" </div>"
 %>
<%end if%></td>
                                      </tr>
                                    </form>
                                      </table>

谢谢版主！
那请问一下，我上边所写的为什么会错误呢！
不是说 在response.write""这条语句内的双引号全都要改成单引号么

恩  大概了解了
感谢yms123版主和anlige的精彩答复！
