Answer 1

我来抢个沙发，助人为乐嘛：给你写了2个验证的函数：
<script language="javascript">
<!--
function Check()
{
if (form1.PHONE1.value=="")
{
alert("请输入联系电话1")
document.form1.PHONE1.focus();
return false
}
if (form1.PHONE2.value=="")
{
alert("请输入联系电话2");
document.form1.PHONE2.focus();
return false
}
var num = document.form1.QQ_NUM.value;
if (num!=""&&!num.match(/^(\d)+$/))
{
alert ("请输入QQ 号码,而且QQ只能是数字！")
return false;
}
if (form1.ADDRESS.value=="")
{
alert("请输入到住 址");
document.form1.ADDRESS.focus();
return false
}
if (form1.CONNECTPERSON.value=="")
{
alert("紧急联系人")
document.form1.CONNECTPERSON.focus();
return false
}
if (form1.RELATION.value=="")
{
alert("与您的关系");
document.form1.RELATION.focus();
return false
}
if (form1.PERSONPHONE.value=="")
{
alert("联系电话")
document.form1.PERSONPHONE.focus();
return false
}
return true
}
//-->
</script>
<!--------------------用法：将以上代码拷贝到</head>之前，在你的表单里民加句<Form onSubmit="retrun Check();">---------------------->

下面还要在提交表单的时候做ASP验证：
<%
'错误提示代码
Sub Alert(Msg)
Response.Write("<script>alert('"& Msg &"');history.go(-1);</script>")
Response.End()
End Sub

'定义变量
Dim PHONE1,PHONE2,QQ_NUM,ADDRESS,CONNECTPERSON,RELATION,PERSONPHONE
PHONE1=Trim(Request.Form("PHONE1"))
PHONE2=Trim(Request.Form("PHONE2"))
QQ_NUM=Trim(Request.Form("QQ_NUM"))
ADDRESS=Trim(Request.Form("ADDRESS"))
CONNECTPERSON=Trim(Request.Form("CONNECTPERSON"))
RELATION=Trim(Request.Form("RELATION"))
PERSONPHONE=Trim(Request.Form("PERSONPHONE"))

'对变量进行判断是否为空,下面的
If PHONE1 = "" Then
Alert "对不起，联系电话1不能为空！"
FoundErr =True
End If
If PHONE2 = "" Then
Alert "对不起，联系电话2不能为空！"
FoundErr=True
End If
If IsNumeric(QQ_NUM)=False Then
Alert "对不起，QQ号码不能为空而且只能为数字！"
FoundErr = True
End If
If ADDRESS = "" Then
Alert "对不起，联系地址不能为空！"
FoundErr = True
End If
If CONNECTPERSON = "" Then
Alert "对不起，紧急联系人不能为空！"
FoundErr = True
End If
If RELATION= "" Then
Alert "对不起，与您的关系不能为空！"
FoundEr r= True
End If
If PERSONPHONE = "" Then
Alert "对不起，联系电话不能为空！"
FoundErr = True
End If

'在对表单判断完后现在就可以写入数据库了
If FoundErr <> True Then
Set Rs=SerVer.CreateObject("Adodb.recordset")
SQL="Select * From xxx "
Rs.open SQL,conn,1,3
Rs.addnew()
rs("PHONE1")=PHONE1
rs("PHONE2")=PHONE2
rs("QQ_NUM")=QQ_NUM
rs("ADDRESS")=ADDRESS
'.....略
