方法一：
复制代码 代码如下:
id=request.form("checkbox")
id=Split(id,",")
shu=0
for i=0 to UBound(id)
sql="select * from jiang_fname where id="&id(i)
set rs=conn.execute(sql)
if not rs.eof then
delete_file(rs("fname"))
end if
rs.close
set rs=nothing
sql="delete from jiang_fname where id="&id(i)
conn.execute sql,shu1
shu=shu+1
next
if shu>0 then
response.Write("<script>alert('删除成功');location.href='"&url&"';</script>")
else
response.write("<Script>alert('删除失败');javascript: history.back();</script>")
end if
conn.close
set conn=nothing
方法二：巧用in关键字实现数据的批量删除
managenews.asp
复制代码 代码如下:
<>
<%'数据库的连接文件我就不多说了%> <html>
<head>
<title>管理新闻</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<link rel="stylesheet" href="../index/style.css" type="text/css">
<script>
function del () //用于判断记录有没有选中的函数
{
var flag=true;
var temp="";
var tmp;
if((document.form1.answer.length+"")=="undefined") {tmp=1}else{tmp=document.form1.answer.length}
if (tmp==1){
if (document.form1.answer.checked){
flag=false;
temp=document.form1.answer.value
}
}else{
for (i=0;i<document.form1.answer.length;i++) {
if (document.form1.answer[i].checked){
if (temp==""){
flag=false;
temp=document.form1.answer[i].value
}else{
flag=false;
temp = temp +","+ document.form1.answer[i].value
}
}
}
}
if (flag){ alert("对不起，你还没有选择！")}
else{ name=document.form1.name.value
//alert(name)
if (confirm("确实要删除？")){
window.location="delnews.asp?id=" + temp;
}
}
return !flag;
}
</script>
</head>
<body>
<script language=Javascript>
function checkall(all)//用于判断全选记录的函数
{
var a = document.getElementsByName("answer");
for (var i=0; i<a.length; i++) a[i].checked = all.checked;
}
</script>

<%end if%>

delnews.asp文件
复制代码 代码如下:
<>

'Response.Write arrdel
sql="delete from news where id in ("&arrdel&")"
'Response.Write sql
conn.Execute sql
set conn=nothing
response.write"<SCRIPT language=JavaScript>alert('删除成功！');"
response.write"javascript: history.go(-1)</SCRIPT>"
response.end
%>
