ASP下批量删除数据的两种方法，里面也有删除附件的功能。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:
<!--#include file=conn.asp-->
<%'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>
