使用DW用ASP+ACCESS编写目录树 时间：2004/11/7 2:32:00来源：本站整理作者：蓝点我要评论(0)

　　　　　　　　　　　　

　　　　　　　　　　　　利用ACCESS创建数据库listBase.mdb:
　　数据表：listTable
　　数据字段：listId listName listInfo parentId

　　连接方法：

<%
    dim sConn,sConnStr,sSql
    sConnStr="DRIVER={Microsoft Access Driver (*.mdb)};dbq=" & server.mappath("listBase.mdb")
    set sConn=server.createobject("adodb.connection")
    sConn.open sConnStr
%>

　　把以上代码保存成文件：initialize.asp

　　下面这段程序代码是用来显示目录树用的，保存成文件：inc.asp

<%
response.write("

" & chr(13))
response.write("" & chr(13)&"" & chr(13))
response.write("" & chr(13) & "" & chr(13) & "" & chr(13) & "

" & chr(13) & "")
response.write("" & chr(13) & "" & chr(13) & "" & chr(13))
response.write("" & chr(13))
response.write("" & chr(13))
response.write("

根节点

添加

" & chr(13))
'此处调用显示目录树的递归函数
listChild(0)
response.write("

" & chr(13))

'下面代码为显示目录树最关键的函数，使用了递归方法（很多象这样类型的都是用递归来做的。）
function listChild(id)
dim sRec,sSql,sNum,sTmp
set sRec=server.createobject("adodb.recordset")
sSql="select listId,listName,listInfo,parentId from listTable where parentId=" & id
sRec.open sSql,sConn,3,1
if not sRec.eof then
sNum=1
response.write("

" & chr(13))
while not sRec.eof
sTmp=sConn.execute("select count(listId) as countSub from listTable where parentId=" & sRec("listId"))
if sTmp("countSub")>0 then
response.write("" & chr(13))
if sNum=sRec.recordcount then
response.write("" & chr(13))
else
response.write("" & chr(13))
end if
response.write("" & chr(13) & "" & chr(13))
response.write("")
if sNum=sRec.recordcount then
response.write("" & chr(13))
else
response.write("" & chr(13))
end if
response.write("" & chr(13) & "" & chr(13))
else
response.write("" & chr(13))
if sNum=sRec.recordcount then
response.write("" & chr(13))
else
response.write("" & chr(13))
end if
response.write("" & chr(13) & "" & chr(13))
end if
sRec.movenext
sNum=sNum+1
wend
response.write("

" & chr(13) & "" & chr(13))
response.write("" & chr(13) & "" & chr(13) & "" & chr(13))
response.write("" & chr(13) & "" & chr(13) & "" & chr(13) & "

" & server.HTMLEncode(sRec("listName")) & "

response.write("" & chr(13) & "" & chr(13) & "" & chr(13))

end if
sRec.close '关闭记录集
set sRec=nothing '关闭记录集
end function
sConn.close '关闭数据库链接
set sConn=nothing '关闭数据库链接
%>

下面这是调用页代码，保存成index.asp

<%@LANGUAGE='VBSCRIPT' CODEPAGE='936'%>

目录树

下面是提交信息处理页的代码，保存为disp.asp

<%
function checkstr(str)
str=replace(str,"'","''",1,-1,1)
checkstr=str
end function

dim disp,parentId,listName,listInfo
disp=request.QueryString("disp")
parentId=request.QueryString("parentId")
select case disp
case "add"
listName=checkstr(left(request.QueryString("listName"),10))
listInfo=checkstr(left(request.QueryString("listInfo"),50))
if listName="" then listName="空白节点"
if listInfo="" then ListInfo="此节点在添加入未填写内容"
sSql="insert into listTable (listName,listInfo,parentId) values('" & listName & "','" & listInfo & "'," & parentId & ")"
case "edit"
listName=checkstr(left(request.QueryString("listName"),10))
listInfo=checkstr(left(request.QueryString("listInfo"),50))
if listName="" then listName="空白节点"
if listInfo="" then listInfo="此节点在添加入未填写内容"
sSql="update listTable set listName='" & listName & "',listInfo='" & listInfo & "' where listId=" & parentId
case "del"
sSql="delete from listTable where listId=" & parentId & " or parentId=" & parentId
end select
sConn.execute sSql,,1
response.redirect("index.asp")
%>

　　以上代码保存成的文件放在同一目录下面（在这里我们称为根目录）。
　　在根目录下新建一个CSS目录.
　　下面为CSS定义，保存成css.css文件，放在CSS目录下。注：有一两个样式是不要的，我没删

}

　　另在根目录下建一个IMAGES目录。用来放那些文件夹样子的小图。
