使用ASP实现网站的目录树
数据库结构(共使用了两个表) 1。tblCategory 字段名 类型 Root binary 说明树关或开(目录的根) ID 自动编号 关键字 Sort integer 识别该字段内容的整数(如果root是开状态sort为0)表示显示的目录的顺序 Name text(255)可以包含html中的标识符 HREF text(255) 允许空
2。tblPages ID 自动编号 Sort integer 关键字 Name text(255) HREF text(255)
3.default.htm <html> <head> <title>javascript Tree Control Template</title> </head> <frameset cols=""210,*""> ?<frame src=""tree.asp"" name=""TOC""> ?<frame src=""main.htm"" name=""basefrm""> </frameset> </html>
4.main.htm <head><title></title></head> <body> <h2>Start Page</h2> </body> </html>
5.tree.asp Set conn = Server.CreateObject(""ADODB.Connection"") Set Rs = Server.CreateObject(""ADODB.Recordset"") conn.open ""DRIVER=Microsoft Access Driver (*.mdb);DBQ="" & Server.MapPath(""toc.mdb"")
strsql = ""SELECT tblCategory.Root, tblCategory.[ID], tblCategory.Sort AS CatSort, tblPages.sort AS LinkSort, tblCategory.[Name] AS CatName, tblCategory.HREF AS CatURL, tblPages.[Name] AS LinkName, tblPages.href AS LinkURL FROM tblCategory LEFT JOIN tblPages ON tblCategory.[ID] = tblPages.[ID] ORDER BY tblCategory.root ASC, tblCategory.Sort, tblPages.sort""
rs.open strsql, conn, 2, 2
if not rs.eof then rs.movefirst currentID = """" %> <html> <head> <link rel=""stylesheet"" href=""ftie4style.css""> <!-- Infrastructure code for the tree --> <script src=""ftiens4.js""></script> <!-- Execution of the code that actually builds the specific tree --> <script> USETEXTLINKS = 1 <% Do While Not Rs.EOF If Rs(""Root"") = True Then %> foldersTree = gFld(""<%= Rs(""CatName"") %>"", ""<%= Rs(""CatURL"") %>"") <% Else %> aux1 = insFld(foldersTree, gFld(""<%= Rs(""CatName"") %>"", ""<%= Rs(""CatURL"") %>"")) <% currentID = Rs(""ID"") savedID = Rs(""ID"") Do While currentID = savedID and not rs.eof if Rs(""LinkName"") <> """" Then %> insDoc(aux1, gLnk(0, ""<%= Rs(""LinkName"") %>"", ""<%= Rs(""LinkURL"") %>"")) <% end if Rs.MoveNext if not rs.eof then currentID = Rs(""ID"") Loop End If if currentID = """" then rs.movenext Loop %> </script> <script> initializeDocument() </script> <base target=""basefrm""> <title></title> </head> <body bgcolor=""white""> </body> </html>
