关于生成目录树结构的类
本程序有两文件test.asp 和tree.asp 还有一些图标文件
1。test.asp 调用类生成树 代码如下
<%@ Language=VBScript %> <html> <head> <link rel="stylesheet" href="tree.css"> <title>tree</title> </head> <!-- #include file="tree.asp" --> <% '======================================== ' BUILDING A TREE PROGRAMATICALLY '======================================== ' This approach would be best suited for building ' dynamic trees using For..Next loops and such. Set MyTree2 = New Tree MyTree2.Top = 10 MyTree2.Left = 10 MyTree2.ExpandImage = "plus.gif" MyTree2.CollapseImage = "minus.gif" MyTree2.LeafImage = "webpage.gif" ' Notice the indentation used to reprensent the hierarchy Set Node1 = MyTree2.CreateChild("script") Set SubNode1 = Node1.CreateChild("server") Set secSubNode1 = SubNode1.CreateChild("html") secSubNode1.CreateChild "<A HREF=""http://127.0.0.1/"">asp</A>" secSubNode1.CreateChild "<A HREF=""http://127.0.0.1/"">php</A>" secSubNode1.CreateChild "<A HREF=""http://127.0.0.1/"">jsp</A>" Set SubNode2 = Node1.CreateChild("os") SubNode2.CreateChild "<A HREF=""#"">winnt</A>" SubNode2.CreateChild "<A HREF=""#"">win2000</A>" Set Node2 = MyTree2.CreateChild("Desktop") Node2.CreateChild "<A HREF=""#"">Area Code Lookup</A>" Node2.CreateChild "<A HREF=""#"">Arin Based Whois Search</A>" Node2.CreateChild "<A HREF=""#"">World Time Zone Map</A>" MyTree2.Draw() Set MyTree2 = Nothing %> </BODY> </HTML>
2。tree.asp 类的定义 代码如下
<% '****************************************************** ' Author: Jacob Gilley ' Email: avis7@airmail.net ' My Terms: You can use this control in anyway you see fit ' cause I have no means to enforce any guidelines ' or BS that most developers think they can get ' you to agree to by spouting out words like ' "intellectual property" and "The Code Gods". ' - Viva la Microsoft! '****************************************************** Dim gblTreeNodeCount:gblTreeNodeCount = 1 Class TreeNode Public Value Public ExpandImage Public CollapseImage Public LeafImage Public Expanded Private mszName Private mcolChildren Private mbChildrenInitialized Public Property Get ChildCount() ChildCount = mcolChildren.Count End Property Private Sub Class_Initialize() mszName = "node" & CStr(gblTreeNodeCount) gblTreeNodeCount = gblTreeNodeCount + 1 mbChildrenInitialized = False Expanded = False End Sub Private Sub Class_Terminate() If mbChildrenInitialized And IsObject(mcolChildren) Then mcolChildren.RemoveAll() Set mcolChildren = Nothing End If End Sub Private Sub InitChildList() Set mcolChildren = Server.CreateObject("Scripting.Dictionary") mbChildrenInitialized = True End Sub Private Sub LoadState() If Request(mszName) = "1" Or Request("togglenode") = mszName Then Expanded = True End If End Sub Public Function CreateChild(szValue) If Not mbChildrenInitialized Then InitChildList() Set CreateChild = New TreeNode CreateChild.Value = szValue CreateChild.ExpandImage = ExpandImage CreateChild.CollapseImage = CollapseImage CreateChild.LeafImage = LeafImage mcolChildren.Add mcolChildren.Count + 1, CreateChild End Function Public Sub Draw() LoadState() Response.Write "<table border=""0"">" & vbCrLf Response.Write "<tr><td>" & vbCrLf If Expanded Then Response.Write "<a href=""javascript:collapseNode('" & mszName & "')""><img src="/UploadFiles/2021-04-02/">以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
