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。

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
