'''I m posting my treeview code here to understand properly...
 
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
       'On the first page visit, populate the photo tree and select the root node
       If Not Page.IsPostBack Then
           PopulateTree()

           PictureTree.Nodes(0).Select()


       End If
   End Sub

   Private Const VirtualImageRoot = "~/"
   Private Sub PopulateTree()
       'Populate the tree based on the subfolders of the specified VirtualImageRoot
       Dim rootFolder As New DirectoryInfo(Server.MapPath(VirtualImageRoot))
       Dim root As TreeNode = AddNodeAndDescendents(rootFolder, Nothing)

       'Add the root to the TreeView
       PictureTree.Nodes.Add(root)
   End Sub

   Private Function AddNodeAndDescendents(ByVal folder As DirectoryInfo, ByVal parentNode As TreeNode) As TreeNode
       'Add the TreeNode, displaying the folder's name and storing the full path to the folder as the value...
       Dim virtualFolderPath As String
       If parentNode Is Nothing Then
           virtualFolderPath = VirtualImageRoot
       Else
           virtualFolderPath = parentNode.Value & folder.Name & "/"
       End If

       Dim node As New TreeNode(folder.Name, virtualFolderPath)

       'Recurse through this folder's subfolders
       Dim subFolders As DirectoryInfo() = folder.GetDirectories()
       For Each subFolder As DirectoryInfo In subFolders
           Dim child As TreeNode = AddNodeAndDescendents(subFolder, node)
           node.ChildNodes.Add(child)
       Next

       Return node     'Return the new TreeNode   End Function

推荐答案

下面的Java脚本代码可以获取所选节点的内容.

Below java script code can fetch the content of the selected node.

<script language="javascript" type="text/javascript">
       function showTreeNodeContent() {
           var tree = document.getElementById('<%=TreeView1.ClientID %>');
           var nodes = tree.getElementsByTagName('a');
           for (var n = 0; n < nodes.length; n++) {
               var getContent = nodes[n].getAttribute('myattr');
               }
           }
       }
   </script>
