TreeView 客户端事件

服务器端代码：
        Microsoft.Web.UI.WebControls.TreeNode tn = new Microsoft.Web.UI.WebControls.TreeNode();
     tn.Text = tmp.Name;
     tn.NodeData = tmp.StaffID +"-"+tmp.Name;
     tn.ImageUrl ="css\\images\\icon_pp.gif";
     //tn.SelectedImageUrl ="images\ajz_close.gif";
     tn.ID =tmp.BranchID+"\" onclick=\"GetAttribute()";
客户端：
function GetAttribute() {
   //http://ayu812.cnblogs.com/archive/2005/11/21/281020.aspx
       //  alert(TreeView1.getTreeNode(TreeView1.selectedNodeIndex).getAttribute("Text"));NodeData
      //  alert('txtttttttt');
         var txt=TreeView1.getTreeNode(TreeView1.clickedNodeIndex).getAttribute("Text");
         var value =TreeView1.getTreeNode(TreeView1.clickedNodeIndex).getAttribute("NodeData");
}
