TreeView中checkbox的取值问题

Question

//后台绑定数据代码
        TreeOrg.Nodes.Clear();
        _OrgTable = new OrgainzationManager()._SearchOrgTree(MyStateManager.DomainID, MyStateManager.OrgID, "and valid=1");

            node.Checked = row["OffDay_OrgId"].ToString() != "";
            TreeOrg.Attributes.Add("onClick", "client_OnTreeNodeChecked()");
            AddSubNode(node, _OrgTable, node.Checked.ToString());//添加子节点
            TreeOrg.Nodes.Add(node);点击复选框事件

 }

Answer 1

用颜色标出来了居然没变色inputObjs[i].title 取到的始终为空值   这是为啥

Answer 2

<asp:TreeView ID="TreeView1" runat="server" onclick="javascript:client_OnTreeNodeChecked();" NodeIndent="10" ShowCheckBoxes="All" ShowLines="True">  
function checkParent (obj)  
  {  
  while(obj != null)  
  {  
  var tagName = obj.tagName.toLowerCase();

  }  
    
  if(tagName == "table")  
  {  
  var checkBox = obj.getElementsByTagName("INPUT");  
  if(checkBox.length >0)  
  {  
  checkBox[0].checked = true;  
  }  
  obj = obj.parentElement.previousSibling;  
  }  
  else  
  obj = obj.parentElement;  
  }  
  }  
    
  function client_OnTreeNodeChecked()

  }  
或
foreach(TreeNode no  in this.tvMenu.Nodes) 
            { 
                GetTree(no); 
                GetChildTree(no); 
            } 
private void GetTree(TreeNode node) 
        { 
            if (node.Checked == true) 
            { 
              int i=int.Parse(node.Value.ToString().Trim());                
            }         } 
rivate void GetChildTree(TreeNode node) 
        { 
            foreach (TreeNode nd in node.ChildNodes) 
            { 
                if (nd.Checked) 
                { 
                
                } 
                if(nd.ChildNodes.Count >0) 
                    GetChildTree(nd); 
            } 
        }

Answer 3

cs:TreeOrg
js: var inputObjs = document.getElementById("OrgTree").getElementsByTagName("input");
   又是OrgTree...是不是id写错了？
