treeview十八般武艺,js选择和绑定权限树

最佳JS实现treeview权限树遍历方法（当然，要以客户需求为主）：

 1     function getParentByTagName(element,tagName)
 2     {
 3         var    parent = element.parentNode;
 4         var    upperTagName = tagName.toUpperCase();
 5         while (parent && (parent.tagName.toUpperCase() != upperTagName))
 6         {
 7             parent = parent.parentNode ? parent.parentNode : parent.parentElement;
 8         }
 9         return parent;
10     }
11 
12     function setParentChecked(objNode)
13     {
14         var    objParentDiv = getParentByTagName(objNode,"div");
15         if(objParentDiv == null || objParentDiv == "undefined")
16             return;
17         var    objID =    objParentDiv.getAttribute("ID");
18         var    objParentCheckBox =    document.getElementById(objID.replace("Nodes","CheckBox"));
19         if(objParentCheckBox == null || objParentCheckBox    == "undefined")
20             return;
21         if(objParentCheckBox.tagName!="INPUT" && objParentCheckBox.type    == "checkbox")
22             return;
23        
24         //objParentCheckBox.checked = true;
25         if(objParentCheckBox.value == "117") 
26         {
27             //alert("ok");
28             objParentCheckBox.checked=false;
29         }
30         else
31         {
32             if (objNode.checked=true) objParentCheckBox.checked=true;
33         }
34         
35         setParentChecked(objParentCheckBox);
36     }
37     function setParentUnChecked(objNode)
38     {
39         var    objParentDiv = getParentByTagName(objNode,"div");
40         if(objParentDiv == null || objParentDiv == "undefined")
41             return;
42         var    objID =    objParentDiv.getAttribute("ID");
43         var    objParentCheckBox =    document.getElementById(objID.replace("Nodes","CheckBox"));
44         if(objParentCheckBox == null || objParentCheckBox    == "undefined")
45             return;
46         if(objParentCheckBox.tagName!="INPUT" && objParentCheckBox.type    == "checkbox")
47             return;
48         if (objNode.checked=false) objParentCheckBox.checked=false;
49         objParentCheckBox.checked = false;
50         setParentUnChecked(objParentCheckBox);
51     }
52 
53     function setChildCheckedState(div,state)
54     {
55         var    objchild = div.childNodes;
56         var    count =    objchild.length;
57         for(var    i=0;i<objchild.length;i++)
58         {
59             var    tempObj    = objchild[i];
60             if(tempObj.tagName=="INPUT"    && tempObj.type    == "checkbox")
61             {
62                 tempObj.checked    = state;
63             }
64 //                 debugger;
65             setChildCheckedState(tempObj,state);
66         }
67     }
68     function TreeNodeChecked()
69     {
70         var    objNode    = window.event.srcElement;
71         if(objNode.tagName!="INPUT"    || objNode.type!="checkbox")
72             return;
73 //             debugger;
74         if(objNode.checked == true)
75         {
76             setParentChecked(objNode);
77         }
78         else
79         {
80             //setParentUnChecked(objNode);
81             
82         }
83         var    objID =    objNode.getAttribute("ID");
84         var    objParentDiv = document.getElementById(objID.replace("CheckBox","Nodes"));
85         if(objParentDiv==null || typeof(objParentDiv) == "undefined")
86             return;
87         setChildCheckedState(objParentDiv,objNode.checked);
88 
89     }
90 
91 </script>

后台递归遍历绑定treeview被选节点:

 1     /// <summary>
 2     /// 判断TreeView被选节点
 3     /// </summary>
 4     /// <param name="tv">TreeView名称</param>
 5     private void InitTreeChecked(TreeNode parentID, string menuID)
 6     {
 7 
 8         if (parentID.Value == menuID)//根节点
 9         {
10             parentID.Checked = true;
11             //parentID = tvMenu.Nodes[0];
12         }
13         else
14         {
15             if (parentID.ChildNodes.Count != 0)
16             {
17                 //for (int i = 0; i < parentID.ChildNodes.Count; i++)//一级子节点
18                 foreach(TreeNode childID in parentID.ChildNodes)
19                 {                 
20                         //if (parentID.ChildNodes[i].Value.Trim().ToString() == menuID.Trim())
21                         if(childID.Value.Trim().ToString() == menuID.Trim().ToString())
22                         {
23                             childID.Checked = true;
24                             return;
25                         }
26                         else
27                         {
28                             //if (parentID.ChildNodes[parentID.ChildNodes.Count-1].Value.Trim().ToString())
29 
30                             parentID = childID;
31                             this.InitTreeChecked(parentID, menuID);                            
32                         }                        
33                  }                 
34             }        
35             else{} 
36         }
37     }

07年实现新添treeview权限的JS源码：

07年JS实现更新treeview权限树(建议后台遍历treenodes)：

           if (objNode.tagName=="INPUT"    && objNode.type=="checkbox")   
           {   
               objNode.checked=false;   
            }   
  
        }   
           
       for (i=0;i<document.form1.length ;i++)   
        {

           if (objNode.tagName=="INPUT"    && objNode.type=="checkbox")   
           {

同样效果后台遍历代码如下：

 1     /// <summary>
 2     /// 读取treeview上所有节点值
 3     /// </summary>
