带CheckBox的TreeView网上出错问题解决办法

问题描述：
TreeView上传到服务器，预览效果发现节点图片不显示、展开合并功能缺失.
解决办法：
　　以下是我个人的解决办法，最终的效果实现了，但是还有一点点小遗憾，就是页面上有基于微软的调用js的报错信息。
CheckBox选择JS，代码是网上找的。

 1 <script language="javascript" type="text/javascript">

 2     var Obj_;

 3     document.onclick=function()

 4     {

 5         if(event.srcElement.tagName=="INPUT")

 6         {

 7             Obj_=event.srcElement;

 8             getNextElement(event.srcElement);

 9         }

10     }

11     function getNextElement(srcObj)

12     {

13         var i=0;

14         while(srcObj.tagName!="TABLE")

15         {

16             srcObj=srcObj.parentNode;

17             i++;

18             if(i>20) break;

19         }

20         //

21       

22         if(srcObj.nextSibling==null)

23         {

24             selectParentNode(srcObj);

25             return;

26         }

27         if(srcObj.nextSibling.tagName=="DIV")

28         {

29             var targetObj=srcObj.nextSibling;

30             selectThem(targetObj);

31         }

32 //        else if(srcObj.nextSibling.tagName=="TABLE")

33 //        {

34 //            //

35 //        }

36         selectParentNode(srcObj);

37     }

38     function selectThem(targetObj_)

39     {

40         var ChexBox_Obj=targetObj_.getElementsByTagName_r("INPUT");

41         for(var i=0;i<ChexBox_Obj.length;i++)

42         {

43             ChexBox_Obj[i].checked=Obj_.checked;

44         }

45     }

46     function selectParentNode(obj)

47     {

48         while(obj.parentNode.previousSibling.tagName=="TABLE")

49         {

50             //

51             var parentObj=obj.parentNode;

52             var ChexBox_brother=parentObj.getElementsByTagName_r("INPUT");

53             var counter_=0;

54             for(var i=0;i<ChexBox_brother.length;i++)

55             {

56                 if(ChexBox_brother[i].checked) counter_++;

57             }

58             //

59             var parentNContiner=obj.parentNode.previousSibling;

60             var CheckB=parentNContiner.getElementsByTagName_r("INPUT");

61             CheckB[0].checked=counter_>0?true:false;

62             obj=parentNContiner;

63         }

64     } 

65 </script>

展开、合并JS，网上代码修改

 1 <script language="javascript" type="text/javascript">

 2 function TreeView_ToggleNode(data, index, node, lineType, children) {

 3 var img = node.childNodes[0];

 4 var newExpandState;

 5 try {

 6 if (children.style.display == "none") {

 7 children.style.display = "block";

 8 newExpandState = "e";

 9 img.src = "../../images/parts/tree_folder3.gif";

10 }

11 else {

12 children.style.display = "none";

13 newExpandState = "c";

14 img.src = "../../images/parts/tree_folder4.gif";

15 }

16 }

17 catch(e) {}

18 }

19 </script>

页面代码：

1 <asp:TreeView ID="TreeView_1" ShowCheckBoxes="all" runat="server" ShowExpandCollapse="true" CollapseImageUrl="~/images/parts/tree_folder3.gif" ExpandImageUrl="~/images/parts/tree_folder4.gif" NoExpandImageUrl="~/images/parts/tree_folder3.gif"></asp:TreeView>
