Answer 3

<搜集江雨大哥的例子>每次只有一个节点被选用 <script language="javascript">                                       function TreeView1.onexpand()                     {                            var clickedNodeIndex=TreeView1.clickedNodeIndex;                                                 var nodeArray=new Array();                                                        var i=clickedNodeIndex.lastIndexOf(".");                                                        var pIndex;                                                        if(i==-1)                            {                                   //Root Node                                   nodeArray=TreeView1.getChildren();                            }                            else                            {                                   pIndex=clickedNodeIndex.substring(0,i);                                   var pNode=TreeView1.getTreeNode(pIndex);                                   nodeArray=pNode.getChildren();                            }                                                        for(i=0;i<nodeArray.length;i++)                            {                                   var index;                                   if(pIndex==null)                                   {                                          index = i + "";                                   }                                   else                                   {                                          index = pIndex + "." + i;                                   }                                                                      var cNode;                                   cNode=nodeArray[i];                                   if(index!=clickedNodeIndex)                                   {                                          cNode.setAttribute("Expanded",false);                                   }                            }                     }              </script>

自己响应事件处理（select after事件或者mouse事件），我是这么做的。
