treeview節點控制

點開treeview的一個節點,其他節點都收縮

 

    <script language="javascript">
        function initTree()
          { 
          var tree = document.all["tr1"];
          tree.attachEvent("onexpand", SelectedIndexChange); //追加個事件
       }
       function SelectedIndexChange()
       {
       var temp = this.tr1.clickedNodeIndex;
       var nodes = new Array();
       nodes = this.tr1.getChildren();
       for(i=0;i<nodes.length;i++)
       {
       if(i!=temp)
       {
       if(i<9)
        nodeIndex = "0"+i;
        this.tr1.getTreeNode(nodeIndex).setAttribute('expanded','false');
        }
        }
        }
