??????? tree如果节点比较多的时候查找一个节点很费事,因此需要在树的上面添加一个模糊搜索框,当文本的内容发生变化的时候,自动搜索树并打开选中相应的节点。
?
?????? 代码如下:
?
??????
//starts at the given node, walks up the tree opening nodes as it goes private function expandParents(xmlNode:XML):void { while (xmlNode.parent() != null) { xmlNode = xmlNode.parent(); myTree.expandItem(xmlNode,true, false); } }//expandParents //uses e4x to find a node, then calls expand parents to make it visible, //then selects it private function findNodeById(sId:String):void { var xmllistDescendants:XMLList = _xmlData.descendants().(@eid == sId); //如果是模糊搜索可以用下面的代码 //var xmllistDescendants:XMLList = treeXml.descendants().(@name.toString().indexOf(nameStr)>-1); expandParents(xmllistDescendants[0]); myTree.selectedItem = xmllistDescendants[0]; }//findNodeById
