var tree = Ext.create('Ext.tree.Panel', {
		title : 'Simple Tree',
		width : 200,
		height : 250,
		queryMode : 'local',
		id : 'treePanel-id',
		store : store,
		rootVisible : false,
		listeners : {
			'itemclick' : function(view, record, items, index, e) {
				alert(items);
				if (record.get('leaf') == false) {
					return;
				} else {
					Ext.MessageBox.show({
								title : '节点操作',
								msg : 'itemclick：index=' + index + ",text="
										+ record.data.text,
								icon : Ext.MessageBox.INFO
							});
				}
			},
			'itemcontextmenu' : function(menutree, record, items, index, e) {
				e.preventDefault();
				e.stopEvent();
				var obj = record;

				while (!obj.parentNode.isRoot()) {
					obj = obj.parentNode;
				}
				var rootId = obj.getId();
				if (rootId != 180 && rootId != 190) {
					return;
				} else {
					var nodemenu = new Ext.menu.Menu({
						floating : true,
						items : [{
							text : "添加文件夹",
							// icon:'images/add.gif',
							// iconCls:'leaf',
							handler : function() {
								if (record.get('leaf') == false) {
									Ext.MessageBox.prompt("标题", "請輸入",
											function(btn, text) {
												if (btn == "ok") {
													record.appendChild({
																text : text,
																id : new Date()
																		.getTime(),
																expanded : true
															});
												}
											}, this, false, // 表示文本框为多行文本框
											"新添加文件夹");
								}

							},
							listeners : {
