利用Easy UI生成非同步樹以及動態新增標籤頁

<ul id="menuTree" class="easyui-tree">

$('#kunlunMenuTree').tree('options').url = "${ctp}/menu/menuInfo?id="+node.id;

$('#menuTree').tree({
			url: '${ctp}/menu/menuInfo',  //向後臺傳送id,獲取根節點  
            lines:true,  
            
            //節點點開前觸發
            onBeforeExpand:function(node){  
                $('#menuTree').tree('options').url = "${ctp}/menu/menuInfo?pid="+node.pid+"&flag="+node.flag;  
            },
            
            //返回過濾過的資料進行展示，這裡返回的資料作為點開節點的子節點
            loadFilter: function(data){      
				if (data.msg){      
				     return data.msg;      
				} else {      
				    return data;      
				}      
			},  
					
			onClick: function(node){
				//如果節點有url屬性，則開啟一個標籤頁
				if(node.url!=null){
					addTab(node.text, node.url,node.id);
				}
			}
		});
