Ext事件，哈哈哈没有flex的事件爽

Ext事件，哈哈没有flex的事件爽

 var myEventer;								//事件对象;
	var MyEventer = function(){
		this.addEvents({						//声明一系列事件，形成一个事件链;
	       "createLineFinished": true,			//动态创建一行完成;(先触发1)
	       "createLineFinishedAfter": true,		//动态创建一行完成之后;(后触发2)
	       "loadFeatureDataFinish": true,		//加载数据完成;(后触发3)
	       "loadedAllDataFinish": true			//所有数据加载完成;	
	   });
	}
	Ext.extend(MyEventer, Ext.util.Observable);	

		myEventer = new MyEventer();
		myEventer.on("createLineFinished", function(){
			createTabFinished++;
			myEventer.fireEvent("createLineFinishedAfter", createTabFinished);
		});
		myEventer.on("loadedAllDataFinish", function(){
			//本页已经初始化完成;
			if(loadPanelMask)loadPanelMask.hide();			//去掉遮罩loadPanelMask在add_tagruler.html声明;
		});
