In JavaScript and jquery, there is a way of handling events, and when we write a program to implement certain functions, we find that using native DOM events and events encapsulated in jquery can achieve the same effect, then perhaps we will think that the difference between them is not very large, Even basically there is no difference. This view is wrong, in fac

This article introduces the use of traditional events to simulate modern events, very simple and practical, the need for small partners can refer to.
As we all know, the modern event binding (attachevent) in IE has many problems compared with the standard of the AddEventListener.
For example: memory leaks, recurring events and triggers are flashback execution,
This blog is a presentation that describes using COOCS2DX Lua with touch events. For Main.lua files, look in the previous articles in the same series.
The underlying content will no longer be explained, and this article will focus on the content. Use the steps to create the listener you want (touch listener, Keyboard listener). Listener settings are swallowed. The listener sets the type of event to listen on (CC. Handler.event_touch_began), as well as
after the handle attribute is read. Therefore, handleallocated is used to check the existence of the handle, instead of creating it.

What exactly is an event?
Part 1th: The weak event of the listener (listener-side)
Online about this aspect of the code is more and more chaotic, here to tidy up and improve. Add Eventvar addevent = function (obj, type, fn) { if (obj.addeventlistener) obj.addeventlistener (type, FN, false); else if (obj.attachevent) { obj["e" +type+fn] = fn; Obj.attachevent ("On" +type, function () { obj["E" +type+fn].call (obj, window.event); });} ;removing eventsvar removeevent = function (obj, type, fn) { if (obj.removeeventlistener) obj.removeeventlist

As we all know, the modern event binding (attachevent) in IE has many problems compared with the standard of the AddEventListener.
For example: memory leaks, recurring events and triggers are flashback execution, and so on.
The following is a traditional event method to handle the binding of an encapsulated event:
Addevent.id = 1;
Event counter function addevent (obj, type, fn) {if (Obj.addeventlistener) {Obj.addeventlistener (type, FN, fal
