过完年来公司，没什么事，主管说研究下html5 游戏，然后主管就给了一个斗地主的demo，随后我就开始看代码，
现在我看了html5以及canvas相关知识和斗地主的demo后，自己用demo上的素材试着写了个斗地主，代码没重构好，欢迎赐教。
话不多说，下面就一步一步解释下吧
只有一个common.js文件
1、资源类

62 { path: ‘img/54.jpg‘, data: null, type: 15, visible: false, se: 2 }
63 ]
64 });
Resource.Images是素材数组(几个按钮，文本，54张牌,背景图片等),大家可以下载demo看看 2、Lables类,在Canvas画布上画文本的,比如按钮文字,相关知识请看canvas教程
1 var Labels = Class.create();
2 $.extend(Labels.prototype, {
3 initialize: function (cxt) {
4 this.cxt = cxt;
5 },
6 setText: function (text, postion) {
7 this.cxt.font = ‘bold 20px serif‘;
8 this.cxt.fillStyle = ‘#000000‘;
9 this.cxt.textAlign = ‘center‘;
10 this.cxt.fillText(text, postion.x, postion.y);
11 }
12 });
这个类的方法setText主要是根据设置的字体，字体大小，字体颜色，在Canvas上画文本的，this.cxt这个是canvas上下文(每个教程的叫法不一样)，首先this.cxt.font = ‘bold 20px serif‘;这个是设置字体大小，样式等，this.cxt.fillStyle = ‘#000000‘;这个
是设置字体颜色，this.cxt.textAlign = ‘center‘;这个是设置字体对齐方式,this.cxt.fillText(text, postion.x, postion.y);这个是开始在canvas上画文本,postion.x, postion.y分别是x坐标和y坐标。
3、DdZGame游戏类，主要功能就是初始化斗地主，发牌，抢地主等，出牌未完待续，后续更新
1 var DdZGame = Class.create();
2 DdZGame.Statics = { DealedNums: 0, isLeftFirstDeal: true };
3 $.extend(DdZGame.prototype, {
4 initialize: function () {
5 DdZGame.Statics.IsGetLander = false;

37

initialize：这个函数是构造函数，初始化一些起始变量。
initEvt这个里是初始化canvas事件,canvas点击事件不像svg那样，因为canvas是一帧一帧画上去的，html dom里是看不到里面的每个元素，javascript自然也无法获取到canvas里的某个元素,那canvas元素点击事件是怎么处理的了？
首先定义下canvas这个画布的事件，然后定义获取鼠标的坐标，再算出在canvas相对坐标，因为每个元素也都有自己的坐标和宽高，所以可以根据这个坐标判断这个坐标是否在某个元素内。
onControlClick：这个函数是根据上面算出的坐标，判断此坐标在哪个元素内，如果在元素内，并且定义了onclick函数(注:此处并不是真正的元素事件，只是对象的一个函数属性)，然后调用onclick函数，执行相应的代码。
loadImages：这个是加载所有图片，图片加载完成之后，就开始在canvas上画初始的元素。
init：这个函数就是调用loadImages函数，然后所有图片加载完毕之后，调用回调函数，在canvas上画初始的元素
Dealing ：这个是发牌，每方的牌都是随机的，if(DdZGame.Statics.DealedNums >= 51)发了51张牌之后，就剩3张底牌，然后再把这51张牌和3张底牌画在canvas上
GetLander ：这个是抢地主，谁先抢地主是随机的，如果是先随机到电脑抢地主，那抢地主的分数也是随机的。
