使用方法

首先，加载 poker.js

<script src="poker.min.js"></script>

接下去你可以从3种方法里选择一种来创建牌

方法1，创建DOM元素

调用Poker.getCardImage或Poker.getCardCanvas来获取<img>或<canvas>元素

//在body末尾插入一个<img>
document.body.appendChild(Poker.getCardImage(60,'hearts','q'));
//在body末尾插入一个<canvas>
document.body.appendChild(Poker.getCardCanvas(60,'hearts','q'));

方法2，获取base64的png图像数据

调用Poker.getCardData来获取数据

//获取图像数据并且存储在变量pokerHQ里
var pokerHQ = Poker.getCardData(60,'hearts','q');

方法3，在你自己的canvas里画牌

在DOM里添加你自己的canvas容器

<canvas id="myowncanvas" width="1280" height="720"></canvas>

取得canvas的2d对象，在里面画牌

var canvas = document.getElementById('myowncanvas').getContext('2d');
canvas.drawPokerCard(10, 10, 120, 'hearts', '6');
