1，html写好界面，定义好class和id2，为了模拟出扑克牌21点游戏，应先定义卡牌池中有1-10，J,Q,K每个数字和字母分别有4个
3，js中实现界面交互，如点击开始按钮，随机从卡牌池中抽取一个数字或字母存入临时变量a，并附于点数之和num其相应的点数
4，点击抽牌按钮随机从卡牌池剩余的卡牌中抽取，对应的卡牌存入变量a中，点数之和num=num+本次抽卡的点数
5，当num>21时提示玩家爆点，小于21点时可选按钮抽牌，等于21点时提示恭喜之类的话，如果点击完成抽牌则记录此玩家点数
6，同理可扩充玩家至2,3,4....个，原理相同，不同玩家存储对应的变量就可以了，最终通过所有<=21点的玩家num,num1,num2来判断输赢
7，同理可设置庄家，庄家在与其他玩家点数相同时赢得对方
8，在此基础上就能增添许多功能了，比如每个玩家默认100金币，有底注，每轮开始的时候可加注，如玩家不跟则底注输掉无法参加游戏，等等之类的各种规则随便发挥
