这是暑假的课设，也是我学习JS的动力，提前使用C++实现一遍过了，然而实现过后打算再用JS写一遍时，有一种无从下手的感觉，所以参考了一下其他人的代码，也由此认识到了jQuery框架中对于动画实现部分的便利，于是又开始花时间学习jQuery框架，这个就是纯看菜鸟教程学习的了，学习得倒也很快，所以再次下手做2048时动画效果实现部分就是采用了jQuery中的相关部分。

一、游戏流程介绍
二、具体代码展示
三、C++版本代码展示
四、后记
一、游戏流程介绍
流程图展示
game：游戏状态 updateGameView()：更新游戏界面 createNumber()：产生新的数字格 check()：判断游戏状态 check2048()：判断是否出现2048 allCheck()：判断是否游戏失败而结束，即无空白格，也无相邻可合并数字格
二、具体代码展示
