利用原生JS实现欢乐水果机小游戏
简介：
玩家点击某个押注物品则在该物品上下注。点击开始则游戏开始，如果没有下注则不能开始游戏。游戏中的物品有八中，分别为：苹果、西瓜、柠檬、橙子、铃铛、77、双星、BAR。在放行游戏区左右方为押注区，每种物品下方有加减号按钮，每次点击加号增加一个筹码注金，反之减号就减少一个筹码注金开始： 开始键奖励：GOOD LUCK由于这个时低配版的，我就没有按照原版的写进去，就是中了GOOD LUCK直接获得15分。出于好耍，本人想起了小时候玩过的水果机，js也学了一会儿了，就想用它写一个简单的水果机玩玩，废话不多说，直接上代码，只有js有注释，html和css就没有注释了。这是样式图
这里是html代码：

加上一点简单的css布局
