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：

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

如何利用原生JS实现触摸滑动监听事件
前言 今天写一个小Demo,有个地方涉及到了左滑右滑的逻辑,本来想着用插件来着,但是想到自己好久没用原生JS写滑动的监听了,所以试着用原生JS来实现了一下,毕竟温故而知新嘛,同时做个记录.先把实现的效果贴出来: 构思 想要写出丝滑的触摸滑动事件的监听,要考虑以下3个方面的逻辑: 距离: 滑动距离要大于40 时间: 滑动时间小于在0.5秒,即500毫秒内完成手指按下,拖动,离开(避免只是手指在屏幕就触发) 滑动方向: 左右滑动的条件是:X轴移动的距离大于Y轴移动的距离,为正则向左,为负则向右 上下
