利用原生JS實現(xiàn)歡樂水果機小游戲
更新時間：2022年10月14日 17:22:41 作者：RollinsLy
這篇文章主要介紹了利用原生JS實現(xiàn)歡樂水果機小游戲,本文通過實例代碼給大家介紹的非常詳細，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值，需要的朋友可以參考下
簡介：
玩家點擊某個押注物品則在該物品上下。點擊開始則游戲開始，如果沒有下則不能開始游戲。
游戲中的物品有八中，分別為：蘋果、西瓜、檸檬、橙子、鈴鐺、77、雙星、BAR。
在放行游戲區(qū)左右方為押注區(qū)，每種物品下方有加減號按鈕，每次點
擊加號增加一個注金，反之減號就減少一個注金
開始： 開始鍵
獎勵：GOOD LUCK
由于這個時低配版的，我就沒有按照原版的寫進去，就是中了GOOD LUCK直接獲得15分。
出于好耍，本人想起了小時候玩過的水果機，js也學(xué)了一會兒了，就想用它寫一個簡單的水果機玩玩，廢話不多說，直接上代碼，只有js有注釋，html和css就沒有注釋了。
這是樣式圖
這里是html代碼：
<!DOCTYPE html>
<html lang="en">

<link rel="stylesheet" href="Fruit.css" rel="external nofollow" >
