JavaScript基于面向对象实现的猜拳游戏

时间：2021-05-26

本文实例讲述了JavaScript基于面向对象实现的猜拳游戏。分享给大家供大家参考，具体如下：

html代码：

<!doctype html><html> <head> <meta charset="UTF-8"> <title>猜拳游戏</title> <link rel="stylesheet" href="css/game.css" rel="external nofollow" ></link> </head> <body> <div id="game"> <ul class="panel"> <li> <p class="name">我：name</p> <div class="anim user"></div> </li> <li> <p class="name">电脑：name</p> <div class="anim comp"></div> </li> </ul> <div class="op"> <button id="play" onclick = "game.Caiquan();">开始</button> </div> <div id="text" class="text">请开始游戏...</div> <ul id="guess" class="guess"> <li> <div class="guess0" onclick="game.verdict(0)">石头</div> </li> <li> <div class="guess1" onclick="game.verdict(1)">剪刀</div> </li> <li> <div class="guess2" onclick="game.verdict(2)">布</div> </li> </ul> </div> <script type="text/javascript" src="js/game.js"></script> </body></html>

css样式(字体：迷你简卡通)

*{ margin:0px; padding:0px; font-family:'迷你简卡通'; font-size:28px;}html,body{ width:100%; height:100%; background:rgba(244, 184, 202, 1);}ul{ list-style:none;}#game{ width:800px; height:600px; margin:auto; top:20%;}#game ul{ width:100%; height:415px;}#game ul li{ width:50%; height:100%; float:left; text-align:center;}#game ul li .anim{ width:223px; height:337px; border:10px solid #ff6699; border-radius:50%; margin:20px auto 0; background-position:center; background-repeat:no-repeat;}.user{ background:url('../img/readyl.png');}.comp{ background:url('../img/readyr.png');}#game .op{ width:100%; text-align:center;}#game .op button{ width:200px; height:60px; border:10px solid #ff6699; background:rgb(253, 217, 227); border-radius:50%; outline:none; cursor:pointer; font-weight:bold;}#game .op button:hover{ border-color:#ff0000; background-color:#ff0000; font-size:36px; color:rgb(253, 217, 227);}#game .op button.disabled{ border-color:#bbb; color:#bbb; background-color:#ccc; font-size:28px; cursor:default;}#game .guess{ width:220px; height:100%; position:fixed; top:0px; left:0px; display:none;}#game ul.guess li{ width:100%; height:32%;}#game ul.guess li div{ width:100%; height:90%; border:10px solid #ff6699; border-radius:50%; background-position:center; background-repeat:no-repeat; cursor:pointer; background-color:rgba(244, 184, 202, 1);}#game ul.guess li div:hover{ background-color:#ff6699; color:#fff;}div.guess0{ background-image:url('../img/0.png');}div.guess1{ background-image:url('../img/1.png');}div.guess2{ background-image:url('../img/2.png');}#game div.text{ margin-top:20px; text-align:center; font-size:50px; font-weight:bold;}
