作者：风顶
这篇文章主要为大家详细介绍了JavaScript实现简单打地鼠游戏，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
本文实例为大家分享了JavaScript实现打地鼠游戏的具体代码，供大家参考，具体内容如下
效果如下：
html代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
<script src="js/index.js"></script>
<link rel="stylesheet" type="text/css" href="css/index.css" />
<style type="text/css">
</style>
</head>
<body>
<div id="controlCenter">
<div class="buttons">
<button class="buttonCss" onclick="startGame()">开始</button>
<button class="buttonCss" onclick="pauseGame()">暂停</button>
<button class="buttonCss" onclick="stopGame()">停止</button>
</div>
<div class="buttons">
<div class="score"><span>得分:</span><span class="spanCss" id="scoreId">0</span></div>
<div class="score">时间:<span class="spanCss" id="timeId">00:00</span></div>
</div>
</div>
<div id="mainFrame" class="mouseMiddle">
