  相信大家都玩过飞翔的小鸟吧,当然,可能已经有很多人因为这个游戏砸了不少手机。吼吼。

 

  废话不多说,回到主题,源码如下。

 

  博客园上传空间大小有限制,没法上传了,需要打包源码的朋友们请留言邮箱地址。当然还有,不要忘了点赞哦~谢谢大家的支持。

 

 

  直接上源码:一共是三个文件:页面、js、css。

 

HTML(index.html)页面源码如下:

 1 <!DOCTYPE html>
 2 <html>
 3 <head>
 4   <meta charset="UTF-8">
 5   <title>飞翔的字母 - 孤影</title>
 6     <link rel="stylesheet" href="style.css" media="screen" type="text/css" />
 7 </head>
 8 
 9 <body>
10   <div id="canvasContainer"></div>
11     <span id="textInputSpan">
12       1.输入内容,2.点击屏幕开始游戏,请输入内容(最大8个字符):
13       <input id="textInput" maxlength="10" type="text" width="150" />
14       <button onclick="changeText()">确定!</button>
15     </span>    
16   <script src="index.js"></script>
17 </body>
18 </html>

 

JavaScript脚本文件(index.js)如下:

CSS页面样式文件(style.css)如下:

 1 html, body{
 2     margin : 0px;
 3     width : 100%;
 4     height : 100%;
 5     overflow: hidden;
 6     background-color: #FFFFFF;
 7 }
 8 
 9 #canvasContainer{
10     margin : 0px;
11     width : 100%;
12     height : 100%;
13 }
14 
15 #textInputSpan{
16     position: absolute;
17     color: #000000;
18     font-family: sans-serif;
19 }
