下面直接放测试代码：
index.html
<!DOCTYPE html> <html manifest="m.manifest"> <head> <meta charset=utf-8"> <link rel="stylesheet" href="test.css"> <script type="text/javascript" src="test.js"></script> </head> <body>
<img src="test.png"> <div class="test"></div> </body> </html>
m.manifest
CACHE MANIFEST
#我是注释，这个文件名叫 m.manifest
CACHE:
test.css
test.png
test.js
test.css
.test {min-height:600px; background:#ddd;}
test.js
alert("cache test");
测试通过
