您可能知道JQM 1.4.1。现在包括两组图标：PNG和SVG。在以前的版本中，所有图标都包含在单个文件中(如：icons-18-black.png)，这很容易包含在HTML5的缓存和离线使用手册中。
我的问题是：
我应该声明我的html5缓存清单中提供的每个图标吗？包括PNG和SVG？
如果我只申报PNG呢？。我的JQM离线应用程序还会工作吗？还是会因为找不到SVG而崩溃？
如果是这样，我的HTML5清单将增长到：

如果是这样的话。我的离线应用程序将这些文件传输到三星Galaxy 3时会延迟1分钟以上。
这对我的用户来说时间太长了！！！
我遇到了和你一样的问题。事实证明，这些svg图像实际上并没有被使用，您不需要包含它们。svg图像在css文件中内联编码。
出于我的目的，我只需要支持内联svg的浏览器，所以我不需要在清单中包括png文件或svg文件。对内联svg的支持非常好：http://caniuse.com/svg-html5
所以也许你也可以逃脱惩罚。
这个链接的帖子很好地总结了这个有点令人困惑的场景，但我已经将相关部分复制粘贴到这里，以便于参考。
标准jquery.mobile.icons-1.4.0.css包括SVG图标内部在CSS文件中，但引用的images目录PNG文件。
jquery.mobile-1.4.0.css只是标准图标、主题和结构css文件的串联。
jquery.mobile.external-png-1.4.0.css是一个组合文件，引用images目录中的png文件。它不使用SVG图标。
jquery.mobile.inline-pg-1.4.0.css是一个组合文件，在css文件中内部包含png图标。它不需要图像目录它也根本不使用SVG图标。
jquery.mobile.inline-svg-1.4.0.css是一个组合文件，在css文件中内部包含svg图标。它不使用PNG图标全部的
其他组合也是可能的，可以单独加载CSS部分，也可以自己进行简单的串联。这是一个问题决定是否支持SVG、PNG或两者(回退到PNG当浏览器不支持SVG时)以及是否要包含CSS文件本身中的内联图像或从图像中引用它们目录
默认的组合文件在大多数情况下最有意义。SVG图标以内联方式加载在CSS文件中。这些图标被大多数浏览器使用。如果用户的浏览器没有支持SVG，那么他们在CSS文件。但这只会影响到极少数用户。在里面在这种情况下，PNG图标将从images目录加载。它不必要地给绝大多数用户带来负担是没有意义的包括内联在CSS文件内的PNG图标。
有趣的是，尽管单独的SVG图标包含在images/SVG中，但没有提供引用它们的CSS。
