对于网络应用程序来说，最佳的大容量本地存储选项是什么？
我正在使用 jquery mobile 构建一个网络应用程序，该应用程序将有大量需要缓存以供离线访问的图像，并且我正在寻找实现此目的的最佳方法。
我本来只是想为图像创建一个缓存清单文件，但是数量太多，并且超出了大小限制。我也考虑过Indexeddb，但它似乎还没有太多支持。
该解决方案需要适用于 Android 和 iOS，并且还可以在 Web 浏览器中访问。总存储容量可能需要大约 15-20 MB。有一个好的选择吗？
另外，我对网络应用程序没有太多经验，因此您可以提供的任何示例都会很棒。
I'm building a web app using jquery mobile that will have lots of images that need to be cached for offline access, and I'm looking for the best way to accomplish this.
I originally was just going to create a cache manifest file for the images, but there are too many, and they exceed the size limit. I also considered Indexeddb, but it doesn't seem to have much support yet.
The solution needs to work for both Android and iOS and also be accessible in a web browser. Total storage capacity will probably need to be around 15-20 MB. Is there a good option for this?
Also, I don't have much experience with web apps, so any examples you could provide would be great.

Web SQL 数据库 (sqlite) 将为您提供 50MB 本地存储空间，适用于 Android 和 iOS

这里有一个很好的库可以简化对 sqlite 的访问

我认为对此没有什么好的解决方案。即使您使用并组合多种存储方法（包括标准浏览器缓存），您仍然不会接近 15MB。
我担心这将归结为专用应用程序和不在本地存储图像之间的选择。
I don't think there is any good solution for this. Even if you use and combine multiple storage methods (including the standard browser cache) you still won't get near to 15MB.
I fear this is going to come down to a choice between a dedicated app, and not storing the images locally.
