所以我在写一个web应用程序，需要存储〜离线数据的40MB的脱机Web SQL数据库。它需要在浏览器（桌​​面），Safari浏览器（台式和移动）和Android的浏览器工作。现在我知道该Web SQL是支持这些浏览器，我知道因为哪个版本，但我需要知道有多少存储是允许的。 Safari浏览器的桌面支持数据库存储500MB。移动Safari浏览器支持数据库存储50MB。

So I am writing a web app that needs to store ~40MB of offline data in a offline Web SQL database. It needs to work in Chrome (desktop), Safari (desktop and mobile) and android's browser. Now I know that Web SQL is supported in these browsers and I know since which versions but i need to know how much storage is allowed. Safari desktop supports 500MB of database storage. Safari mobile supports 50MB of database storage.

不过，我已经花了几个小时的时间到处搜寻，希望找出空间铬Desktop支持，什么是Android浏览器的支持，但无法找到任何具体。一个地方提到的硬5MB的限制铬台式机，而另一个引用了25MB的限制铬台式机（不使用Chrome扩展）。一位消息人士对Android的浏览器注意到一个15MB的限制又指出一个5MB的限制。任何人都可以，指出什么是Android和Chrome Web的SQL​​存储实际的硬性限制点我到什么地方？

However I have spent literally hours searching everywhere to find out what space chrome desktop supports and what the android browser supports but cannot find anything concrete. One place noted a hard 5MB limit for chrome desktop while another quoted a 25MB limit for chrome desktop (without using a chrome extension). One source for android's browser noted a 15MB limit another noted a 5MB limit. Can anyone point me to somewhere that states what the actual hard limits on Web SQL storage are for android and chrome??

推荐答案

请参阅此链接，谷歌浏览器：

See this link for Google Chrome:

HTTP：//$c$c.google.com/铬/扩展/ manifest.html＃权限

默认为5MB，但你可以切换unlimitedStorage属性

Default is 5MB, but you can switch the unlimitedStorage property
