我正在使用backbone.localstorage 用来做 草稿功能，可以保存文字，但是如何将图片保存到草稿中呢？如果使用base64的话，大图片比如10M就不好处理了，大家有没有什么建议？
There's no workaround. Storage quota is a hard limit.
However, for binary data I would recommend IndexedDB instead of localStorage, for several reasons:
- You can save binary data directly (no need to convert to base64), which saves 33% of quota.
- This also helps to get rid of the performance overhead of conversion.
- According to a test, in some browsers (e.g. Firefox), IndexedDB have more storage quota compared to
localStorage. - IndexedDB provides an asynchronous API, which is important when you read a big chunk of data that takes time.
存url，再获取，没有网络给默认的
