Using HTML5 localStorage as a fallback for offline form submission (miniapps.co.uk)

The hardest part is the UI. Should the data in storage expire? Should the client be notified when the form is submitted? Should the user be able to cancel the submitting? To answer all of those in a way that every user understands is not easy.

Thanks, I was just thinking about this exact problem and wondering if localStorage would be a good way to handle it. It looks dead simple from your code - just set an attribute with the JSON request as the value, and try to send it later. Lots of little other things to work out like tommi mentioned, but nice simple examples are really helpful.

Pretty cool, the only thing I can think of is letting the user know when the form isn't submitted, and telling them what the app will do once it's back online.

i would be careful right now with storing data on clients after those flash cookie law suits this and last month.
