How to show the remaining space of the localStorage?

Question

I'm creating a webapp which uses the localStorage.

I would like to show something like: X % is used over Y Megabytes

How to calculate that?

Regards.

IE has a proprietary propery "window.localStorage.remainingSpace" which returns the remaining space in bytes. Unfortunately can't find similar functionality in any of the other browsers.

I think that this will help you out Calculating usage of localStorage space

There is no way to query to browser for that exact information

What they are doing in that answer is constantly writing to LocalStorage until it fills up, that way they know how much space there is – JoshStrange Dec 20 '11 at 14:35
