You want to use the offline application API. These APIs allow to save the data if internet is not available.    Indeed you can use these APIs for your own applications. The following two links will hopefully help you out, http://www.w3.org/TR/offline-webapps/ https://developer.mozilla.org/en-US/Apps/Build/Offline
The only logic is that if you can successfully upload the file to server, you are online. Otherwise you are offline so handle the error events. In error events store the content in offline localStorage! There are no offline database and web browsers won't support your access to database engines. So you should consider using the localStorage API .
