Backup and restore webSQL database with PhoneGap and jQuery

This is a blog about some code I made to backup data from a webSQL data to a local file on your device (Android, iOS or some other, whatever supported by PhoneGap).

It reads the database and writes the content to a text file in JSON format. Restore is obviously the other way around.

Tested on:
- PhoneGap 2.5.0
- jQuery 1.9.1

All the Javascript code can be in a single file (in example: backuprestore.js). It has to be loaded AFTER PhoneGap and AFTER jQuery. Change it to your liking or needs.

It can also be used in addition to jQuery Mobile, but it is not needed.
