It is a bit of a "would you really do that in production?" type hack, but there is a pure JS compile of SQLite3 that you could use: https://github.com/kripken/sql.js/
Possible problems:
* Nearly half an MB of library to add to your project which might be a concern on mobile (~2.1MB uncompressed.
* It handles the whole DB in memory rather than trying to use any sort of local storage as a block store, which pumps up memory use (again, mobile user may particularly find this an issue) and to persist data you have to pickle the whole DB as a single array (which could be a significant performance issue if the data changes regularly and is not very small) and reload it upon new visit.
* Concurrency between multiple tabs/windows is going to be an issue for the same reason.

In Show HN: SQLiteProxy – A Simple HTTP JSON Proxy for SQLiteThis looks very interesting.
I recently had to teach a series of workshops on SQL and I was trying to figure out the best system to allow students to independently work with small datasets without having to install any software. I found Alon Zakai's absolutely fantastic version of SQLite in JavaScript here:
https://github.com/kripken/sql.js
I coupled that library with a CodeMirror editor and got a working web based environment very quickly.
