I'm basing my code on the PhoneGap Storage API, in which one uses JS to populate a page (innerHTML) from a DB. That works fine! However, I'm at a loss as to how to add a row to that DB from a different HTML page if I move all the DB to an external JS page.

I've had experience with PHP and MySQL, having written an entire web site based on it, but I'm confounded with the use of JS to write to a DB. Can you help steer me in the right direction?

The following code works fine, but it's all on the same page. If I moved the JS to an external page, how would I code the JS/DB query to add a new row to the DB, specifically from a button onClick event?

HTML Code:
