Outputting javascript code instead of something parseable (json probably) seems like a very bad idea. Are you really willing to eval code from a site outside your control?
A simple line-by-line regex loop should be enough to parse this though.
Under the same origin policy, a web page served from server1.example.com cannot normally connect to or communicate with a server other than server1.example.com. An exception is the HTML <script> element.
This is perfect. I've been looking for an easy way to find user location (city, state) based on IP address, without having to scrape a IP lookup service for it.
