- 16. Why is jQuery so dang cool? • jQuery makes writing Javascript almost effortless – DOM selectors! $(“li.navigation”) – Daisy chain events and commands $(“li.navigation”).click(function() { alert(‘You clicked me!’); }).mouseover(function() { alert(‘You moused over me!’); }).css(‘color’, ‘red’); – Automaticly cross-browser compatible (mostly)
- 17. Why is jQuery so dang cool? • jQuery is used…. a lot… by a lot of people. This means: – Extensive cache of plugins and themes that you can straight-up jack from jQuery.com for use in your mobile site. – Quick and easy access to help from websites like stackoverflow.com

- 21. jQuery Mobile: “What It Do?”
- 22. jQuery Mobile: “What It Do?” The company line: “A unified user interface system that works seamlessly across all popular mobile device platforms, built on the rock-solid jQuery and jQuery UI foundation. Focused on a lightweight codebase built on progressive enhancement with a flexible, easily themeable design.”
- 23. jQuery Mobile: “What It Don’t?” ALERT! You should probably stay away from developing with jQuery Mobile for these devices: Blackberry 4.x All older smartphone platforms and feature phones Any device that doesn’t support media queries MeeGo – Originally a target platform, but Nokia decision to relegate this platform to “experimental”, the good folks at jQuery are considering dropping support. Samsung Bada – The project doesn’t currently have test devices or emulators although so far it’s showing good support. No guarantee of future support.
