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)

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

jQuery Mobile: “What It Do?”

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.”

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.
