All codes here are not complicated, so you can easily understand even though you are still students in school. To benefit your learning, we will provide you download link to a zip file thus you can get all source codes for future usage.

CORDOVA JQUERY ROULETTE
How to rotate an image in Cordova APPs. Truly, it is similar to that in browser. Completely tested HTML and JavaScript codes in browser on developing mode can be moved to Cordova APPs directly.
jQueryRotate Library
We introduce an example created by a jQuery extension called jQueryRotate.js, and convert it into a Cordova APP. This example is a Roulette Wheel game. Our previous post has talked about it in details and written about where the jQueryRotate.js library come from.
Using jQuery Mobile
To build a Cordova APP from HTML and JavaScript, you had better add the jQuery Mobile project to make it be responsive in web design. We leverage jQuery Mobile Pages here to embed whole Roulette Wheel game into pages.
Don’t Use CDN in Cordova
We consider compatibility and choose jQuery Mobile 1.4.5 and jQuery 1.11.1 together, but don’t use CDN in Cordova APPs. Just download it in advance.
Build a Cordova APP
Roulette Wheel Game App Games
Cordova CLI command lines can fulfill the building process from creating to final building. For arguments in creating, the roulette is PATH, com.easycodeshare.roulette is ID, and Roulette is human readable NAME.
Replace content of the folder roulette/www with all downloaded source codes, and then issue the final command to build an APP.

SECTION 2
JQUERYROTATE.JS EXAMPLE
jQueryRotate.js consists of basic 3 methods, rotate(), getRotateAngle(), and StopRotate(). Roulette example will lead you to understand it.
The Basics
Below the a JavaScript object method function roul.rotate() in this roulette example. It calls $('#turntable').rotate() by jQuery to start rotating based on jQueryRotate.js library.
For the meanings of angle, animateTo, and duration, refer to the previous post about roulette, how to rotate a roulette picture on click using jQuery.
Roulette Wheel Layout
Clicking on the roulette wheel forces it to turn for a while. When stopped, upper pointer indicate gained prize which is also shown on a text field.
Getting Prizes
JavaScript object prize calculates a randomly generated prize for each rotating. There are 37 slots, and each slot has a corresponding prize in mapping.
Stop Roulette Wheel
Stopping is an optional action. Of course, you can suddenly stop it. At that time, it will show a random angle, rather than a prize.
