shake.js

A custom 'shake' event JavaScript plugin for mobile web browsers using device accelerometer.

Installation

• Download: zip
• NPM: npm install shake.js
• Bower: bower install shake.js
• Git: git clone https://github.com/alexgibson/shake.js

Dependencies

Your web browser must support the devicemotion event for this plugin to work. Shake.js uses built-in feature detection to determine if it can run in your web browser. It will terminate silently on non-supporting browsers.

Setup

For CommonJS using NPM:

var Shake = require('shake.js'); 

For AMD module:

define(['./shake'], function(Shake) {     // ... }); 

In the browser:

<script src="shake.js"></script> 

Next, create a new Shake instance:

var myShakeEvent = new Shake({     threshold: 15, // optional shake strength threshold     timeout: 1000 // optional, determines the frequency of event generation }); 

Start listening to device motion:

myShakeEvent.start(); 

Register a shake event listener on window with your callback:

window.addEventListener('shake', shakeEventDidOccur, false);  //function to call when shake occurs function shakeEventDidOccur () {      //put your own code here etc.     alert('shake!'); } 

You can stop listening for shake events like so:

window.removeEventListener('shake', shakeEventDidOccur, false); 

To stop listening to device motion, you can call:

myShakeEvent.stop();
