Demo

Install

Install using npm:

npm i pattern-lock-js --save 

... or install using yarn:

yarn add pattern-lock-js 

Getting started

Import dependecies:

<script src="jquery.js" charset="utf-8"></script>

Import the module:

<link rel="stylesheet" href="patternlock.min.css"> <script src="patternlock.min.js" charset="utf-8"></script>

Design your desired svg pattern (or use the default one below). Your svg graphics must as a minimum have the patternlock class and three groups <g> with the classes lock-actives, lock-lines and lock-dots

<svg class="patternlock" id="lock" viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg">     <g class="lock-actives"></g>     <g class="lock-lines"></g>     <g class="lock-dots">         <circle cx="20" cy="20" r="2"/>         <circle cx="50" cy="20" r="2"/>         <circle cx="80" cy="20" r="2"/>          <circle cx="20" cy="50" r="2"/>         <circle cx="50" cy="50" r="2"/>         <circle cx="80" cy="50" r="2"/>          <circle cx="20" cy="80" r="2"/>         <circle cx="50" cy="80" r="2"/>         <circle cx="80" cy="80" r="2"/>     </g> </svg>

Initialise the component

var lock = new PatternLock("#lock", {   onPattern: function(pattern) {     // Context is the pattern lock instance     console.log(pattern)    } });

Options

The returned object from new PatternLock(...) has the following utility functions:

  • clear() Clears the current pattern
  • success() Validates the pattern as correct
  • error() Validates the pattern as incorrect
  • getPattern() Returnes the currently active pattern or NaN

The pattern lock constructor accepts a second argument - an object literal with the following properties:

  • onPattern: function Called when a pattern is drawn with the pattern as argument. Returning true/false validates/invalidates the pattern - the same as calling success() and error(). The context is set to the pattern lock instance itself.
  • vibrate: boolean Defines if there should be vibrations while using the PatternLock (if available). Default: true
