Using the Konami code, easily configure and Easter Egg for your page or any element on the page.

Parameters

  • code Personalized code.
  • cheat The callback function to fire once the cheat code has been entered.
  • eventName jQuery event name for default callback
  • eventProperties event property override for default callback

Installation

bower install konami-code

Instructions

Include the plugin in the header of your page:

	<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>`
	<script src="jquery.konami.js" type="text/javascript"></script>

With callback

Apply the plugin to a selector to capture keypresses:

  $( window ).konami();

  $( '.konami-sensitive' ).konami();

Specify a callback to fire once the code has been entered:

  $( window ).konami({
		cheat: function() {
			alert( 'Cheat code activated!' );
		}
	});

Using jQuery events

Catch the konami code with a jQuery event handler:

  $( window ).konami();
  $( window ).on('konami', function() {
    alert( 'Cheat code activated!' );
  })

Add extra data to the jQuery event callback:

  $( window ).konami( { message: 'special message' } );
  $( window ).on('konami', function(evt, extraParam) {
    alert( 'Cheat code activated: ' + extraParam.message + '!' );
  })

Use event names:

  $('.type1').konami( { eventName: 'konami.on.type1' } );
  $('.type2').konami( { eventName: 'konami.on.type2' } );
  $( window ).on('konami.on.type2', function(evt, extraParam) {
    alert( 'Cheat code activated on a type2 element' );
  })

Personallizing the code

You can personalize the code too, just entering a array with ASCII codes keys in code param

  $( window ).konami({
  		code : [38,38,40,40,37,39,37,39], // up up down down left right left right
		cheat: function() {
			alert( 'Cheat code activated!' );
		}
	});
