Add Konami Code (Or Custom Cheat Code) To Webpage- jQuery jKonamiCode

Yet another keypress cheat code plugin that adds the familiar Konami Code or any pre-defined key sequence to your webpage. 

You're able to assign the Konami Code to any actions you prefer (for example: Easter egg on the webpage).

How to use it:

1. Include the JavaScript jKonamiCode.js after loading jQuery JavaScript library.

<script src="https://code.jquery.com/jquery-1.12.4.min.js" 
        integrity="sha384-nvAa0+6Qg9clwYCGGPpDQLVpLNn0fRaROjHqs13t4Ggj3Ez50XnGQqc/r8MhnRDZ" 
        crossorigin="anonymous"></script>
<script src="jKonamiCode.js"></script>

2. Execute a function when the user types the correct Konami Code (Up Up Down Down Left Right Left Right B A).

$(function(){
  $(window).jKonamicode(function(){
    alert("Hello World!");
  });
});

3. To create a custom cheat code, define a sequence of keystrokes using JavaScript Keycodes.

$(function(){
  $(window).jKonamicode({
    {
      code:[38,38,40,40,37,39,37,39,66,65],
    },
     function(){
      alert("Hello World!");
     }
  );
});

4. Execute a function each time you press the right key.

$(function(){
  $(window).jKonamicode({
    {
      code:[38,38,40,40,37,39,37,39,66,65],
      onRightKey:function(e){
        alert("You entered "+e+" right keys.");
      }
    },
     function(){
      alert("Hello World!");
     }
  );
});
