Konami Code implementation for Dojo Framework. Eventually it will change to be more general.

KonamiCode.js

//  KONAMI CODE:  ↑   ↑   ↓   ↓   ←   →   ←   →   B   A
var konamiCode = [38, 38, 40, 40, 37, 39, 37, 39, 98, 97];
var index = 0;
 
window.onkeypress = function(e) {
    
    var keyPressed = (e.charCode != 0 ? e.charCode : e.keyCode);
    
    if (keyPressed == konamiCode[index]) {
        index++;
        if (index == konamiCode.length) {
            console.log("OK Konami Code");
            index = 0;
        }
    } else {
        console.log("Restart Konami Code");
        index = 0;
    }
};
