JavaScript: how to stop an audio on autoplay by keyboard

I want to know how to stop an audio that is set to "autoplay" using the X key on the keyboard. I have tried in a couple of method but it doesn't work. That's my code:

JavaScript:

var source = "audio/homepage_benvenuto.mp3";
        var audio = document.createElement("audio");
        audio.autoplay = true;
        audio.load()
        audio.addEventListener("load", function() 
        { 
                audio.play();
        }, true);
        audio.src = source;

window.addEventListener("keydown", checkKeyPressed, false);
        function checkKeyPressed(e) 
        {
if (e.keyCode == "88") // 88 = X: interrompe audio in corso
            {
                player.pause();
                player.currentTime = 0;
                document.getElementById('audioA').pause();
            }
}

I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
