Javascript Char Codes (Key Codes)

In most the browser there are three possible kinds of events triggered when a keyboard key is pressed or released:

• keydown
• keypress
• keyup

Whenever a KeyboardEvent triggered, you can check which key was pressed or released because that event contains information which you can write logic against.

    document.addEventListener("keydown", function(event) {
    console.log(event.which);
    console.log(event.keyCode);
    console.log(event.shiftKey);
    console.log(event.altKey);
    console.log(event.ctrlKey);
    console.log(event.metaKey);
    }
