Ask keystrokes by name.
Whichkey.js simply translates keystroke codes to readable names. Like when you want to know if a keystroke was any letter or a specific one, or if it was an arrow key, or anything else; you simply ask it by its name.
Simply wrap a keypress, keyup or keydown event in whichkey(), for instance:
input.addEventListener('keydown', function(e) {
var key = whichkey(e);
});Then proceed to ask which key was pressed. Like this:
if (key.escape) {...}
if (key.backspace) {...}
if (key.letter) {...}
if (key.a) {...}
if (key.arrow) {...}
if (key.down) {...}So far I've added the following queries:
esc[ape]tabbackspacedeletespace[bar]enter|return<any number>number[s]<any letter>letter[s]arrow[s]leftuprightdownhomeendpageUppageDown
More queries will be added over time, but you can always help by adding a couple yourself and submitting a Pull request.
