keycode

Simple map of keyboard codes.

Installation

$ component install timoxley/keycode

Example

var keycode = require('keycode');
document.addEventListener('keydown', function(e) {
  console.log("You pressed", keycode(e))
})

API

keycode tries to make an intelligent guess as to what you're trying to discover based on the type of argument you supply.

##keycode(keycode:Event)

Returns the name of the key associated with this event.

document.body.addEventListener('keyup', function(e) {
  console.log(keycode(e)) // prints name of key
})

Due to the keypress event being weird,keycode currently does not support the keypress event, but this should not be an issue as keydown and keyup work perfectly fine.

##keycode(keycode:Number)

Returns the lowercase name of a given numeric keycode.

keycode(13) // => 'enter'

##keycode(name:String)

Returns the numeric keycode for given key name.

keycode('Enter') // => 13

// keycode is not case sensitive
keycode('eNtEr') // => 13

Name Aliases

Common aliases are also supplied:

> for (var alias in keycode.aliases) { console.log(alias, keycode(keycode(alias))) }
ctl ctrl
pause pause/break
break pause/break
caps caps lock
escape esc
pgup page up
pgdn page up
ins insert
del delete
spc space

Maps

Key code/name maps are available directly as keycode.codes and keycode.names respectively.

keycode.names[13] // => 'enter'
keycode.codes['Enter'] // => 13
