keycode
Simple map of keyboard codes.
Installation
npm
$ npm install keycode
component
$ 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,keycodecurrently 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 down
ins insert
del delete
spc space
keycode.isEventKey(event: Event, nameOrCode: String | Number)
Tests if an keyboard event against a given name or keycode.
Will return true if the event matches the given name or keycode, false otherwise.
// assume event is an keydown event with key 'enter'
keycode.isEventKey(event, 'enter') // => true
keycode.isEventKey(event, 'down') // => false
keycode.isEventKey(event, 13) // => true
keycode.isEventKey(event, 40) // => false
Maps
Key code/name maps are available directly as keycode.codes and keycode.names respectively.
keycode.names[13] // => 'enter'
keycode.codes['enter'] // => 13
