Angular Directive for limiting number input fields to maximum characters

do ->
  'use strict'

  LimitTo = () ->
    return {
      restrict: "A"
      link: (scope, element, attrs) ->
        limit = parseInt(attrs.limitTo)

        element.on 'keydown', (event) ->
          return if event.keyCode == 8

          if @value.length == limit
            event.preventDefault()
            return
        return
    }

  LimitTo.$inject = []

Sorry I just write coffeescript, you can always use this amazing tool js2.coffee, to get the javascript version of the code.
