$ ->
   window.app.helpers = new class Helpers

    constructor: (@name) ->
      @slideRecipeId     = $("#slideRecipe")
      @specialities      = ["A", "B", "C"]

      setTimeout @countUpRecipes, 3000

    countUpRecipes: ->
      @slideRecipeId.html(@specialities[Math.floor(Math.random() * @specialities.length)])

问题是在加载时我收到以下错误：

Uncaught TypeError: Cannot read property 'length' of undefined

代码有什么问题？谢谢。

调用时需要绑定上下文@countUpRecipes：

setTimeout => 
    @countUpRecipes
, 3000
