如何在Rails中包含CoffeeScript

Question

那么自3.1以来CoffeeScript已经附带了Rails？太棒了!我正在进入语法.我喜欢简单.

然而,我似乎无法弄清楚如何将它包含在我的网站上.我试过把它包括在内,但是没有用.

我有一个.erb文件我想要这个,new.html.erb(显然,这是一个Rails应用程序):

<script type="text/coffeescript">
# Countdown to date script provided by JavaScriptKit.com
# http://www.javascriptkit.com/script/script2/count.shtml

montharray=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec")

countdown(yr,m,d) ->
  today=new Date()
  todayy=today.getYear()

if (todayy < 1000)
  todayy+=1900
  todaym=today.getMonth()
  todayd=today.getDate()
  todaystring=montharray[todaym]+" "+todayd+", "+todayy
  futurestring=montharray[m-1]+" "+d+", "+yr

  difference=(Math.round((Date.parse(futurestring)-Date.parse(todaystring))/(24*60*60*1000))*1)

if (difference==0) and document.write(current)
  elseif (difference>0) document.write("ONLY "+difference+" DAYS LEFT!")

countdown(2012,4,30)

</script>?

它根本没有显示出来.想法？

如果您启用了CoffeeScript,Rails将为.js.coffee您的每个控制器生成一个文件app/assets/javascripts.这就是您的CoffeeScript所属的地方,您不需要包含script标签.
