将此代码放入clients.js.coffee并刷新浏览器后没有任何反应，然后我由本地服务器重新启动，也没有任何反应，我该怎么办？

客户.js.coffee

jQuery ->
  $('#client_street_id').parent().hide()
  street = $('#client_street_id').html()

  $('#client_city_id').change ->
    city = $('#client_city_id :selected').text()
    escaped_city = city.replace(/([ #;&,.+*~\':"!^$[\]()=>|\/@])/g, '\\$1')
    options = $(street).filter("optgroup[label='#{escaped_city}']").html()

    if options
      $('#client_street_id').html(options)
      $('#client_street_id').parent().show()
    else
      $('#client_street_id').empty()
      $('#client_street_id').parent().hide()

应用程序.js

固定缩进。

每个 -> 后应缩进 2 个空格，直到您希望关闭该函数。

还有http://js2coffee.org/用于基本转换（只是给你一个想法）

jQuery ->
  $('#client_street_id').parent().hide()
  street = $('#client_street_id').html()
  $('#client_city_id').change ->
    city = $('#client_city_id :selected').text()
    escaped_city = city.replace(/([ #;&,.+*~\':"!^$[\]()=>|\/@])/g, '\\$1')
    options = $(street).filter("optgroup[label='#{escaped_city}']").html()
    if options
      $('#client_street_id').html(options)
      $('#client_street_id').parent().show()
    else
      $('#client_street_id').empty()
      $('#client_street_id').parent().hide()
