咖啡脚本不会在页面更改时触发，但适用于页面加载.[导轨 5]

我在我的 rails 项目中使用咖啡脚本，但问题是它仅在我加载(刷新)页面时才有效，而不是在页面呈现时，它也应该适用于页面视图更改.

I am using coffee script in my rails project, but the problem is it works only when i load(refresh) the page instead when the page renders, it should also work on the page view change.

这是我正在使用的脚本:

here is the script i am using:

facebook.js.coffee

jQuery ->
  $('body').prepend('<div id="fb-root"></div>')

  $.ajax
    url: "#{window.location.protocol}//connect.facebook.net/en_US/all.js"
    dataType: 'script'
    cache: true


window.fbAsyncInit = ->
  FB.init(appId: env["app_id"], cookie: true)

  $('#sign_in').click (e) ->
    e.preventDefault()
    FB.login (response) ->
      window.location = '/auth/facebook/callback' if response.authResponse

  $('#sign_out').click (e) ->
    FB.getLoginStatus (response) ->
      FB.logout() if response.authResponse
    true

推荐答案

你可以试试"turbolinks:load":

ready = ->
  $('body').prepend('<div id="fb-root"></div>')

  $.ajax
    url: "#{window.location.protocol}//connect.facebook.net/en_US/all.js"
    dataType: 'script'
    cache: true


window.fbAsyncInit = ->
  FB.init(appId: env["app_id"], cookie: true)

  $('#sign_in').click (e) ->
    e.preventDefault()
    FB.login (response) ->
      window.location = '/auth/facebook/callback' if response.authResponse

  $('#sign_out').click (e) ->
    FB.getLoginStatus (response) ->
      FB.logout() if response.authResponse
    true


$(document).on('turbolinks:load', ready)
