Facebook SDK and rails 4 Turbolinks

问题:

I'm having a hard time trying to load fast the javascript Facebook SDK into my rails 4 application. Is there a good way to make it work correctly with turbolinks?

if i add this code on my JS application assets. It's not working properly due to turbolinks:

<div id="fb-root"></div> <script>   window.fbAsyncInit = function() {     // init the FB JS SDK     FB.init({       appId      : 'YOUR_APP_ID',                        // App ID from the app dashboard       channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel file for x-domain comms       status     : true,                                 // Check Facebook Login status       xfbml      : true                                  // Look for social plugins on the page     });      // Additional initialization code such as adding Event Listeners goes here   };    // Load the SDK asynchronously   (function(d, s, id){      var js, fjs = d.getElementsByTagName(s)[0];      if (d.getElementById(id)) {return;}      js = d.createElement(s); js.id = id;      js.src = "//connect.facebook.net/en_US/all.js";      fjs.parentNode.insertBefore(js, fjs);    }(document, 'script', 'facebook-jssdk')); </script> 

thanks

You will find the proper solution for integrating the Facebook SDK with Turbolinks here :

I was having a problem with the Like Box not loading when I navigate between pages using turbo links. My solution was to create a social.js.coffee in my assets/javascripts folder. In this file it simply has

$(document).on 'page:change', ->   FB.init({ status: true, cookie: true, xfbml: true }); 

I know its a lot to put in it's own file ;-), but the idea was that I know google analytics, twitter, and others will have the same conflicts and this will be a nice place to house those solutions as well.

Quoting this answer

If you prefer to use native Turbolinks 5 events, you can add this script to your Rails assets:

// FacebookSDK // https://developers.facebook.com/docs/plugins/page-plugin/ (function(d, s, id) {   var js, fjs = d.getElementsByTagName(s)[0];   if (d.getElementById(id)) return;   js = d.createElement(s);   js.id = id;   js.src = "//connect.facebook.net/ja_JP/sdk.js#xfbml=1&version=v2.8";   fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk')); // Replace 'facebook-jssdk' with your page id.  // Compatibility with Turbolinks 5 (function($) {   var fbRoot;    function saveFacebookRoot() {     if ($('#fb-root').length) {       fbRoot = $('#fb-root').detach();     }   };    function restoreFacebookRoot() {     if (fbRoot != null) {       if ($('#fb-root').length) {         $('#fb-root').replaceWith(fbRoot);       } else {         $('body').append(fbRoot);       }     }      if (typeof FB !== "undefined" && FB !== null) { // Instance of FacebookSDK       FB.XFBML.parse();     }   };    document.addEventListener('turbolinks:request-start', saveFacebookRoot)   document.addEventListener('turbolinks:load', restoreFacebookRoot) }(jQuery));

If you're putting your Facebook JS code at the end of your view, use flush in your controller action to ensure it's fully reloaded properly with Turbolinks:

def show   # ...   render :show, flush: true end 

Worked like a charm.

I followed the solution suggested by @gallonallen with some small modification. just created a file called turbo.js with following content:

$(document).on('turbolinks:load', function() {      FB.init({ status: true, cookie: true, xfbml: true });  }); 

And added //= require turbo in application.js before //= require query and it started working for me. I am using rails 4.2.6 and ruby 2.3.1 with turbo links 5. For me, prior to fix, turbo links was working on my local but not when deployed to staging or prod.
