Rails 5: how to use $(document).ready() with turbo-links

问题

Turbolinks prevents normal $(document).ready() events from firing on all page visits besides the initial load, as discussed here and here. None of the solutions in the linked answers work with Rails 5, though. How can I run code on each page visit like in prior versions?

回答1:

Rather than listen to the ready event, you need to hook in to an event fired by Turbolinks for every page visit.

Unfortunately, Turbolinks 5 (which is the version that appears in Rails 5) has been re-written, and does not use the same event names as in previous versions of Turbolinks, causing the answers mentioned to fail. What works now is to listen to the turbolinks:load event like so:

$( document ).on('turbolinks:load', function() {
  console.log("It works on each visit!")
})

回答2:

Native JS :

document.addEventListener("turbolinks:load", function() {
    console.log('It works on each visit!');
});

回答3:

This is my solution, override jQuery.fn.ready, then $(document).ready works without any change:

jQuery.fn.ready = (fn)->
  $(this).on 'turbolinks:load', fn

回答4:

In rails 5 the easiest solution is to use:

$(document).on('ready turbolinks:load', function() {});

Instead of $(document).ready. Works like a charm.

回答5:

Here is solution that work for me, from here:

1. install gem 'jquery-turbolinks'

2. add this .coffee file to your app: https://github.com/turbolinks/turbolinks/blob/master/src/turbolinks/compatibility.coffee

3. name it turbolinks-compatibility.coffee

4. at application.js

   //= require jquery
   //= require jquery_ujs
   //= require jquery.turbolinks
   //= require turbolinks
   //= require turbolinks-compatibility

While we await the fix to this really cool gem, I was able to move forward by modifying the following;

  addCallback: (callback) ->
if $.turbo.isReady
  callback($)
$document.on 'turbo:ready', -> callback($)

to:

  addCallback: (callback) ->
if $.turbo.isReady
  callback($)
$document.on 'turbolinks:load', -> callback($)

I'm not yet aware what this does not resolve, but it seemed to work well on initial inspection.

回答7:

(For coffeescript)

I Use: $(document).on 'turbolinks:load', ->

Instead of: $(document).on('turbolinks:load', function() {...})

回答8:

Use the light-weight gem jquery-turbolinks.

It makes $(document).ready() work with Turbolinks without changing existing code.

Alternatively, you could change $(document).ready() to one of:

$(document).on('page:fetch', function() { /* your code here */ });

$(document).on('page:change', function() { /* your code here */ });

depending on which one is more appropriate in your situation.
