How to Fix jQuery's `ready` Event Failure with Rails 4 and Turbo-Links?

jQuery's 'Ready' Event Not Firing After Initial Page Load?

For Rails 4 applications implementing the asset pipeline, the need to manage JS organization arises. Users may encounter issues where jQuery's ready event fails to trigger on subsequent link clicks due to Turbo-Links.

Turbo-Links enhances navigation by performing page transitions without full reloads. This optimization prevents the ready event from firing after the first page load, as subsequent link clicks only update the page's content.

Resolving the Issue

To ensure jQuery events function seamlessly with Turbo-Links, the following approach is recommended:

CoffeeScript Version

ready = ->
  # Place your CoffeeScript code here
$(document).ready(ready)
$(document).on('page:load', ready)
Copy after login

The 'page:load' event is triggered by Turbo-Links and provides a reliable substitute for the ready event.

JavaScript Version

var ready;
ready = function() {
  # Insert your JavaScript code here
};
$(document).ready(ready);
$(document).on('page:load', ready);
Copy after login

Rails 5 Update

For Rails 5, Turbo-Links 5 includes a turbolinks:load event that fires on both initial and subsequent page loads. This simplifies the solution:

$(document).on('turbolinks:load', function() {
  # Add your JavaScript code here
});
Copy after login

By implementing this approach, jQuery events will execute as expected within Rails 4 applications utilizing Turbo-Links.
