I ran into an issue in my Rails 4 app while trying to organize JS files "the rails way". They were previously scattered across different views. I organized them into separate files and compile them with the assets pipeline. However, I just learned that jQuery's "ready" event doesn't fire on subsequent clicks when turbo-linking is turned on. The first time you load a page it works. But when you click a link, anything inside the ready( function($) { won't get executed (because the page doesn't actually load again). Good explanation: here.
所以我的问题是:什么是确保jQuery事件在涡轮链接打开时正常工作的正确方法?您是否将脚本包装在特定于rails的侦听器中?或者也许rails有某种魔力，使它变得不必要?文档对这应该如何工作有点模糊，特别是关于通过manifest(s)加载多个文件，如application.js。
我是这么做的…
CoffeeScript:
ready = ->
...your coffeescript goes here...
$(document).ready(ready)
$(document).on('page:load', ready)
最后一行监听页面加载，这是什么涡轮链接将触发。
编辑……添加Javascript版本(每个请求):
var ready;
ready = function() {
...your javascript goes here...
};
$(document).ready(ready);
$(document).on('page:load', ready);
编辑2…对于Rails 5 (Turbolinks 5)页面:load变成了Turbolinks:load，甚至会在初始加载时触发。所以我们可以这样做:
$(document).on('turbolinks:load', function() {
...your javascript goes here...
});

根据新的rails指南，正确的方法是这样做:
$(document).on('turbolinks:load', function() {
console.log('(document).turbolinks:load')
});
或者在coffeescript中:
$(document).on "turbolinks:load", ->
alert "page has loaded!"
不监听事件$(document)。就绪后，只会触发一个事件。没有惊喜，不需要使用jquery。turbolinks宝石。
这不仅适用于rails 5，而且适用于rails 4.2及以上版本。
