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。
在Rails 4文档中找到了这个，类似于DemoZluk的解决方案，但略短:
$(document).on 'page:change', ->
# Actions to do
OR
$(document).on('page:change', function () {
// Actions to do
});
如果你有调用$(document).ready()的外部脚本，或者如果你不想重写所有现有的JavaScript，那么这个gem允许你继续使用$(document).ready()和TurboLinks: https://github.com/kossnocorp/jquery.turbolinks

我修改如下:
确保你在其他依赖于应用程序的js文件被包括之前，通过改变包括顺序，如下所示:
// in application.js - make sure `require_self` comes before `require_tree .`
//= require_self
//= require_tree .
在application.js中定义一个处理绑定的全局函数
// application.js
window.onLoad = function(callback) {
// binds ready event and turbolink page:load event
$(document).ready(callback);
$(document).on('page:load',callback);
};
现在你可以绑定如下内容:
// in coffee script:
onLoad ->
$('a.clickable').click =>
alert('link clicked!');
// equivalent in javascript:
onLoad(function() {
$('a.clickable').click(function() {
alert('link clicked');
});
