Rails 4:如何在涡轮链接中使用$(document).ready()

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。

与其使用变量保存“ready”函数并将其绑定到事件，不如在page:load触发时触发ready事件。

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

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...

});

我发现下面的文章对我来说非常有用，并详细介绍了以下用法:

var load_this_javascript = function() { 
  // do some things 
}
$(document).ready(load_this_javascript)
$(window).bind('page:change', load_this_javascript)

$(document).on 'ready turbolinks:load', ->
  console.log '(document).turbolinks:load'

测试了这么多的解决方案，终于得出了这个结论。你的代码肯定不会被调用两次。

var has_loaded = false; Var ready = function() { 如果(! has_loaded) { has_loaded = true; // YOURJS ｝｝ $(文档)时(准备); 美元(文档)。绑定(“页面:改变”,准备);
