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。

以上这些都不适合我,我没有使用jQuery的$(document)来解决这个问题。ready,但使用addEventListener代替。

document.addEventListener("turbolinks:load", function() {
  // do something
});

其他回答

$(document).ready(ready)  

$(document).on('turbolinks:load', ready)

以上这些都不适合我,我没有使用jQuery的$(document)来解决这个问题。ready,但使用addEventListener代替。

document.addEventListener("turbolinks:load", function() {
  // do something
});

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)

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);

以下是我所做的,以确保事情不会执行两次:

$(document).on("page:change", function() {
     // ... init things, just do not bind events ...
     $(document).off("page:change");
});

我发现使用jquery-turbolinks gem或组合$(document)。Ready和$(document).on("page:load")或使用$(document).on("page:change")本身的行为会出乎意料——尤其是在开发过程中。
