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。

当前回答

我发现当使用ready和turbolinks的函数时，我的函数翻了一番:load，所以我使用，

var ready = function() {
  // you code goes here
}

if (Turbolinks.supported == false) {
  $(document).on('ready', ready);
};
if (Turbolinks.supported == true) {
  $(document).on('turbolinks:load', ready);
};

这样，如果支持涡轮链接，您的函数就不会加倍!

其他回答

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

$(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

你必须使用:

document.addEventListener("turbolinks:load", function() {
  // your code here
})

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

我想我把这个留给那些升级到Turbolinks 5的人:修复代码的最简单的方法是从:

var ready;
ready = function() {
  // Your JS here
}
$(document).ready(ready);
$(document).on('page:load', ready)

to:

var ready;
ready = function() {
  // Your JS here
}
$(document).on('turbolinks:load', ready);

我通常为我的rails项目做以下工作:

在application.js

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

然后在其余的.js文件中，我调用onInit(function(){})而不是使用$(function (){})
