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 (){})

其他回答

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。

或者使用

$(document).on "page:load", attachRatingHandler

或者使用jQuery的.on函数来达到同样的效果

$(document).on 'click', 'span.star', attachRatingHandler

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!

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

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
});
