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。
注意:请参阅@SDP的答案,以获得一个干净的内置解决方案
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');
});
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。
