Rails Jquery不适用于其他页面

I believe jQuery doesn't work on other pages than the one you just installed. For example, when I type localhost:3000/, in the '/' directory all jQuery works. But when I click to a link created by Rails as

我相信jQuery不能在你刚刚安装的页面上工作。例如，当我键入localhost：3000 /时，在'/'目录中所有jQuery都可以工作。但是当我点击Rails创建的链接时

<%= link_to "Example Link", news_path %>

The page correctly loads, but the jQuery doesn't work. My jQuery codes are as stated:

页面正确加载，但jQuery不起作用。我的jQuery代码如下所述：

$(function() {
  console.log( "pageloaded" );
  ....
  $('.up').click(function(){
    .....
  });
});

3 个解决方案

#1

In Rails 4 turbolinks is active by default.
That means, that $(document).ready() is not executed, when you load a new page.

在Rails 4中，默认情况下，turbolinks处于活动状态。这意味着，当您加载新页面时，$（document）.ready（）不会被执行。

turbolink fires a new event page:load. You can use this to run your javascript code:

turbolink触发一个新的事件页面：加载。您可以使用它来运行您的JavaScript代码：

$(document).on('page:load', your_start_function);

There is an excelent rails cast on turbolinks

在turbolinks上有一个优秀的轨道

https://github.com/kossnocorp/jquery.turbolinks

This gem binds jQuery.ready function with Turbolinks listen event page:load, therefore the solution is supposed to be solved if you are using Turbolinks with Rails 4

这个gem将jQuery.ready函数绑定到Turbolinks监听事件页面：load，因此如果你使用Turbolinks和Rails 4，解决方案应该会被解决

#3

You need gem 'jquery-rails' in your Gemfile (then bundle install if you're using bundler)

您需要在Gemfile中使用gem'jquery-rails'（如果使用的是Bundler，则需要捆绑安装）

Once that's done, you need to require it in your application.js file:

完成后，您需要在application.js文件中要求它：

//= require jquery

Last, you need to ensure that the application.js file is loaded as part of the application template. In application.html.erb you should have the following:

最后，您需要确保将application.js文件作为应用程序模板的一部分加载。在application.html.erb中，您应该具有以下内容：

<%= javascript_include_tag "application" %>

I believe that this is all there by default in a Rails install so if you have removed any of these settings you'll need to add them back to get it to work.

我相信在Rails安装中默认情况下就是这样，所以如果您已经删除了这些设置中的任何一个，则需要将它们添加回来以使其正常工作。
