如何在Rails 3.2.8中使用Jquery? [英] How can I use Jquery in rails 3.2.8?

问题描述

我阅读的所有教程都告诉我使用"public/javascripts"文件夹.但是在Rails 3.2.8中没有这样的文件夹

All the tutorials I've read tell me to use the "public/javascripts" folder. But there is no such folder in rails 3.2.8

• 我在哪里放置我的jquery代码?
• Rails 3.2.8中不包含Jquery吗?

推荐答案

默认的Rails应用程序(> 3.2)在Gemfile的第23行包含jQuery gem:

The default Rails application (> 3.2) includes the jQuery gem on line 23 of the Gemfile:

gem 'jquery-rails'

您将jQuery代码放在自定义JavaScript文件(例如hello.js)中的以下路径中:

You place your jQuery code in a custom JavaScript file--e.g., hello.js--in the following path:

app/assets/javascripts/

示例:

app/assets/javascripts/hello.js

在hello.js中，确保在此块中包含jQuery代码:

In hello.js, make sure you include your jQuery code inside of this block:

$(document).ready(function() {
    YOUR CODE HERE
});

就是这样.您已经准备在Rails中使用jQuery. (由于app/assets/javascripts/application.js中的第15行，因此可以正常工作)

That's it. You're ready to use jQuery in Rails. (This works because of line 15 in app/assets/javascripts/application.js)

//= require_tree .

此行说要包括javascripts目录中的所有内容.

This line says to include everything in the javascripts directory.
