如何创建与 Ruby/Sinatra 交互的 jquery 加载器？

我有一个简单的网站抓取工具，正在练习用 Ruby + Sinatra + Nokogiri 构建它。

我有一个名为的加载程序，它半透明地覆盖整个屏幕。

截至目前，页面初始加载时的设置如下（通常在初始加载时的任何给定时间页面上都会有大量数据）

$(window).load(function() {
    $('#loading').fadeOut();
    $('#wrapper').fadeIn();
});

我的问题是，是否可以激活此加载器，然后'当 nokogiri 工作时，在我的 ruby 脚本中取消激活它？

例如，在...

post '/refresh' do
  # scraping code here that can take seconds to minutes
end

我想在开始时启用加载程序，然后在最后禁用它。不知道我会如何去做这件事，但任何帮助将不胜感激！

I have a simple website scraper that I'm practicing on building in Ruby + Sinatra + Nokogiri.

I have a loader called that semi-transparently covers up the entire screen.

As of right now, its set to the following for when the page initially loads (usually theres a large amount of data on the page at any given time when its loaded initially)

$(window).load(function() {
    $('#loading').fadeOut();
    $('#wrapper').fadeIn();
});

My question is, is it possible to activate this loader and then 'unactivate' it during my ruby script while nokogiri is working?

For example, in...

post '/refresh' do
  # scraping code here that can take seconds to minutes
end

I want to enable the loader at the beginning, then disable it at the end. Not sure how I would go about doing this, but any help would be appreciated!
