如何在ERB模板中输入回车空格？
通过使用 sinatra，我想生成一个 webVTT，它考虑了空格，以制作一个相同的返回文件，例如：
WEBVTT
1
00:00:22.865 --> 00:00:30.413
Now we are gonna focus on the hihats, and this is where you actually get to hold these sticks. And
2
00:00:30.416 --> 00:00:37.745
I play matched grip which is where your both the sticks are held in the same way, a lot of people called traditional grip,
我编写了以下代码，迭代从 json 转换的哈希对象：
WEBVTT
<% @sub_json['data'].each_with_index do |value, index|%>
<%= index+1 %>
<%= value['start'].to_time %>--><%= value['end'].to_time%>
<%= value['en'] %>
<%= %>
<% end %>
结果不起作用，我粘贴从浏览器向vim发出请求并使用 set list! 显示所有空格，似乎所有返回空格都被删除，我想这就是我的代码不起作用的原因
任何人都知道如何添加空格到使代码工作？
by using sinatra and I want generate a webVTT, which take the whitespaces into account, to make a identical return file like:

I play matched grip which is where your both the sticks are held in the same way, a lot of people called traditional grip,
I made the following code, with iterate a hash object converted from json:
WEBVTT
<% @sub_json['data'].each_with_index do |value, index|%>
<%= index+1 %>
<%= value['start'].to_time %>--><%= value['end'].to_time%>
<%= value['en'] %>
<%= %>
<% end %>
the result doesn't work, I paste the request from browser to vim and use set list! to show all the whitespaces, it seems all the return whitespaces are removed, I guess this is the reason that my code doesn't work
anyone know how to add whitespaces to make the code working?

这可能是 Sinatra 评估 ERB 的方式存在问题。通常，您的代码中会有空格，并且您必须使用类似
<%= some code -%>的内容来删除尾随空格（请注意尾随破折号）。 Sinatra 可能会更改默认的 trim_mode< /a> 评估 ERB 时。不过，你必须深入挖掘内部结构才能找到答案。This might be a problem with the way Sinatra is evaluating the ERB. Normally your code would have the whitespaces there, and you would have to use something like
<%= some code -%>to remove trailing whitespace (notice the trailing dash). Sinatra may change the default trim_mode when evaluating the ERB. You'd have to dig around in the internals to find that out, though.您是否在initializers/mime_types.rb中将vtt注册为mime类型？实际上，这是一个 Rails 文件，但我猜你必须为 Sinatra 做类似的事情。
Did you register vtt as a mime type in initializers/mime_types.rb? Actually, that's a Rails file, but I'd guess you have to do something similar for Sinatra.
