Rails 3. simple_format 不将结果包装在段落标签中

Question

如何让 simple_format 不将返回值包装在 p 标签中？

simple_format "<span class="required">*</span>"

Answer 1

Unfortunately -- you can't. If you check out the source at http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html#method-i-simple_format you'll see that the p tags are wrapped around the content unconditionally.

You could create a helper that uses the simple_format code, but modify it to not include the p tags...

Answer 2

You can specify wrapper_tag option.

simple_format 'Hello', {}, wrapper_tag: 'span'

This code will be:

<span>Hello</span>

Answer 3

Probably not what you really wanted, but... I ended up doing this:

module ApplicationHelper
  def nl2br s
    split_paragraphs(sanitize(s, tags: [])).join('<br>').html_safe
  end
end

UPD Or better this:

def nl2br s
  sanitize(s, tags: []).gsub(/\n/, '<br>').html_safe
end

Answer 4

There's a workaround, if you simply want to get rid of browser-styles:

simple_format "<span class="required">*</span>", {}, wrapper_tag: 'p style="margin: 0"'
