Question

我有辅助功能

 def link_to_user(text, user, options = {})
options[:class] = options.has_key?(:class) ? "#{options[:class]} user-link" : ""
content_tag :span, :class => :vcard do
  link_to(text, user, options) +
  content_tag(:span, :style => "display: none;", :class => "userbox") do
    content_tag(:span, :class => "fn") do
      content_tag(:span, :class => "given-name") do user.firstname
       end +
      content_tag(:span, :class => "family-name") do #user.lastname 
       end
    end 
  end
end

端

现在我正在尝试添加div元素作为vcard span的兄弟。我试过，但我得到错误的语法错误，意外的'+'，期待kEND（SyntaxError）

请提出建议

Answer 1

你试过了吗？

@content = content_tag :span, :class => :vcard do
    link_to(text, user, options) +
    content_tag(:span, :style => "display: none;", :class => "userbox") do
      content_tag(:span, :class => "fn") do
        content_tag(:span, :class => "given-name") do user.firstname
        end +
        content_tag(:span, :class => "family-name") do #user.lastname 
        end
      end 
    end
  end
@content << content_tag(:div, "etc")

Answer 2

首先，将参数传递给块的语法是

method_call do |arg|

你错过了管道（|）

其次，您错过了end

在rails中添加div元素
