Question

我正在尝试更改说明中的html，以便我打开电子邮件客户端的超链接仍然可用，以及指向Google地图图钉的超链接。我想超链接是白色的，因为背景是蓝色的。请在说明框中查看下面的代码：

  # app/controllers/confirmations_controller.rb
  class ConfirmationsController < Devise::ConfirmationsController
    # Remove the first skip_before_filter (:require_no_authentication) if you
    # don't want to enable logged users to access the confirmation page.
    skip_before_filter :require_no_authentication
    skip_before_filter :authenticate_user!

    # PUT /resource/confirmation
    def update
      with_unconfirmed_confirmable do
        if @confirmable.has_no_password?
          @confirmable.attempt_set_password(params[:user])
          if @confirmable.valid? and @confirmable.password_match?
            do_confirm
          else
            do_show
            @confirmable.errors.clear #so that we wont render :new
          end
        else
          @confirmable.errors.add(:email, :password_already_set)
        end
      end

      if !@confirmable.errors.empty?
        self.resource = @confirmable
      render 'confirmations/show' #Change this if you don't have the views on default path
      end
    end

    # GET /resource/confirmation?confirmation_token=abcdef
    def show
      with_unconfirmed_confirmable do
        if @confirmable.has_no_password?
          do_show
        else
          do_confirm
        end
      end
      unless @confirmable.errors.empty?
        self.resource = @confirmable
      render 'confirmations/show' #Change this if you don't have the views on default path
      end
    end

    protected

   def with_unconfirmed_confirmable
      @confirmable = User.find_or_initialize_with_error_by(:confirmation_token, params[:confirmation_token])
      if !@confirmable.new_record?
        @confirmable.only_if_unconfirmed {yield}
      end
    end

    def do_show
      @confirmation_token = params[:confirmation_token]
      @requires_password = true
      self.resource = @confirmable
      render 'confirmations/show' #Change this if you don't have the views on default path
    end

    def do_confirm
      @confirmable.confirm!
      set_flash_message :notice, :confirmed
      sign_in_and_redirect(resource_name, @confirmable)
    end
  end

Answer 1

这是打开电子邮件客户端的标签

<a href="mailto:webmaster@example.com">Jon Doe</a>

然后对于Google地图页面，您只需要链接到您想要的城市/地点{hm <a href="https://www.google.com/maps/place">A place</a>

Answer 2

您的代码中有一些奇怪的标记。

以下是使用css选择器的工作示例。

a {
   color:#FF0000; // set all hyperlinks to red
}

[href^="mailto"] {
    color:#FFFFFF; // set any hyperlink which starts with mailto in the href to white
}
