Question

因此，当用户键入done并从那里跳转到另一个名为＆＃34; survey＆＃34;的方法时，我试图打破一个循环。提出一些遗留问题。

这就是我现在所拥有的：

def survey
    puts "For how many years have you had these allergies?"
    name = gets.chomp.to_i

    puts "When was your last allergy reaction?"
    reaction = gets.chomp.to_i
end

def allergies

    puts "Please enter all your allergies. When you are finished, type 'done'."
    allergy = gets.chomp.downcase!

    while allergy != "done"

        # Format the loop so that when the user types 'done'
        # The loop breaks and we go to the 'survey' method

        allergy = gets.chomp.downcase
        survey
        if allergy == "nuts"
            puts "Beware! The food item contains peanuts!"
            break
        end
    end
end

allergies

目前它只是让我输入一个过敏症，然后跳过调查方法。我该如何改变这一点，以便我可以继续输入过敏症，直到我输入＆＃34;坚果＆＃34;或者＆＃34;完成＆＃34;？

Answer 1

尝试if-else声明

def allergies

    puts "Please enter all your allergies. When you are finished, type 'done'."
    allergy = gets.chomp.downcase!

    while allergy != "done"
        if allergy == "nuts"
            puts "Beware! The food item contains peanuts!"
            break
        else
            survey
        end

        allergy = gets.chomp.downcase
    end
end

Answer 2

def survey
    puts "For how many years have you had these allergies?"
    name = gets.chomp.to_i

    puts "When was your last allergy reaction?"
    reaction = gets.chomp.to_i
end

def allergies

    puts "Please enter all your allergies. When you are finished, type 'done'."
    allergy = gets.chomp.downcase!

    while allergy != "done"

        # Format the loop so that when the user types 'done'
        # The loop breaks and we go to the 'survey' method

        allergy = gets.chomp.downcase
        if allergy == "nuts"
            puts "Beware! The food item contains peanuts!"
            break
        elsif allergy == "done"
          survey
        end
    end
end
