条件输入值总是返回false（RUBY）

Question

我不知道为什么，即使我键入“Y”的条件总是假

puts "Would you like to continue [y/n]" 
confirm = gets 
puts confirm == "y" # why this is not true even I type "y"  

if confirm == "y" 
    puts "Input is y" 
end 

Answer 1

尝试使用confirm = gets.chomp原因gets设置你到底

与 \n进入

> a = gets 
> y 
=> "y\n" 

Answer 2

请试试此代码。

puts "Would you like to continue [y/n]" 
confirm = gets 
puts "|#{confirm}|" # y\n 
puts confirm.strip == "y" # gives you true 
puts confirm == "y" # gives you false 

if confirm == "y" 
    puts "Input is y" 
end 

你可以使用gets.strip或gets.chomp从gets
