我是Rails新手，我的js代码没有运行。我的程序应该在同一页面上输出检查一个数字的回文的结果，而不是切换到一个新的，但是当我按下输出按钮时，什么也没有发生。浏览器中启用了js代码，所有必要的库似乎都已经下载完毕。（不过，你还是可以写信告诉我你需要仔细检查）。浏览器也显示js请求的状态为200。为什么它们不工作？

class PalindromeController < ApplicationController

  def show
    @number = params[:number]
    @error = validate_input(@number)
    calculate_palindrome unless @error

    respond_to do |format|
      format.js 
    end
  end

  def validate_input(number)
    return 'No number entered' if number =~ /\D/
    return 'The number is already a palindrome' if number == number.reverse

    nil

    @number = @number.to_i
    @results = []
