Ruby仿js的object

SailCat

其实我也不知道能有啥用……
而且ruby没有undefined（熟悉js的应该知道这和null不太一样）只好用nil了

RUBY 代码复制

class JObject < Hash
 
  def method_missing(symbol, *args)
    if symbol.to_s[-1] == ?=
      self[symbol.to_s[0..-2].to_sym]= args[0]
    elsif keys.include?(symbol)
      self[symbol]
    else
      nil
    end
  end
end
 
c = JObject.new
c.str = 1
c.dex = 2
c.int = 3
c.def = "4"
p c      #{:str=>1, :dex=>2, :int=>3, :def:=4}
p c.str  # 1
p c.dex  # 2
p c.int  # 3
p c.def  # "4"
p c.mdf  # nil
c.sub = JObject.new
c.sub.r = 5
p c.sub.r # => 5
c.func = Proc.new {p c.str}
c.func.call #＝> 1

class JObject < Hash


 


  def method_missing(symbol, *args)


    if symbol.to_s[-1] == ?=


      self[symbol.to_s[0..-2].to_sym]= args[0]


    elsif keys.include?(symbol)


      self[symbol]


    else


      nil


    end


  end


end


 


c = JObject.new


c.str = 1


c.dex = 2


c.int = 3


c.def = "4"


p c      #{:str=>1, :dex=>2, :int=>3, :def:=4}


p c.str  # 1


p c.dex  # 2


p c.int  # 3


p c.def  # "4"


p c.mdf  # nil


c.sub = JObject.new


c.sub.r = 5


p c.sub.r # => 5


c.func = Proc.new {p c.str}


c.func.call #＝> 1

话说我刚发了一个多背包，不过xp弄起来似乎麻烦一些，你要不要看一下？

不如直接定义在hash里，就完全一样了2333
