@strA="hello <0>"
arr=["no1","world"]

def show(arr)
 p @strA.sub(/<0>/,arr[1])          #输出效果 hello world
end

上面代码错了,帮忙修正!!!

我想要的结果是输出:

[Copy to clipboard] [ - ]

CODE:

arr1 = Array.new
arr1[0]="msg001"
arr1[1]="cai1"
def showmsg( arr=[])
   p arr
 end
showmsg(arr1)

p @strA.sub("<0>","")+arr[1]

[Copy to clipboard] [ - ]

CODE:

class Msg
    def self.Message(arr=[])
      for i in 0..arr.length-2
         arr[0] = arr[0].sub(/<#{i}>/,arr[i+1])
      end
      str1=arr[0]
      return str1
    end
end

掉用:
arr1=["<0> not equal <1> or <2> not big than <3>","hello","hi","99","180"]
str = Msg.Message(arr1)
结果: str = "hello not equal hi or 99 not big than 180"
