【问题描述】：

我的JSON：

{ "question_1": 
  { "type"  : "string"
  , "title" : "1. 1. What did he want to make for dinner?"
  , "enum": 
    [ " a.) He wanted to make some salad and spaghetti"
    , " b.) He wanted to make some pasta salad"
    ] 
  , "required": false
  } 
, "question_2": 
  { "type": "string"
  , "title": "2. 2. Did he have the ingredients to make dinner?"
  , "enum": 
    [ " a.) Yes, he had the ingredients"
    , " b.) No, he didn't have the ingredients"
    ] 
  , "required": false
  } 
, "question_3": 
  { "type"  : "string"
  , "title" : "3. 3. Where did he go shopping?"
  , "enum": 
    [ " a.) He went to Albertsons"
    , " b.) He went to Albertos"
    ] 
  , "required": false
  } 
}

在我的 json 中有很多数字彼此相邻并且重复

例如：

1. 1. => 1.
2. 2. => 2.
3. 3. => 3.

等等

我怎样才能删除这个重复？

我想删除 json 中彼此相邻的重复数字

【问题讨论】：

这看起来不像 JSON（应该是一个字符串），它看起来像一个 JavaScript 对象字面量。但是，除此之外，是什么导致了数字的重复，是否可以解决这个问题而不是事后整理？

【解决方案1】：

您可以使用正则表达式替换它，使用分组引用将确保您不会删除像“1. 2.”这样的数字：

const data = { "question_1": 
  { "type"  : "string"
  , "title" : "1. 1. What did he want to make for dinner?"
  , "enum": 
    [ " a.) He wanted to make some salad and spaghetti"
    , " b.) He wanted to make some pasta salad"
    ] 
  , "required": false
  } 
, "question_2": 
  { "type": "string"
  , "title": "2. 2. Did he have the ingredients to make dinner?"
  , "enum": 
    [ " a.) Yes, he had the ingredients"
    , " b.) No, he didn't have the ingredients"
    ] 
  , "required": false
  } 
, "question_3": 
  { "type"  : "string"
  , "title" : "3. 3. Where did he go shopping?"
  , "enum": 
    [ " a.) He went to Albertsons"
    , " b.) He went to Albertos"
    ] 
  , "required": false
  } 
}

Object.values(data).forEach(v => v.title = v.title.replace(/(d). +./, '$1.'))
console.log(Object.values(data).map(v => v.title))
