使用 lodash 的紧凑对象数组

Question

我有一个对象数组，比如第一个 json。

基于属性名称，我想将 zip 这个数组放在另一个数组中，就像那样。 如果名称与另一个 object 相同，则编译 object 并将其他属性和值设置为字段数组。

[ 
   { 
      "name":"D1D1",
      "attritube":"HOST_NAME",
      "value_inv":"TEST1",
      "value_prod":"TESTA1"
   },
   { 
      "name":"D1D1",
      "attritube":"HOST_NAME",
      "value_inv":"TEST2",
      "value_prod":"TESTB1"
   },
   { 
      "name":"D2D2",
      "attritube":"COMMENTS",
      "value_inv":"TEST1",
      "value_prod":"TESTA1"
   }
]




[ 
   { 
      "name":"D1D1",
      "fields":[ 
         { 
            "attritube":"HOST_NAME",
            "value_inv":"TEST1",
            "value_prod":"TESTA1"
         },
         { 
            "attritube":"HOST_NAME",
            "value_inv":"TEST2",
            "value_prod":"TESTB1"
         }
      ]
   },
   { 
      "name":"D2D2",
      "fields":[ 
         { 
            "attritube":"COMMENTS",
            "value_inv":"TEST1",
            "value_prod":"TESTA1"
         }
      ]
   }
]

这不是很漂亮，当你有一个非常大的数据集时它不会表现得很好，但它是功能性的并且产生你期望的 output。

 const arr = [ { "name":"D1D1", "attritube":"HOST_NAME", "value_inv":"TEST1", "value_prod":"TESTA1" }, { "name":"D1D1", "attritube":"HOST_NAME", "value_inv":"TEST2", "value_prod":"TESTB1" }, { "name":"D2D2", "attritube":"COMMENTS", "value_inv":"TEST1", "value_prod":"TESTA1" } ]; const newArr = _.chain(arr).groupBy('name').toPairs().map((val) => ({ name: val[0], fields: _.map(val[1], (v) => _.omit(v, ['name'])) })).value(); console.log(newArr);
