javascript - 将对象重组为二维数组对象

Question

我想将疼痛对象重组为二维数组对象。

最初，我有这样的东西:

{ 
   "education_histories.0.school":[ 
      "The education_histories.0.school field is required."
   ],
   "education_histories.0.degree":[ 
      "The education_histories.0.degree field is required."
   ],
   "education_histories.1.school":[ 
      "The education_histories.1.school field is required."
   ],
   "education_histories.1.degree":[ 
      "The education_histories.1.degree field is required."
   ],
}

我想将其重组为:

[ 
   { 
      "school":[ 
         "The education_histories.0.school field is required."
      ],
      "degree":[ 
         "The education_histories.0.degree field is required."
      ]
   },
   { 
      "school":[ 
         "The education_histories.1.school field is required."
      ],
      "degree":[ 
         "The education_histories.1.degree field is required."
      ]
   }
]

目前，我一直在尝试做这样的事情:

let validationErrors = []    

$.each(this.errors, (key, value) => {
  let splitKey = key.split('.')

  validationErrors[splitKey[1]] = { [splitKey[2]]: value }
})

当然，这不会起作用，因为它一直覆盖到最后一轮。输出如下:

    [ 
       {
          "degree":[ 
             "The education_histories.0.degree field is required."
          ]
       },
       {
          "degree":[ 
             "The education_histories.1.degree field is required."
          ]
       }
    ]

我希望我能做类似的事情

let validationErrors = []    

$.each(this.errors, (key, value) => {
  let splitKey = key.split('.')

  validationErrors[splitKey[1]][splitKey[2]] = value
})

但这也行不通。它说“TypeError:无法设置未定义的属性'school'”

任何帮助将不胜感激。

你不必做太多改变。如果该对象不存在，则创建它，否则只需设置其属性。您还可以使用对象解构，并且不需要 jQuery:

  let validationErrors = []    

 for(const [key, value] of Object.entries(this.errors)) {
    let [ , index, name] = key.split('.');

    if(!validationErrors[index]) valudationErrors[index] = {};
    validationErrors[index][name] = value;
}
