Question

我正在尝试累积数组的属性并将其作为字符串保存回数组，以便稍后使用JSON.parse进行解析。

在初始数据集中，items属性是一个数组。

我想重构数据，使得items是一串对象。

给出类似的东西：

[{
   {
     "n":"1",
     "items": [0: "{"id":"id1","desc":"description1"}",
               1: "{"id":"id2","desc":"description2"}"
               2: "{"id":"id3","desc":"description3"}"]
   },
   {
     "n":"2",
     "items": [0: "{"id":"id4","desc":"description4"}",
               1: "{"id":"id5","desc":"description5"}"
               2: "{"id":"id6","desc":"description6"}"]
   }
}]

转换为：

[{
   {
     "n":"1",
     "items": "[{"id":"id1","desc":"description1"}","{"id":"id2","desc":"description2"}","{"id":"id3","desc":"description3"}]"
   },
   {
     "n":"2",
     "items": "[{"id":"id4","desc":"description4"}","{"id":"id5","desc":"description5"}", "{"id":"id6","desc":"description6"}]"
   }
}]

Answer 1

我必须清理你的数据，所以我会假设我在下面设置的数据结构就是你的实际意思。

＆＃13;

const data = [
  {
    "n":"1",
    "items": [
      {"id":"id1","desc":"description1"},
      {"id":"id2","desc":"description2"},
      {"id":"id3","desc":"description3"}
    ]
  },
  {
    "n":"2",
    "items": [
      {"id":"id4","desc":"description4"},
      {"id":"id5","desc":"description5"},
      {"id":"id6","desc":"description6"}
    ]
  }
];

const newData = data.map(val => {
  return Object.assign({}, val, {
    items: JSON.stringify(val.items)
  });
});

console.log(newData);

Answer 2

  arr.map(({ items, ...rest }) => ({ items: JSON.stringify(items), ...rest }));
