将 json 数组缩减为 json 对象答案

【问题标题】：Reduce array of json to json object将 json 数组缩减为 json 对象

【问题描述】：

我有详细信息

data = {
  name: "charles",
  id: "1",
  education: [
    {"class": "X","marks": 223,"percentage": "59%"},
    {"class": "IX","marks": 223,"percentage": "59%"},
    {"class": "IIX","marks": 223,"percentage": "59%"},
    {"class": "IIIX","marks": 223,"percentage": "59%"}
  ]
}

我想要的结果需要分解成 4 个 json 对象

{name:"charles",id:"1", education:{"class":"X","marks":223,"percentage":59%}}
{name:"charles",id:"1", education:{"class":"IX","marks":223,"percentage":59%}}

谁能告诉我如何实现它？

我成功地循环和创建每个对象，如下所示：

this.data.education.forEach( class => {
        const newData: any = {};
        newData.name= data.name;
        newData.id= data.id;
        newData.education = class ;
array.push(newData);
});

I am looking for any simplist way of achieving it?

【问题讨论】：

问题中没有 JSON，因为 JSON 是一种文本序列化格式。显示的代码是“JavaScript”（和 Object Literal 语法）。请参阅json.org，并适当更新标题/标签/措辞。

标签： arrays json angular

【解决方案1】：

您需要提取 name 和 id 并传递 Education 数组的所有条目。希望这会有所帮助

const data = { name: "charles", id: "1", education: [
    { "class": "X", "marks": 223, "percentage": 59 },
    { "class": "IX", "marks": 223, "percentage": 59 },
    { "class": "IIX", "marks": 223, "percentage": 59 },
    { "class": "IIIX", "marks": 223, "percentage": 59 }
  ]
};
const {name, id} = data;
const response = data.education
  .reduce((result, education) => ([...result, {name, id, education}]), []);

console.log(response)

【解决方案2】：

const newData = data.education
               .map(e => ({ id: data.id, name: data.name, education: e}))
