javascript - 如何使用 javascript 查找 json 中的通用名称对象

转载作者：行者123 更新时间：2023-12-01 01:17:35

我正在寻找 json 逻辑 2 小时，但没有找到任何解决方案。我的 json 数据如下所示:

这确实是一个很大的文件，所以我粘贴了其中的一些。我怎样才能找到所有具有共同姓氏的人(这意味着 json 数据的共同名字)？

我在 javascript 中使用 ajax 请求。

最佳答案

您可以使用reduce()并按名称对ID进行分组，

const data = [

  }
];

const result = data.reduce((all, curr) => {
  (all[curr.name.first] = all[curr.name.first] || []).push(
  curr["_id"]
  );

  return all;
}, {});

const formattedResult = Object.entries(result).map(([name, ids]) => ({
  name,
  ids,
  repeated : ids.length,  
}));

console.log(formattedResult);

// for top 5 repeated names : 
const topFive = formattedResult.sort((a,b) => b.repeated - a.repeated).slice(0, 5);

生成的对象将以name作为键，并以相同名称的相应值的ids(我修改了您的输入为了演示而使用第二个名称)
