将 {} 中的新对象添加到数组

Question

我想编辑我的代码以将 {} 新对象添加到按 id 分组的数组中，我的代码将对象添加到我的旧对象中：我的代码和结果是：

result = {

  "field": [{

    "id": "11",

    "name": "name",

    "email": "email"

  }, {

    "id": "11",

    "name": "name",

    "email": "email"

  }, {

    "id": "1234",

    "name": "name",

    "email": "email"

  }]

}

results = result.field;

groups = {};

for (var i in results) {

  var groupName = results[i].id;

  if (!groups[results[i].id]) {

    groups[groupName] = [];

  }

  groups[groupName].push(results[i].name);

  groups[groupName].push(results[i].email);

}

console.log(groups);

我希望结果是这样的：

 {"1234": [

        {"name" : "name",

        "email":"email"},

        {"name":"name",

        "email":"email"}],

     "11":[{"name":"name",

        "email":"email"}]}

** 我使用 wso2，所以我不能使用任何方法，例如： reduce 。谢谢 ..

Answer 1

我终于做到了，答案是：result = {  "field": [{    "id": "11",    "name": "asma",    "email": "asma@hotmail"  }, {    "id": "11",    "name": "jone",    "email": "jone@hotmail"  }, {    "id": "1234",    "name": "jak",    "email": "jak@hotmail"  }]}results = result.field;groups = {};for (var i in results) {  var groupName = results[i].id;  if (!groups[results[i].id]) {    groups[groupName] = [];  } groups[groupName].push({"name" :results[i].name,"email":results[i].email})}console.log(groups);

Answer 2

您可以简单地使用reduce()方法：var object = { "field": [  {"id":"11","name":"name","email":"email"},{"id":"11","name":"name","email":"email"},{"id":"1234","name":"name","email":"email"}]};var result = object.field.reduce((acc, {id, ...rest})=>{    acc[id] = acc[id] || [];    acc[id].push({...rest});    return acc;},{});console.log(result);
