javascript - 使用 javascript/jquery 在较大对象中查找对象及其属性

Question

family = {
  'person1':[{"id":"1111","name":"adam", "sex":"male", "born":"USA"}],
  'person2':[{"id":"2222","name":"sarah", "sex":"female", "born":"Canada"}],
  'person3':[{"id":"3333","name":"adam", "sex":"male", "born":"USA"}]
};

鉴于上面的家庭对象，如何提取具有特定 id(或姓名)值的人员对象之一的所有属性(id、姓名、性别、出生)？例如id=1111

所以理想情况下我可以获得一个可以操作的新对象 personInQuestion，其中:

personInQuestion = {"id":"1111","name":"adam", "sex":"male", "born":"USA"}

Answer 1

循环遍历对象，并抓取匹配的元素。

var search = 1111;

var personInQuestion = {};
for(var x in family){
    var item = family[x][0];
    if(item.id == search){
        personInQuestion = item;
        break;
    }
}
