javascript - 如何遍历对象数组以查找 ID 然后返回同级键

Question

下面有一个复杂的对象数组，我有一个 term_id 可以搜索。我试图找到匹配的 term_id，然后从我找到 term_id 的同一个对象返回关联的 ticker: name。

container = [Object, Object];

// container:
[
    0: Object {
        tags: [
            0: {
                term: "tag_name_1",
                term_id: 1111
            },
            0: {
                term: "tag_name_2",
                term_id: 2222
            }
        ],
        ticker: {
            name: "ticker1"
        }
    },
    1: Object {
        tags: [
            0: {
                term: "tag_name_3",
                term_id: 3333
            }
        ],
        ticker: {
            name: "ticker2"
        }
    }
]

您将如何实现这一目标？ _lodash 有简单的方法吗？ ？

// You can do this with native JS:

var container = [{tags: [{term: "tag_name_1",term_id: 1111},{term: "tag_name_2",term_id: 2222}],ticker: {name: "ticker1"}},{tags: [{term: "tag_name_3",term_id: 3333}],ticker: {name: "ticker2"}}];

function search (container, id) {
  var contains = false;
  var result;

  container.forEach(function(obj){
    obj.tags.forEach(function(innerData){
      if (innerData.term_id === id) {
        contains = true;
      }
    })
    if (contains) {
      result = obj.ticker.name;
      contains = false;
    }
  });

  return result;
}

console.log(search(container, 1111));
