如何实现"getAllChildrenById"方法 [英] How to implement the 'getAllChildrenById' method

问题描述

有这样一个数据数组.如何使用lodash方法_.filter通过parentTd(数组"parentIds"之一)实现过滤?

There is such an array of data. How do I implement filtering by parentTd (one of the array "parentIds"), using lodash method _.filter?

"terms": [{
      "id": 13,
      "name": 'illustrator',
      "parentIds": [2, 4],
      "isCompanyArea": false
    },
    {
      "id": 14,
      "name": 'figma',   
      "parentIds": [2, 3],
      "isCompanyArea": true
    },
    {
      "id": 15,
      "name": 'sas',
      "parentIds": [3 ,4, 2],
      "isCompanyArea": false
    },
    {
      "id": 16,
      "name": 'jmp',
      "parentIds": [3],
      "isCompanyArea": false
    },
    {
      "id": 17,
      "name": 'docker',
      "parentIds": [4, 5],
      "isCompanyArea": false
    }]

推荐答案

您可以将filter与includes结合使用，以过滤出parentIds包含特定ID的条目.

You can use filter in combination with includes to filter out the entries where parentIds contains a certain id.

function filter(id) {
    return _.filter(terms, term => term.parentIds.includes(id));
}

此外，您不需要lodash:

Also, you do not need lodash:

function filter(id) {
    return terms.filter(term => term.parentIds.includes(id));
}
