如何在节点

Question

我如何通过关键字获取对象。 我也希望在对象名称中获得包含“_score”的对象值 我尝试Object.key（）但它没有得到孩子

我有这个对象

const data : {
    name : "johny",
    lname : "walker",
    a_score : 30,
    b_score : 40,
    result : {
                 c_score : 50,
                 d_score : 60
             }
}

我如何返回此数据

{ 
    a_score : 30, 
    b_score :40, 
    c_score :50,
    d_score :60
}

Answer 1

您可以使用reduce()方法为此创建递归函数。

const data = {"name":"johny","lname":"walker","a_score":30,"b_score":40,"result":{"c_score":50,"d_score":60}}

const pick = (obj, key) => {
  return Object.keys(obj).reduce((r, e) => {
    if (typeof obj[e] == 'object') Object.assign(r, pick(obj[e], key))
    if (e.includes(key)) r[e] = obj[e]
    return r;
  }, {})
}

console.log(pick(data, '_score'))
