javascript - 如何将过滤器应用于 JavaScript 中的 JSON 数组？

Question

我从我的控制器得到这个结果，并想捕捉一些物品。让我们看一些代码：

```
[
    {
    "id": 17,
    "corretora_id": 1,
    "user_id": 2,
    "order": null,
    "nome": "Johnny English",
    "telefone": "(11)0070-0070",
    "celular": "(00)70070-0700",
    "email": "[e-mail]",
    "obs": "É o homem mais burro do mundo. Mas quer o plano mais caro do Mundo  porque ele é rico",
    "img_lead": "1534353433.png",
    "created_at": "2018-08-15 17:17:14",
    "updated_at": "2018-08-15 21:30:48",
    "atendimentos": [
        {
        "id": 22,
        "lead_id": 17,
        "dataAgendamento": "2018-08-16 09:00:00",
        "user_id": 2,
        "comentarios": "Realmente é o homem mais burro do mundo. QUer um plano  de saúde para agentes secretos em nome de 007.\nPediu pra ligar amanhã",
        "created_at": "2018-08-15 20:48:07",
        "updated_at": "2018-08-15 20:48:07"
        },  
        {
        "id": 27,
        "lead_id": 17,
        "dataAgendamento": "2018-08-17 12:00:00",
        "user_id": 2,
        "comentarios": "Teste",
        "created_at": "2018-08-17 18:49:36",
        "updated_at": "2018-08-17 18:49:36"
        },
        {
        "id": 28,
        "lead_id": 17,
        "dataAgendamento": "2018-08-25 19:34:00",
        "user_id": 2,
        "comentarios": "Esse tem que estar em cima quando reload",
        "created_at": "2018-08-18 14:28:24",
        "updated_at": "2018-08-18 14:28:24"
        }
    ]
},
```

我需要读取 obj id:17 中的所有项目以及“atendimentos”节点内的子项目，如“lead_id”和“dataAgenmento”。

我该怎么做？

首先你需要展平数组，试试这个功能：

flatten(arr, result = []){
    for (var i = 0, length = arr.length; i < length; i++) {
      var value = arr[i];
      if (Array.isArray(value)) {
        flatten(value, result);
      } else {
        result.push(value);
      }
    }
    return result;
  }
