Javascript 我有一个json数组对象，我必须比较大多数节点的子节点，并返回只有该特定子节点的完整数组对象

上面提到的json数组对象就是我的全部

应该将所有子节点与“name”：“永恒火焰”进行比较，我应该得到满足该条件的子节点的输出

const jsonArray = {
     "squadName": "Super hero squad",
     "homeTown": "Metro City",
     "formed": 2016,
     "secretBase": "Super tower",
     "active": true,
     "members": [
      {
      "name": "Molecule Man",
      "age": 29,
      "secretIdentity": "Dan Jukes",
      "powers": [
        "Radiation resistance",
        "Turning tiny",
        "Radiation blast"
     ]
   },
   {
    "name": "Madame Uppercut",
    "age": 39,
    "secretIdentity": "Jane Wilson",
    "powers": [
      "Million tonne punch",
      "Damage resistance",
      "Superhuman reflexes"
     ]
    },
    {
     "name": "Eternal Flame",
     "age": 1000000,
     "secretIdentity": "Unknown",
     "powers": [
       "Immortality",
       "Heat Immunity",
       "Inferno",
       "Teleportation",
       "Interdimensional travel"
      ]
     }
    ]
   }

试图返回数据但不知道哪里出错，请帮助我提前感谢sin

     }
    ]
   }`

首先，您的JSON结构无效（至少是您发布的结构）

我将假设

jsonArray

是一个团队的对象数据，包含成员，您正在搜索一个名为永恒火焰的成员（节点）

其次，您的代码将返回与成员数组长度相同的数组，除了匹配的节点外，该数组的所有位置都是

null

。仅返回匹配节点（即成员）

---

假设每个成员的名称都是唯一的，则可以使用：

const newJson={
…jsonArray，
成员：[jsonArray.members.find（m=>m.name==“永恒的火焰”）]
}

这种方法首先在

newJson

中引入

jsonArray

的数据，然后将

newJson

的

members

属性设置为一个数组，该数组只包含您要查找的成员

如果名称不唯一，则可以使用：

const newJson={
…jsonArray，
成员：jsonArray.members.filter（m=>m.name==“永恒的火焰”）
}

对于您的数据，在这两种情况下，输出为：

jsonArray.members.filter(member => member.name === "Eternal Flame") [0]; // [0] Gets the first item of the matching array (Which should have a count of 1 anyway)

. 没有

const jsonArray={}，{}，

是无效语法

jsonArray.members.filter(member => member.name === "Eternal Flame") [0]; // [0] Gets the first item of the matching array (Which should have a count of 1 anyway)
