Javascript 如何添加和删除 2 层深度的 JSON 元素

Question

我在 google 上搜索并反复研究如何从 JSON 对象中删除元素。

这是我的简化 JSON，用于说明我的要求。

捆绑:

{
    "resourceType": "Bundle",
    "meta": {
        "lastUpdated": "2017-10-06T04:42:22.411Z"
    },
    "type": "searchset",
    "total": "0",
    "entry": [
        {
            "_id": "59d5739e668e9e3fd29aeb0d",
            "resource": {
                "id": "59d5739e668e9e3fd29aeb0d"
            },
            "__v": 0
        },
        {
            "_id": "59d6a3fae4b45d50c5ffd4f7",
            "resource": {
                "id": "59d6a3fae4b45d50c5ffd4f7"
            },
            "__v": 0
        },
        {
            "_id": "59d6a831e4b45d50c5ffd4fa",
            "resource": {
                "id": "59d6a831e4b45d50c5ffd4fa"
            },
            "__v": 0
        }
    ]
}

如何删除所有entry._id和entry.__v？ 我尝试过这些，但不起作用。

delete bundle.meta;   <-- meta is on level 1, it works.
delete bundle.entry._id; <-- not working. The _id under entry
delete bundle.__v; <-- not working. The __v is also under entry

如何在每个条目下添加新元素，例如下面的“fullname”

我想要的结果 - 删除“_id”和“__v”，然后将“fullname”添加到条目[]中:

{
    "resourceType": "Bundle",
    "meta": {
        "lastUpdated": "2017-10-06T04:42:22.411Z"
    },
    "type": "searchset",
    "total": "0",
    "entry": [
        {
            "fullname": "Apple",
            "resource": {
                "id": "59d5739e668e9e3fd29aeb0d",
            }
        },
        {
            "fullname": "Orange",
            "resource": {
                "id": "59d6a3fae4b45d50c5ffd4f7"
            },
        }, ......

我尝试了很多方法，也用谷歌搜索了很多。感谢您的帮助!

感谢维韦克的回答。它有效。

for (var i = 0; i < bundle.entry.length; i++) {
    delete bundle.entry[i]._id;
    delete bundle.entry[i].__v;
    bundle.entry[i].fullname = "Test";
}

请尝试下面的代码。测试了一下可以帮到你。

  var object1 = {
    "resourceType": "Bundle",
    "meta": {
        "lastUpdated": "2017-10-06T04:42:22.411Z"
    },
    "type": "searchset",
    "total": "0",
    "entry": [
        {
            "_id": "59d5739e668e9e3fd29aeb0d",
            "resource": {
                "id": "59d5739e668e9e3fd29aeb0d",
            },
            "__v": 0
        },
        {
            "_id": "59d6a3fae4b45d50c5ffd4f7",
            "resource": {
                "id": "59d6a3fae4b45d50c5ffd4f7"
            },
            "__v": 0
        },
        {
            "_id": "59d6a831e4b45d50c5ffd4fa",
            "resource": {
                "id": "59d6a831e4b45d50c5ffd4fa"
            },
            "__v": 0
        }
    ]
  };

  var array1=['Apple','Orange','Gava']

  function a(){
        for(var i=0;i<object1.entry.length;i++){
            delete object1.entry[i]._id;
            delete object1.entry[i].__v;
            object1.entry[i].fullname = array1[i];
        }
        console.log(object);
  }
