json - 将键值对附加到 json 对象

Question

这是 json 对象 我正在与

{
    "name": "John Smith",
    "age": 32,
    "employed": true,
    "address": {
        "street": "701 First Ave.",
        "city": "Sunnyvale, CA 95125",
        "country": "United States"
    },
    "children": [
        {
            "name": "Richard",
            "age": 7
        },
        {
            "name": "Susan",
            "age": 4
        },
        {
            "name": "James",
            "age": 3
        }
    ]
}

我希望这是另一个键值对:

"collegeId": {
                      "eventno": "6062",
                      "eventdesc": "abc"
                                            }; 

我试过 concat 但结果是 ||符号，我 cdnt 迭代。我使用了溢出但只删除了逗号。

concattedjson = JSON.stringify(JSON.parse(json1).concat(JSON.parse(json2)));

如何将 key 对值添加到现有的 json 对象？
我在 JavaScript 中工作。

这是最简单的方法，它对我有用。

var testJson = {
        "name": "John Smith",
        "age": 32,
        "employed": true,
        "address": {
            "street": "701 First Ave.",
            "city": "Sunnyvale, CA 95125",
            "country": "United States"
        },
        "children": [
            {
                "name": "Richard",
                "age": 7
            },
            {
                "name": "Susan",
                "age": 4
            },
            {
                "name": "James",
                "age": 3
            }
        ]
    };
    testJson.collegeId = {"eventno": "6062","eventdesc": "abc"};
