在给定的属性 javascript 中迭代给定特定值的对象和过滤器

Question

我在网上查看过，但未能找到有关我所遇到问题的详细答案。我有一个看起来像这样的对象：

 {
"00001": {
    "sid": "00001",
    "oid": "00001",
    "name": "operation 0001 service 1",
    "description": "test operation 000001",
    "returntype": "something",
    "parameters": {
        "00001": {
            "pid": "00001",
            "name": "parameter 00001 operation 0001 service 1",
            "description": "test parameter 000001",
            "type": "something"
        }
    }
},
"00002": {
    "sid": "00002",
    "oid": "00002",
    "name": "operation 0001 service 2",
    "description": "test operation 000001",
    "returntype": "something",
    "parameters": {}
},
"00003": {
    "sid": "00003",
    "oid": "00003",
    "name": "operation 0001 service 3",
    "description": "test operation 000001",
    "returntype": "something",
    "parameters": {}
},
"00004": {
    "sid": "00004",
    "oid": "00004",
    "name": "operation 0001 service 4",
    "description": "test operation 000001",
    "returntype": "something",
    "parameters": {}
},
"00005": {
    "sid": "00005",
    "oid": "00005",
    "name": "operation 0001 service 5",
    "description": "test operation 000001",
    "returntype": "something",
    "parameters": {}
},
"00006": {
    "sid": "00001",
    "oid": "00006",
    "name": "operation 0001 service 6",
    "description": "test operation 000001",
    "returntype": "something",
    "parameters": {}
}
}

我正在尝试遍历对象并能够 return 具有特定 sid 的对象（即 00001）我知道在 javascript 中有一个 for var in obj，但是我不确定如何实现它以获得所需的输出。任何帮助或指导将不胜感激。

Answer 1

递归是要走的路。参见@T.J。克劳德的回答 Loop through nested objects with jQuery

Answer 2

如果您知道这只是一层深度（"sid" 匹配只会在对象的第一层找到并且您也不会搜索嵌套对象），那么它更直接：

function findMatches(data, prop, val) {
    var item, matches = [];
    for (var obj in data) {
        item = data[obj];
        if (item[prop] === val) {
            matches.push(item);
        }
    }
    return matches;
}

var result = findMatches(myData, "sid", "00001");
