javascript - 如何获取对象的匹配对象数组和json对象

Question

这是我的对象。我只需要访问“oname”:“Fon”和“bid”:1个对象的详细信息。无需访问 "bid": "2"对象详细信息

{
    "oid": "1",
    "oname": "Fon",
    "bun": [{
        "bid": "1",
        "bname": "Ets",
        "dep": [{
            "did": "1",
            "dname": "Dptment",
            "pids": [{
                "pid": "1",
                "st": "active"
            }, {
                "pid": "2",
                "st": "active"
            }]
        }]
    }, {
        "bid": "2",
        "bname": "US",
        "description": "unit2",
        "dep": []
    }]
}

您可以使用filter 方法来获取所需的数据

 var arr = {
            "oid": "1",
            "oname": "Fon",
            "bun": [{
                "bid": "1",
                "bname": "Ets",
                "dep": [{
                    "did": "1",
                    "dname": "Dptment",
                    "pids": [{
                        "pid": "1",
                        "st": "active"
                    }, {
                        "pid": "2",
                        "st": "active"
                    }]
                }]
            }, {
                "bid": "2",
                "bname": "US",
                "description": "unit2",
                "dep": []
            }]
        }

var oname = arr.oname;
var data = arr.bun.filter(function (a) { return a.bid == "1" });
