Question

假设我有这样的员工数据

var service = [{
        AssignedEmployeeInternalID: "8000000011",
        AssignedEmployeeUUID: "00000000-0001-1EE1-82C1-8379F1C4462E",
        BillableIndicator: true,
        BusinessPartnerFormattedName: "Sébastien Brun",
        EndDateTime: null,
        EndDatetimeZoneCode: "UTC",
        Info: "-N/A",
        InternalID: "",
        ObjectID: "00163E0E46241EE988E20C5E4033E0BE",
        ParentObjectID: "00163E0306801ED287F1C8E9CDFA9E4A",
        PeriodPlansArray: [],
        PlannedWorkQuantity: "0.00000000000000",
        PlannedWorkQuantityunitCode: "HUR",
        PlannedWorkQuantityunitCodeText: "",

    },
    {
        AssignedEmployeeInternalID: "8000000011",
        AssignedEmployeeUUID: "00000000-0001-1EE1-82C1-8379F1C4462E",
        BillableIndicator: false,
        BusinessPartnerFormattedName: "Sébastien Brun",
        EndDateTime: null,
        EndDatetimeZoneCode: "UTC",
        Info: "-N/A",
        InternalID: "",
        ObjectID: "00163E0E46241EE988E20C5E4033E0BE",
        ParentObjectID: "00163E0306801ED287F1C8E9CDFA9E4A",
        PeriodPlansArray: [],
        PlannedWorkQuantity: "0.00000000000000",
        PlannedWorkQuantityunitCode: "HUR",
        PlannedWorkQuantityunitCodeText: "",

    },
    {
        AssignedEmployeeInternalID: "8000000011",
        AssignedEmployeeUUID: "00000000-0001-1EE1-82C1-8379F1C4462E",
        BillableIndicator: true,
        BusinessPartnerFormattedName: "Sébastien Brun",
        EndDateTime: null,
        EndDatetimeZoneCode: "UTC",
        Info: "-N/A",
        InternalID: "",
        ObjectID: "00163E0E46241EE988E20C5E4033E0BE",
        ParentObjectID: "00163E0306801ED287F1C8E9CDFA9E4A",
        PeriodPlansArray: [],
        PlannedWorkQuantity: "0.00000000000000",
        PlannedWorkQuantityunitCode: "HUR",
        PlannedWorkQuantityunitCodeText: "",
    }
]

如何验证AssignedEmployeeInternalID在所有数组中是否相同？

到目前为止，我想到了这个：

result =  _.differenceBy(service, [{ 'AssignedEmployeeInternalID': "8000000011" }], 'AssignedEmployeeInternalID');

但是如果我没有要排除的值（我事先不知道AssignedEmployeeInternalID值）怎么办

我要动态验证属性是否相同

Answer 1

如果您按如下所示使用Array every方法，则可以在普通JavaScript中完成此操作：

var service = [{
        AssignedEmployeeInternalID: "8000000011",
        AssignedEmployeeUUID: "00000000-0001-1EE1-82C1-8379F1C4462E",
        BillableIndicator: true,
        BusinessPartnerFormattedName: "Sébastien Brun",
        EndDateTime: null,
        EndDatetimeZoneCode: "UTC",
        Info: "-N/A",
        InternalID: "",
        ObjectID: "00163E0E46241EE988E20C5E4033E0BE",
        ParentObjectID: "00163E0306801ED287F1C8E9CDFA9E4A",
        PeriodPlansArray: [],
        PlannedWorkQuantity: "0.00000000000000",
        PlannedWorkQuantityunitCode: "HUR",
        PlannedWorkQuantityunitCodeText: "",

    },
    {
        AssignedEmployeeInternalID: "8000000011",
        AssignedEmployeeUUID: "00000000-0001-1EE1-82C1-8379F1C4462E",
        BillableIndicator: false,
        BusinessPartnerFormattedName: "Sébastien Brun",
        EndDateTime: null,
        EndDatetimeZoneCode: "UTC",
        Info: "-N/A",
        InternalID: "",
        ObjectID: "00163E0E46241EE988E20C5E4033E0BE",
        ParentObjectID: "00163E0306801ED287F1C8E9CDFA9E4A",
        PeriodPlansArray: [],
        PlannedWorkQuantity: "0.00000000000000",
        PlannedWorkQuantityunitCode: "HUR",
        PlannedWorkQuantityunitCodeText: "",

    },
    {
        AssignedEmployeeInternalID: "8000000011",
        AssignedEmployeeUUID: "00000000-0001-1EE1-82C1-8379F1C4462E",
        BillableIndicator: true,
        BusinessPartnerFormattedName: "Sébastien Brun",
        EndDateTime: null,
        EndDatetimeZoneCode: "UTC",
        Info: "-N/A",
        InternalID: "",
        ObjectID: "00163E0E46241EE988E20C5E4033E0BE",
        ParentObjectID: "00163E0306801ED287F1C8E9CDFA9E4A",
        PeriodPlansArray: [],
        PlannedWorkQuantity: "0.00000000000000",
        PlannedWorkQuantityunitCode: "HUR",
        PlannedWorkQuantityunitCodeText: "",
    }
];

const theSame = service.every(el => el.AssignedEmployeeInternalID === service[0].AssignedEmployeeInternalID);

console.log(theSame);

您可以使用uniqBy（请参阅文档https://lodash.com/docs/4.17.15#uniqBy），然后如果结果数组的length为1，则所有数组项的{{ 1}}：

AssignedEmployeeInternalID

Lodash如果我没有要排除的属性，如何验证属性是否在数组中相等
