Typescript不支持诸如Java中的扩展枚举。您可以使用一个类实现类似的效果：
interface EnumIdentity { }class Status implements EnumIdentity { private static AllValues: { [name: string] : Status } = {}; static readonly Active = new Status(1, "Active"); static readonly AwaitingReview = new Status(2, "Awaiting Review"); static readonly Closed = new Status(3, "Closed"); static readonly Complete = new Status(4, "Complete"); static readonly Draft = new Status(5, "Draft"); static readonly InProcess = new Status(6, "In Process"); static readonly InReview = new Status(7, "In Review"); static readonly NotStarted = new Status(8, "Not Started"); static readonly PendingResolution = new Status(9, "Pending Resolution"); static readonly Rejected = new Status(10, "Rejected"); private constructor(public readonly id: number, public readonly displayValue: string) { Status.AllValues[displayValue] = this; } public static parseEnum(data: string) : Status{ return Status.AllValues[data]; }}
