如何在typescript中访问枚举的名称

我使用的库中有一个emum，如下所示：

/** Defines values that represent the status of a request to purchase an app or add-on. */
enum StorePurchaseStatus {
    /** The current user has already purchased the specified app or add-on. */
    alreadyPurchased = 1,
    /** The purchase request did not succeed because of a network connectivity error. */
    networkError = 3,
    /** The purchase request did not succeed. */
    notPurchased = 2,
    /** The purchase request did not succeed because of a server error returned by the Windows Store. */
    serverError = 4,
    /** The purchase request succeeded. */
    succeeded = 0,
}

StorePurchaseStatus[1]

我有数字值，我想打印姓名ex。我的状态为1，我想打印'alreadyPurchased'

但是，当我这样做时：

/** Defines values that represent the status of a request to purchase an app or add-on. */
enum StorePurchaseStatus {
    /** The current user has already purchased the specified app or add-on. */
    alreadyPurchased = 1,
    /** The purchase request did not succeed because of a network connectivity error. */
    networkError = 3,
    /** The purchase request did not succeed. */
    notPurchased = 2,
    /** The purchase request did not succeed because of a server error returned by the Windows Store. */
    serverError = 4,
    /** The purchase request succeeded. */
    succeeded = 0,
}

StorePurchaseStatus[1]

我最终没有得到定义。如果我只有该值，我如何访问字符串名？

您在原始帖子中写的方式很好。你可以检查一下

以下是如何访问名称和值：

alert(StorePurchaseStatus[1]); // alreadyPurchased
alert(StorePurchaseStatus[StorePurchaseStatus[1]]);// 1

您使用的是什么版本的Typescript？在TypeScript2.7中，通过TypeScriptPlayed，我使用的是2.3.4
