Office.SeriesTime TypeScript 定义缺少属性只有方法

Question

Office.context.mailbox.item.recurrence.getAsync() 返回一个对象，但我无法将其部分转换为其他变量。 例如接口 Office.SeriesTime 只定义了 GetXXX() 方法

/**
 * Gets the duration in minutes of a usual instance in a recurring appointment series.
 * 
 * [Api set: Mailbox 1.7]
 *
 * @remarks
 * 
 * **{@link https://docs.microsoft.com/office/dev/add-ins/outlook/understanding-outlook-add-in-permissions | Minimum permission level}**: `ReadItem`
 * 
 * **{@link https://docs.microsoft.com/office/dev/add-ins/outlook/outlook-add-ins-overview#extension-points | Applicable Outlook mode}**: Compose or Read
 */
getDuration(): number;

例如这不会编译，因为接口 Office.SeriesTime 没有定义属性。

    const fixedRecurrence: Office.SeriesTime = recurrence.seriesTime;
    if (fixedRecurrence.endYear === 0) {
      fixedRecurrence.endYear = fixedEndDate.getFullYear();
      fixedRecurrence.endMonth = fixedEndDate.getMonth() + 1;
      fixedRecurrence.endDay = fixedEndDate.getDate();
    }

Answer 1

查看Office.SeriesTime interface 成员。看来您需要改用getEndDate() 方法，它允许以以下ISO 8601 日期格式获取重复模式的结束日期："YYYY-MM-DD"。

// This example gets the end date of a recurring appointment series.
Office.context.mailbox.item.recurrence.getAsync(callback);

function callback(asyncResult) {
    var context = asyncResult.context;
    var recurrence = asyncResult.value;
    var endDate = recurrence.seriesTime.getEndDate();
}
