如何通过 outlook 插件中的 onAppointmentAttendeesChangedHandler 函数获取与会者详细信息

Question

我是 outlook 插件的新手。我已根据此链接将我的 Outlook 加载项配置为基于事件的激活https://learn.microsoft.com/en-us/office/dev/add-ins/outlook/autolaunch?tabs=xmlmanifest

当我当时从会议中删除任何人时，我没有在活动中得到他们的名字。我已经提供了代码。

launchevent.js

function onAppointmentSendHandler(event) {
  debugger;
  setSubject(event);
}
function onAppointmentAttendeesChangedHandler(event) {
  setSubject(event);
}

function onAppointmentTimeChangedHandler(event) {
  setSubject(event);
}

function setSubject(event) {
  debugger;
  console.log("event", event);

}
if (Office.context.platform === Office.PlatformType.PC || Office.context.platform == null) {
  Office.actions.associate("onAppointmentSendHandler", onAppointmentSendHandler);
  Office.actions.associate("onAppointmentAttendeesChangedHandler", onAppointmentAttendeesChangedHandler);
  Office.actions.associate("onAppointmentTimeChangedHandler", onAppointmentTimeChangedHandler);
}

现在，当我从约会中删除或添加任何收据时，我没有得到与会者的详细信息。我在调试时附上了函数的图像。 你可以在函数结果中看到我什么也没得到。

我从这里添加了与会者（你可以在图片中看到）。 所以，谁能指导我哪里做错了？

Answer 1

您可以使用

Office.context.mailbox.item.requiredAttendees.getAsync

方法调用获得实际值。

表示 RecipientsChangedEventArgs.changedRecipientFields 对象的

Office.RecipientsChangedFields

接口给出了哪些字段已更改的基本信息。在您的场景中，这是

requiredAttendees

，如果所需的与会者已更改则设置。
