taskpane.js

Office.onReady((info) => {
  if (info.host === Office.HostType.Outlook) {
    document.getElementById("sideload-msg").style.display = "none";
    document.getElementById("app-body").style.display = "flex";
    document.getElementById("run").onclick = run;

    // Add the following code to register the event handler for ItemSend event
    Office.context.mailbox.addHandlerAsync(
      Office.EventType.ItemSend,
      onItemSend
    );
  }
});

export async function run() {
  /**
   * Insert your Outlook code here
   */
}

// Add the following function to handle the ItemSend event
async function onItemSend(event) {
  // Prevent sending the email if certain condition is not met
  console.log("ItemSend event triggered.");
  event.preventDefault();
}

onItemSend 函数在按下 Send 按钮后从 Outlook 撰写新电子邮件时不起作用，我尝试向该函数添加 API 请求但它不起作用，我的代码似乎有什么问题
