如何使用officejs在功能区命令中显示任务窗格选定数据

<script src="https://appsforoffice.microsoft.com/lib/1/hosted/office.js"></script>

Office.initialize = function () {
  // 注册命令按钮点击事件处理程序
  Office.context.ui.addHandlerAsync(
    Office.EventType.ItemChanged,
    onItemChanged,
    function (result) {
      if (result.status === Office.AsyncResultStatus.Failed) {
        console.error(result.error.message);
      }
    }
  );
};

function onItemChanged(eventArgs) {
  if (eventArgs.type === Office.MailboxEnums.ItemChangeType.Read) {
    // 获取选定数据
    Office.context.mailbox.item.getSelectedDataAsync(
      Office.CoercionType.Text,
      function (result) {
        if (result.status === Office.AsyncResultStatus.Succeeded) {
          var selectedData = result.value;

          // 显示任务窗格
          Office.context.ui.displayDialogAsync(
            'https://your-task-pane-url',
            { width: 30, height: 30, displayInIframe: true },
            function (result) {
              if (result.status === Office.AsyncResultStatus.Succeeded) {
                var dialog = result.value;
                dialog.addEventHandler(
                  Office.EventType.DialogMessageReceived,
                  function (args) {
                    // 处理任务窗格发送的消息
                    var message = args.message;
                    // ...
                  }
                );
              } else {
                console.error(result.error.message);
              }
            }
          );
        } else {
          console.error(result.error.message);
        }
