Question

抱歉，功能链不完全是这样，但是我有这段代码

ActivityService._hubConnection.on('Send', (activity: ActivityDto) => {
   this.activity = activity;
   if (activity.title === 'LOGIN') {
      this.showActivity(`${activity.user.firstName} ${activity.user.surname} logged in.`);
   } else if (activity.title === 'COMMENT') {
      this.showActivity(`${activity.user.firstName} ${activity.user.surname} commented on: XB-ID-${activity.messageId}`, `/app/main/dashboard/xpert-detail/${activity.messageId}/comment`, null);
   } else if (activity.title === 'ASSIGNED') {
      this.showActivity(`${activity.user.firstName} ${activity.user.surname} assigned: XB-ID-${activity.messageId}`, `/app/main/dashboard/xpert-detail/${activity.messageId}/comment`);
   } else if (activity.title === 'SYNC COMPLETE') {
      this.showActivity(`Sync complete, View Changes`, `/app/main/dashboard/alerts/all`, 'complete');
   } else if (activity.title === 'FILE') {
      this.showActivity(`${activity.user.firstName} ${activity.user.surname} filed: XB-ID-${activity.messageId}`, `/app/main/dashboard/xpert-detail/${activity.messageId}/comment`)
   } else if (activity.title === 'XPERT SYNC') {
      this.showActivity(`Sync In Progress.`, `/app/main/dashboard/activity`, 'start' );
   }
});

 showActivity(popText, notifLink = null, sync = null) {
    this.popupText = popText;
    if (notifLink !== null) {
        this.notifLink = notifLink;
    }
    if (sync !== null) {
        if (sync === 'complete') {
            this._activityService.finishSync();
        } else if (sync === 'start') {
            this._activityService.startSync();
        }
    }
    this.showNotif();
}

showNotif() {
    const notif = <HTMLElement>document.querySelector('.notification-tab');
    notif.style.display = 'flex';
    notif.style.bottom = '0';
    setTimeout(() => {
        notif.style.bottom = '-50px';
        setTimeout(() => {
            notif.style.display = 'none';
        }, 500);
    }, 5000);
}

现在我无法弄清楚为什么它不起作用，基本上发生的是说正在接收评论，所以activity.title ==='COMMENT'，它应该运行showActivity()函数，然后应该运行运行showNotif()函数，将断点放在函数的每个部分上，然后断点命中this.showActivity（），但是什么也没发生？没有其他断点被击中，我无法弄清楚问题出在哪里！对我来说没有任何意义。

任何帮助将不胜感激，我不知道可能出什么问题了...

谢谢

尝试将您的函数包装起来以尝试.. catch，也许存在uncatch异常。

  showActivity(popText, notifLink = null, sync = null) {
   try  {
    this.popupText = popText;
    if (notifLink !== null) {
      this.notifLink = notifLink;
    }
    if (sync !== null) {
      if (sync === 'complete') {
        this._activityService.finishSync();
      } else if (sync === 'start') {
        this._activityService.startSync();
      }
    }
    this.showNotif();
   } catch (e) {
    console.error(e);
   }
}

也包裹在这里）

if (activity.title === 'COMMENT') {
  try {
    this.showActivity(`${activity.user.firstName} ${activity.user.surname} commented on: XB-ID-${activity.messageId}`, `/app/main/dashboard/xpert-detail/${activity.messageId}/comment`, null);
  } catch (e) {
    console.error(e);
  }
}
