I wrote an alert prompt box myself. Because the system alert is in WeChat on the Apple mobile phone, when prompted, the website address will be displayed at the top.
At the same time, other subsequent operations need to be filled in in js. So I simply wrote an alert prompt box using div and closed it automatically.
