JS html css IOS 苹果手机吊起键盘，页面会被推上去

if (navigator.userAgent.toLocaleLowerCase().includes('iphone')) {
      // @ts-ignore
      this.intervalFlag = setInterval(() => {
        document.querySelector('body').scrollTop = 0;
      }, 200);
    }

强制设置body scrollTop ＝ 0

 setTimeout(() => {
      if (navigator.userAgent.toLowerCase().includes('iphone')) {
        document.querySelector('app-confirm-loan').addEventListener('touchmove', (e) => {
          e.preventDefault();
        });
      }
    }, 100);
