Javascript 不能在移动设备上工作，但在桌面上工作，用于四个 otp 框的选项卡到下一个字段

Question

let element = $event.srcElement.nextElementSibling;
element.focus()

这里下一个元素兄弟不起作用。

如果在框 1 中输入第一个数字，然后它会自动跳到下一个框，它在桌面浏览器中工作正常，但在移动浏览器中不能正常工作？

<input type="text" #otpvalue1 maxlength="1" [value]="otpValue1" (paste)="pasteEvent($event)" (keypress)="otpBox1($event)" (keydown)="handleBackSpaceBox1($event)"/>
                        <input type="text" #otpvalue2 maxlength="1" [value]="otpValue2" (paste)="pasteEvent($event)"  (keypress)="otpBox2($event)" (keydown)="handleBackSpaceBox2($event)">
                        <input type="text" #otpvalue3 maxlength="1" [value]="otpValue3" (paste)="pasteEvent($event)"  (keypress)="otpBox3($event)" (keydown)="handleBackSpaceBox3($event)">
                        <input type="text" #otpvalue4 maxlength="1" [value]="otpValue4" (paste)="pasteEvent($event)"  (keypress)="otpBox4($event)" (keydown)="handleBackSpaceBox4($event)" />

otpBox1(obj) {
    obj = (obj) ? obj : window.event;
    let charCode = (obj.which) ? obj.which : obj.keyCode;
    if ((charCode > 31 || charCode == 13) && (charCode < 48 || charCode > 57)) {
      return false;
    }
    else {
      this.otpValue1 = obj.key;
      let otplength = this.otpValue1 + this.otpValue2 + this.otpValue3 + this.otpValue4;
      this.otplength = otplength.length;
      let element = obj.srcElement.nextElementSibling;
      if (element != null) {
        element.focus();
        obj.preventDefault();
      }
      return true;
    }
  }

需要更多代码..您如何决定是否继续前进？ 许多事件在触摸设备和那些由插入的键盘和鼠标控制的设备之间是非常不同的！
