Javascript 不适用于移动设备，但在桌面上适用于四个 otp 框的选项卡到下一个字段

Question

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

这里的下一个元素同级不起作用。

如果在框 1 中输入第一个数字，则它会自动选项卡到下一个框，它在桌面浏览器中工作正常，但在移动浏览器中无法正常工作？

<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.. 你如何决定跳到前面？ 触摸设备与由插入式键盘和鼠标控制的事件之间的许多事件都有很大不同！
