input实现手机验证码输入

实现效果：

实现思路：

1. 将code框定位到input框上
2. 通过input的输入实现验证码的输入
3. 将input输入的支赋值在code框上

小demo：

<template>
    <a-row :gutter="[12, 12]" class="m-12">
        <a-col :span="24">
            <div class="code-group">
                <div class="pc_in">
                    <div class="block">
                        <div class="g_hx">{{ codeValue?.toString().substring(0, 1) || '' }}div>
                        <div class="g_hx">{{ codeValue?.toString().substring(1, 2) || '' }}div>
                        <div class="g_hx">{{ codeValue?.toString().substring(2, 3) || '' }}div>
                        <div class="g_hx">{{ codeValue?.toString().substring(3, 4) || '' }}div>
