Vue implements multi-grid input box on mobile terminal

Recently, the company has put forward a requirement to complete the h5 page operation as shown in the figure below.

There weren't many wheels available online, so I made one myself. Without further ado, let's get straight to the code.

<div class="verify-tel">
    <h1>SMS Verification</h1>
    <h2>SMS Verification</h2>
    <div>
        <input ref="pwd" :maxlength="digits.length" v-model="msg" style="position: absolute;z-index: -1;opacity: 0"/>
        <ul class="pwd-wrap" @click="focus">
            <li v-for="(item,key) in digits" :style="{'margin-right': (100-10*digits.length)/(digits.length-1)+'%','width':'10%'}" >
                <span v-if="msgLength > key">{{msg.substring(key,key+1)}}</span>
            </li>
        </ul>
    </div> 
</div>

CSS part (the style content is too complicated, please skip the modification)

html,body{
    width: 100%;
    height: 100%;
    background: #fbf9fe;
  }
  .verify-tel{
    background-color: #f9f9f9;

js part of the code

<script>
  export default{
    data(){
      return {
        page:0, //1 is for SMS verification digits:['','','','','',''], //Input box digit control, how many "input boxes" can be configured here
        msg:'',
        msgLength:0,
      }
    },
    methods:{
      //Mobile phone number verification interface function verifyTels:async function () {
        try{
        }catch(e){
          console.log(e)
        }
      },
      //Make the input box focus focus(){
        this.$refs.pwd.focus(); 
      },
    },
    beforeMount:function () {
        //Because my business needs require multiple pages, and digits are transmitted from the parent component, I hide it and only one line of code remains.
        this.page=1;
    },
    watch:
      msg(curVal){
        //Monitor the input length. If the input is complete, automatically call the verification interface function if(curVal.trim().length===this.digits.length){
           this.verifyTels(); 
        }
        this.msgLength = curVal.length;
      },
      'page':{
        handler:function (newValue, oldValue) {
          if(oldValue==0&&newValue==1){
            //When entering the page for the first time, the focus is automatically obtained. This can be optimized.
            this.timer = setTimeout(()=>{this.$refs.pwd.focus()},500);
          }
        },
        deep:true
      }
    },
    beforeDestroy:function () {
      clearTimeout(this.timer);
    }
