Vue實現獲取驗證碼倒計時

HTML部分：
<span v-show=“show” @click=“getCode”>獲取驗證碼

                    話不多說直接上干貨

```<span v-show="show" @click="getCode">獲取驗證碼</span>
   <span v-show="!show" class="count">{{count}} 秒</span>
JS部分：
data(){
  return {
   show: true,
   count: '',
   timer: null,
  }
 },
 methods:{
   getCode(){
     const TIME_COUNT = 60;
     if (!this.timer) {
       this.count = TIME_COUNT;
       this.show = false;
       this.timer = setInterval(() => {
       if (this.count > 0 && this.count <= TIME_COUNT) {
         this.count--;
        } else {
         this.show = true;
         clearInterval(this.timer);
         this.timer = null;
        }
       }, 1000)
      }
   } 
 }
