点击后的不可点击状态

2、代码实现

<template>
 <div class="my-code">
   <input class="my-code-input" type="text" v-model="login_form.captcha" placeholder="Your Captcha">
   <div class="my-code-get" @click="get_captcha" id="new_yan">
     <span v-show="show">Get Captcha</span>
     <span v-show="!show">{{ count }} s</span>
   </div>
 </div>
</template>

<script>
  import store from '@/store'
  import Vue from 'vue'
  import $ from 'jquery'

  export default {
    name: "register",
    data () {
      return {
        show: true,
        count: 60,
        timer: null,
      }
    },
    methods: {
      get_captcha() {
         if (this.login_form.username === '' ) {
          alert('Phone number or mailbox cannot be empty')
        } else {
          if(this.timer == null){
            getValidate(this.login_form.username).then(response => {
              const data = response.data
              console.log(data)
              console.log('成功')
            }).catch(error => {
              console.log(error)
              alert(error)
            })
          } 
          if (!this.timer) {
            this.count = 60;
            this.show = false;
            $(".my-code-get").addClass("huise")
            // 将鼠标设置为不可点击状态
            document.getElementById('new_yan').style.cursor = 'not-allowed'
            this.timer = setInterval(() => {
              if (this.count > 0 && this.count <= 60) {
