vue封装短信验证码，刷新缓存倒计时

HTML代码

          <a-form-item field="verifyCode" label="验证码:">
            <a-input v-model="formData.verifyCode" placeholder="短信验证码" class="login-form-button" allow-clear>
              <template #append>
                <span
                  :class="{ 'login-form-send': true, 'login-form-send-disabed': typeof theTime == 'number' }"
                  @click="sendVerificationCode"
                  >{{ theTime }}{{ theTime != '发送验证码' ? 's' : '' }}span
                >
              template>
            a-input>
          a-form-item>

ts部分
