全局directive的写法
// 提交以后禁用按钮一段时间，防止重复提交
import Vue from 'vue';
Vue.directive('noMoreClick', {
  inserted(el, binding) {
    el.addEventListener('click', e => {
      el.classList.add('is-disabled');
      el.disabled = true;
      setTimeout(() => {
        el.disabled = false;
        el.classList.remove('is-disabled');
      }, 3000)
    })
  }
});

局部directive的写法
directives:{
      noMoreClick: {
        inserted(el, binding) {
          el.addEventListener('click', () => {
            el.classList.add('is-disabled');
            el.disabled = true;
            setTimeout(() => {
              el.disabled = false;
              el.classList.remove('is-disabled');
            }, 2000)
          })
        }
      }
    },

使用：

<el-button size="small" class="clear-btn m-t-sm m-b-sm" @click="resetForm" v-no-more-click>
  Confirm
</el-button>
