在做项目过程中，需求是点击孔位单击弹出对话框查看产品总数，双击弹出对话框查看详情。一开始直接click和dblclick写在标签里面，但是不管怎么样，总是执行单击事件

解决办法：利用计时器，在大概时间模拟双击事件

html部分代码：

 <div class="grid-content">
    <el-button 
　　　　v-for="(item,index) in items" :key="index" 
　　 @click="storageCount(item.id)" 
　　 @dblclick.native="storageDetail(item.id)" 
　　　 class="inline-cell" 
　　 :class="colors[item.status]">
           {{item.id}}</el-button>
 </div>

.native主要用于监听组件根元素的原生事件,主要是给自定义的组件添加原生事件。

官方对.native修饰符的解释为：有时候，你可能想在某个组件的根元素上监听一个原生事件。可以使用 v-on 的修饰符 .native js部分代码

<script>
import desDialog from './dialog';
import detailDialog from './detailDialog';
var time = null;  //  在这里定义time 为null 
export default {
  name: 'storeTable',
  components: {
    desDialog,
    detailDialog
  },
  props: ['providerid'],
  data() {
    return {
      colors: ['space', 'isBuy'],
      showDialog: false,
      showDialogT: false
    };
  },
  methods: {
　　// 单击事件函数
    storageCount(id) {
      clearTimeout(time);  //首先清除计时器
      time = setTimeout(() => {
        this.showDialog = !this.showDialog;  
        const obj = {};
        obj.cutname = id;
        obj.providerid = this.providerid;
        this.$store.dispatch('GetStorageCount', obj);
      }, 300);   //大概时间300ms
    },
　　// 双击事件函数，清除计时器，直接处理逻辑
    storageDetail(id) {
      clearTimeout(time);  //清除
      this.showDialogT = !this.showDialogT;
      const obj = {};
      obj.cutname = id;
      obj.providerid = this.providerid;
      this.$store.dispatch('GetStorageDetail', obj);
    },
    close() {
      this.showDialog = false;
    },
    closeT() {
      this.showDialogT = false;
    }
  }

双击确认事件@cell-dblclick 也可以写成@row-dblclick
