利用Vue-draggable组件, 进行Vue 项目中表格内容的拖拽排序

Vue-draggable 的github传送门 : 

https://github.com/SortableJS/Vue.Draggable

 

一. 下载依赖包:npm install vuedraggable -S  

 

二. 在需要使用的当前界面引入依赖,注册组件:

import draggable from "vuedraggable";
export default {
  components: {
    draggable,
  }

 三. 在template 中建立表格,分别写出thead 部分不变, 此处需要将draggable 渲染成tbody,不然draggable会被解析成div 影响样式。

(渲染方法:<draggable v-model="tablelist" element="tbody">

    

            <table class="dataTabble">
              <thead>
                <tr>
                  <th width="110">栏目名称</th>
                  <th width="200">发布时间</th>
                  <th width="160">公告数量</th>
                  <th width="160">操作</th>
                </tr>
              </thead>
              <draggable v-model="tablelist" element="tbody" :move="getdata" @update="datadragEnd">
                <tr v-for="(item,id) in tablelist" :key="id">
                  <td>{{item.name}}</td>
                  <td>{{item.time}}</td>
                  <td>{{item.num}}</td>
                  <td>
                    <div class="tabopa">
                      <a @click="dialogFormVisible = true" style="cursor:pointer">添加</a>
                      <a @click="open2">删除</a>
                    </div>
                  </td>
                </tr>
              </draggable>
            </table>
            <div class="zhu mt40">提示:拖动可对栏目进行排序</div>

此处data部分,通过{ {   } } 获取data中数据,实际中通过请求获取

  data() {
    return {
      tablelist: [
        { id: 1, name: "活动消息1", time: "2018-08-25 14:54", num: "1000" },
        { id: 2, name: "公司消息2", time: "2018-08-25 14:54", num: "200" },
        { id: 3, name: "个人消息3", time: "2018-08-25 14:54", num: "30000" },
        { id: 4, name: "客户消息4", time: "2018-08-25 14:54", num: "40" }
      ],
    };
  },

 四.相关方法

获取拖动中和拖动结束时的id

methods: {
    //拖动中与拖动结束
    getdata(evt) {
      console.log(evt.draggedContext.element.id);
    },
    datadragEnd(evt) {
      console.log("拖动前的索引 :" + evt.oldIndex);
      console.log("拖动后的索引 :" + evt.newIndex);
      console.log(this.tags);
    },

 五.贴出全部代码

<template>
  <div>
    <!--main-->
            <table class="dataTabble">
              <thead>
                <tr>
                  <th width="110">栏目名称</th>
                  <th width="200">发布时间</th>
                  <th width="160">公告数量</th>
                  <th width="160">操作</th>
                </tr>
              </thead>
              <draggable v-model="tablelist" element="tbody" :move="getdata" @update="datadragEnd">
                <tr v-for="(item,id) in tablelist" :key="id">
                  <td>{{item.name}}</td>
                  <td>{{item.time}}</td>
                  <td>{{item.num}}</td>
                  <td>
                    <div class="tabopa">
                      <a @click="dialogFormVisible = true" style="cursor:pointer">添加</a>
                      <a @click="open2">删除</a>
                    </div>
                  </td>
                </tr>
              </draggable>
            </table>
            <div class="zhu mt40">提示:拖动可对栏目进行排序</div>
    <!--main end-->
  </div>
</template>
<script>
import draggable from "vuedraggable";
export default {
  components: {
    draggable,
  },
  data() {
    return {
      tablelist: [
        { id: 1, name: "活动消息1", time: "2018-08-25 14:54", num: "1000" },
        { id: 2, name: "公司消息2", time: "2018-08-25 14:54", num: "200" },
        { id: 3, name: "个人消息3", time: "2018-08-25 14:54", num: "30000" },
        { id: 4, name: "客户消息4", time: "2018-08-25 14:54", num: "40" }
      ],
    };
  },
  methods: {
    //拖动中与拖动结束
    getdata(evt) {
      console.log(evt.draggedContext.element.id);
    },
    datadragEnd(evt) {
      console.log("拖动前的索引 :" + evt.oldIndex);
      console.log("拖动后的索引 :" + evt.newIndex);
      console.log(this.tags);
    },
  }
}
</script>
<style>
</style>
