vue2 拖动排序 vuedraggable组件的实现

一、安装插件

npm install -D vuedraggable

二、在需要排序的界面中引入组件

<script>
import draggable from 'vuedraggable'
export default {
name: 'HelloWorld',
components: {
 draggable
},

三、在模板中使用

<draggable v-model="groups" @chang="change" @start="start" @end="end" :move="move">
 <div v-for="(item, index) in groups" :key=index>
  item {{item}}
 </div>
</draggable>

四、实现change、start、end、move方法，v-model绑定的数据就是排序后的数据，可以传递给后台修改数据库数据

methods: {
 change (event) {
  console.log('change', event)
 },
 start (event) {
  console.log('start', event)
 },
 end (event) {
  console.log('end', event, this.groups)
 },
 move (event, orgin) {
  console.log('move', event, orgin)
 }
}

五、完整代码，参考网址

<template>
<div>
 排序
 <draggable v-model="groups" @chang="change" @start="start" @end="end" :move="move">
  <!-- <transition-group> -->
   <div v-for="(item, index) in groups" :key=index>
    item {{item}}
   </div>
  <!-- </transition-group> -->
 </draggable>
</div>
</template>
<script>
import draggable from 'vuedraggable'
export default {
name: 'HelloWorld',
components: {
 draggable
},
data () {
 return {
  groups: [
   1, 2, 3, 4, 5
  ]
 }
},
methods: {
 change (event) {
  console.log('change', event)
 },
 start (event) {
  console.log('start', event)
 },
 end (event) {
  console.log('end', event, this.groups)
 },
 move (event, orgin) {
  console.log('move', event, orgin)
 }
}
}
</script>
