vuedraggable 拖动后可以在updated中监听

vuedraggable 的拖动规则是：拖动元素后到新位置，后面元素依次退一个位置，如：

安装 vuedraggable ：

npm install vuedraggable  --save

在页面引用

import vuedraggable from 'vuedraggable';

 components: {vuedraggable},

awe-dnd 拖动后在mounted中this.$dragging.$on监听

awe-dnd拖动规则：只能直接拖动间隔一个位置的两个元素；超过一个位置，用两个中间元素作为桥梁交换位置
例如：

安装awe-dnd

npm install awe-dnd --save

在main.js 引入

import VueDND from 'awe-dnd'
Vue.use(VueDND)

细心的我提供了源码
