vuedraggable自由拖拽_vue可视化拖拽编辑

最近做的项目要用到拖拽排序，我现在的项目是vue项目，所以我就屁颠屁颠的去百度有木有这样功能的插件，我就知道一定会有，那就是vuedraggable，这是一款很棒的拖拽插件，下面我来说一下怎么引入

首先在vue项目中，用npm包下载下来

npm install vuedraggable -S

下载下来后，引入插件，在你的vue文件的script标签里面这样引入

import draggable from 'vuedraggable'

别忘了下面要注册组件

components: {
    draggable
},

然后就可以在template标签里面使用了

单个组件

<draggable v-model="colors" @update="datadragEnd" :options = "{animation:500}"> <transition-group> <div v-for="element in colors" :key="element.text" class = "drag-item"> {{element.text}} </div> </transition-group> </draggable>

2个组件左右结构

<el-row :gutter="24"> <el-col :span="12"> <el-form-item label="对外产品名称"> <el-input v-model="proAttribute.description" placeholder="对外产品名称" style="width: 250px"></el-input> </el-form-item> <el-form-item label="对外产品属性"> <template> <draggable v-model="colors" @update="datadragEnd" :options = "{animation:500}"> <transition-group> <div v-for="element in colors" :key="element.text" class = "drag-item"> {{element.text}} </div> </transition-group> </draggable> </template> </el-form-item> </el-col> <el-col :span="12"> <el-form-item label="对内产品名称"> <el-input v-model="proAttribute.description" placeholder="对内产品名称" style="width: 250px"></el-input> </el-form-item> <el-form-item label="对内产品属性"> <template> <draggable v-model="colors" @update="datadragEnd" :options = "{animation:500}"> <transition-group> <div v-for="element in colors" :key="element.text" class = "drag-item"> {{element.text}} </div> </transition-group> </draggable> </template> </el-form-item> </el-col> </el-row>

下面贴一下详细用法

<template> <draggable v-model="colors" @update="datadragEnd" :options = "{animation:500}"> <transition-group> <div v-for="element in colors" :key="element.text" class = "drag-item"> {{element.text}} </div> </transition-group> </draggable> </template> <script> import draggable from 'vuedraggable' export default{ data(){ return{ msg:"这是测试组件", colors: [ { text: "Aquamarine", }, { text: "Hotpink", }, { text: "Gold", }, { text: "Crimson", }, { text: "Blueviolet", }, { text: "Lightblue", }, { text: "Cornflowerblue", }, { text: "Skyblue", }, { text: "Burlywood", } ], startArr:[], endArr:[], count:0, } }, components: { 　　draggable }, methods:{ getdata (evt) { console.log(evt.draggedContext.element.text) }, datadragEnd (evt) { evt.preventDefault(); console.log('拖动前的索引 :' + evt.oldIndex) console.log('拖动后的索引 :' + evt.newIndex) console.log(this.colors); } }, mounted () { //为了防止火狐浏览器拖拽的时候以新标签打开，此代码真实有效 document.body.ondrop = function (event) { event.preventDefault(); event.stopPropagation(); } } } </script> <style lang="scss" scoped> .test{ border:1px solid #ccc; } .drag-item{ width: 200px; height: 50px; line-height: 50px; margin: auto; position: relative; background: #ddd; margin-top:20px; } .ghostClass{ opacity: 1; } .bottom{ width: 200px; height: 50px; position: relative; background: blue; top:2px; left: 2px; transition: all .5s linear; } </style>
