大家好，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
<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>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
