Vue中实现拖放排序，啥也不说，贴上代码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<style>
ul {
min-height: 100px;
width: 200px;
margin: 20px auto;
background: #eee;
}
li {
min-height: 2em;
margin-top: 10px;
background: #abcded;
}
/ 组件过渡类 /
.drog-move {
transition: transform 1s;
}
</style>
<body>
<div id="app">
<transition-group name="drog" tag="ul">
<li draggable="true" v-for="(item, index) in lists" @dragstart="dragStart($event, index)" @dragover="allowDrop" @drop="drop($event, index)" v-bind:key="item">{{item}}</li>
</transition-group>
</div>
</body>
<script src="/UploadFiles/2021-04-02/vue.min.js">
ps：下面看下vue 拖拽排序的实例代码，具体代码如下所示：
<template>
<section class="main">
<div class="drag-box-left">
<div class="drag-title">拖动排序</div>
<div class="drag-list" draggable="true"
v-for="list in data1"
:data-id="list.id"
@dragstart="dragstartEvent"
@dragend="dragendEvent"
@dragenter="dragenterEvent"
@dragleave="dragleaveEvent"
@dragover="dragoverEvent"
>{{list.title}}</div>
</div>
</section>
</template>
<script>
export default {
data() {
return {
dragElement: null,
lock: true,
data1: [
{id: 1, title: '这里是列表1的标题'},
{id: 2, title: '这里是列表2的标题'},
{id: 3, title: '这里是列表3的标题'},
{id: 4, title: '这里是列表4的标题'},
{id: 5, title: '这里是列表5的标题'},
{id: 6, title: '这里是列表6的标题'},
{id: 7, title: '这里是列表7的标题'}
],
data2: [
{id: 1, title: '这里是列表11的标题'},
{id: 2, title: '这里是列表12的标题'},
{id: 3, title: '这里是列表13的标题'},
{id: 4, title: '这里是列表14的标题'}
]
}
},
methods: {
dragstartEvent(ev) {
const self = this;
self.dragElement = ev.target;
ev.target.style.backgroundColor = '#f8f8f8';
},
dragendEvent(ev) {
ev.target.style.backgroundColor = '#fff';
ev.preventDefault();
},
dragenterEvent(ev) {
const self = this;
if(self.dragElement != ev.target){
ev.target.parentNode.insertBefore(self.dragElement, ev.target);
}
},
dragleaveEvent(ev) {
const self = this;
if(self.dragElement != ev.target){
if(self.lock && (ev.target == ev.target.parentNode.lastElementChild || ev.target == ev.target.parentNode.lastChild)){
ev.target.parentNode.appendChild(self.dragElement);
self.lock = false;
}else{
self.lock = true;
}
}
},
dragoverEvent(ev) {
ev.preventDefault();
}
}
}
</script>
<style scoped>
.drag-box-left{
float: left;
width: 45%;
}
.drag-box-right{
float: right;
width: 45%;
}
.drag-list{
border: 1px solid #ddd;
padding:10px;
margin-bottom: 20px;
transition: border .3s;
}
.drag-list:hover{
border: 1px solid #20a0ff;
}
.drag-title{
font-weight: 400;
line-height: 25px;
margin: 10px 0;
font-size: 22px;
color: #1f2f3d;
}
</style>
