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>总结
