本文实例为大家分享了vue实现div拖拽互换位置的具体代码，供大家参考，具体内容如下

template模板

<transition-group tag="div" class="container"> <div class="item" v-for="(item,index) in items" :key="item.key" :style="{background:item.color,width:'80px',height:'80px'}" draggable="true" @dragstart="handleDragStart($event, item)" @dragover.prevent="handleDragOver($event, item)" @dragenter="handleDragEnter($event, item)" @dragend="handleDragEnd($event, item)" > </div></transition-group>

script：

<script>export default { name: 'Toolbar', data () { return { items: [ { key: 1, color: '#ffebcc'}, { key: 2, color: '#ffb86c'}, { key: 3, color: '#f01b2d'} ], dragging: null } }, methods:{ handleDragStart(e,item){ this.dragging = item; }, handleDragEnd(e,item){ this.dragging = null }, //首先把div变成可以放置的元素，即重写dragenter/dragover handleDragOver(e) { e.dataTransfer.dropEffect = 'move'// e.dataTransfer.dropEffect="move";//在dragenter中针对放置目标来设置! }, handleDragEnter(e,item){ e.dataTransfer.effectAllowed = "move"//为需要移动的元素设置dragstart事件 if(item === this.dragging){ return } const newItems = [...this.items] console.log(newItems) const src = newItems.indexOf(this.dragging) const dst = newItems.indexOf(item) newItems.splice(dst, 0, ...newItems.splice(src, 1)) this.items = newItems } }}</script> <style scoped> .container{ width: 80px; height: 300px; position: absolute; left: 0; display:flex; flex-direction: column; padding: 0; } .item { margin-top: 10px; transition: all linear .3s }
