本文实例为大家分享了vue插件draggable实现拖拽移动图片顺序的具体方法,供大家参考,具体内容如下
例如图片显示的这种图片列表、商品展示需要拖动图片改变顺序,vuedraggable可以实现拖拽。
首先,
npm i vuedraggable
然后在组件中引入,
import draggable from 'vuedraggable';
定义组件,
components: { draggable, },
标签中应用,
<ul class="pic-list clearfix"> <draggable class="list-group" v-model="hotVOList" :options="{animation: 60,}" :move="getdata" @update="datadragEnd"> <li v-for="(child,index) in hotVOList" :key="index"> <img :src="/UploadFiles/2021-04-02/child.picServerUrl1">方法,
getdata (data) { }, datadragEnd (evt) { var oneId = ""; var otherId = ""; // console.log('datadragEnd方法'); console.log('拖动前的索引 :' + evt.oldIndex) console.log('拖动后的索引 :' + evt.newIndex) if(evt.newIndex == this.hotVOList.length - 1 && this.pageData.pageNum < Math.ceil(this.pageData.total/10)){ this.$api.get("/mallConfig/hot_goods_list/" + this.addHotMallID,{ pageNum:this.pageData.pageNum+1, pageSize:this.pageData.pageSize }, su => { if (su.httpCode == 200) { this.newHotVOList = su.data.hotVOList; oneId = su.data.hotVOList[0].decorateId; otherId = this.hotVOList[evt.newIndex].decorateId; this.$api.get( "/mallConfig/hot_product/exchage_turn/" + this.addHotMallID, { oneId: oneId, otherId :otherId, }, su => { if (su.httpCode == 200) { this.getBodyList(this.addHotMallID); } }, err => {}, { accessToken: sessionStorage.getItem("accessToken") } ); } }, err => {}, { accessToken: sessionStorage.getItem("accessToken") }) } else if(evt.newIndex == this.hotVOList.length - 1 && this.pageData.pageNum == Math.ceil(this.pageData.total/10)){ otherId = this.hotVOList[evt.newIndex].decorateId; oneId = -1; this.$api.get( "/mallConfig/hot_product/exchage_turn/" + this.addHotMallID, { oneId: oneId, otherId :otherId, }, su => { if (su.httpCode == 200) { this.getBodyList(this.addHotMallID); } }, err => {}, { accessToken: sessionStorage.getItem("accessToken") } ); } else { otherId = this.hotVOList[evt.newIndex].decorateId; oneId = this.hotVOList[evt.newIndex + 1].decorateId; this.$api.get( "/mallConfig/hot_product/exchage_turn/" + this.addHotMallID, { oneId: oneId, otherId :otherId, }, su => { if (su.httpCode == 200) { this.getBodyList(this.addHotMallID); } }, err => {}, { accessToken: sessionStorage.getItem("accessToken") } ); } },datadragEnd是调换结束调用的,里面可以根据需求处理一些数据。
