本文實例為大家分享了vue插件draggable實現拖拽移動圖片順序的具體方法，供大家參考，具體內容如下
例如圖片顯示的這種圖片列表、商品展示需要拖動圖片改變順序，vuedraggable可以實現拖拽。
首先，
npm i vuedraggable
然后在組件中引入，
import draggable from 'vuedraggable';
定義組件，
components: { draggable, },標簽中應用，
<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="child.picServerUrl1" alt=""> <div class="edit-pop dn"></div> <!-- <div class="edit-box dn"> <span class="banner-edit-btn" @click="eidtBanner(child.id)">編輯</span> <span class="banner-cancle-btn" @click="delateBanner(child.id)">刪除</span> </div> --> <img class="prod-choose" v-if="child.flag == 1" src="../../assets/images/not-select.png" alt="" @click="selectProd(child.decorateId)"> <img class="prod-choose" v-else-if="child.flag == 2" src="../../assets/images/prod-select.png" @click="selectProd2(child.decorateId)" alt=""> <div class="edit-box-bottom" v-if="child.property == 1"> <span class="conf-con">{{ child.goodsName }}</span> <p class="product-money"><span class="lower">低至</span>￥{{ child.lowestPrice }}</p> </div> <div class="edit-box-bottom" v-else> <span class="conf-con">{{ child.goodsName }}</span> <p class="product-money"> <img src="../../assets/images/yuedu.png" alt=""> <span class="browseNum ">{{ child.browseNum }}</span> <img src="../../assets/images/zan.png" alt=""> <span class="browseNum ">{{ child.thumbNum }}</span> </p> </div> </li> </draggable></ul>方法，
getdata (data) { }, datadragEnd (evt) { var oneId = ""; var otherId = ""; // console.log('datadragEnd方法'); console.log('拖動前的索引 :' + evt.oldIndex) console.log('拖動后的索引 :' + 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是調換結束調用的，里面可以根據需求處理一些數據。
