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="child.picServerUrl1" alt="">
      <div class="edit-pop dn"></div>
      <!-- <div class="edit-box dn">
      <span class="banner-edit-btn" @click="eidtBanner(child.id)">编辑</span>
      <span class="banner-cancle-btn" @click="delateBanner(child.id)">删除</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。
