vue插件draggable实现拖拽移动图片顺序

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。
