效果

若使用 請自行優化程式碼和樣式

不顯示圖片/播放視訊音訊程式碼如下

<template>
 <div>
  <div v-on:dragover="tts" v-on:drop="ttrs" style="width: 800px;height: 200px;border: 1px solid black;font-size: 40px;line-height: 200px">
   {{dt}}
  </div>
  <div v-for="(item,index) in fileList" :key="index" style="width: 800px;height: 200px;border: 1px solid black;font-size: 40px;position: relative;top:10px">
   <p style="font-size: 20px;float: left;position: relative;left: 20pxword-wrap:break-word;word-break:normal;">{{item.name}}</p>
   <h5 style="float:right;position: absolute;top: 80px;right: 20px">{{item.type}}</h5>
   <h6 style="position: absolute;top: 80px;float: left;left: 20px">{{item.size | sizeType}}</h6>
   <button style="float: right" @click="del(index)">刪除</button>
  </div>
 </div>
</template>

<script>
 export default {
  name: "trs",data(){
   return{
    dt:"",fileList:[]
   }
  },filters:{
   sizeType(val){
    let kbs = val/1024;
    let mbs = 0;
    let gbs = 0;
 
程式設計客棧
    if(kbs>=1024){
     mbs = kbs/1024;
    }
    if(mbs>=1024){
     gbs=mbs/1024
     return gbs.toFixed(2)+"GB";
    }else if (mbs>=1){
     return mbs.toFixed(2)+"MB"
    }else {
     return kbs.toFixed(2)+"KB"
    }
   }
  },mounted() {
   http://www.cppcns.comlet vm = this;
   window.addEventListener("dragdrop",this.testfunc,false);


   document.addEventListener("dragover",function () {
    console.log(111)
    vm.dt = "拖動到此處上傳檔案"
    console.log(vm.dt)
   })
  },methods:{
   testfunc(event) {
    alert("dragdrop!");
    event.stopPropagation();
    event.preventDefault();
   },del(index){
    this.fileList.splice(index,1)
    if(this.fileList.length==0){
     this.dt = ""
    }
   },tts(e){
    console.log(e)
    this.dt = "拖動到此處上傳檔案"
   },ttrs(e){
    console.log(e)
    console.log(e.dataTransfer.files)
    let datas = e.dataTransfer.files;
    datas.forEach(item=>{
     this.fileList.push(item)
    })
    e.stopPropagation();
    e.preventDefault();
    this.dt = "上傳完成，可繼續上傳"

   }
  }
 }
</script>

<style scoped>

</style>

如果想要顯示圖片/播放視訊/播放音訊

這裡我預設顯示/播放最後一個上傳檔案 根據需求修改即可

<template>
 <div>
 <div
  v-on:dragover="tts"
  v-on:drop="ttrs"
  style="width: 800px;height: 200px;border: 1px solid black;font-size: 40px;line-height: 200px"

  {{ dt }}
 </div>
 <div
  v-for="(item,index) in fileList"
  :key="index"
  style="width: 800px;height: 200px;border: 1px solid black;font-size: 40px;position: relative;top:10px"
 >
  <p
  style="font-size: 20px;float: left;position: relative;left: 20pxword-wrap:break-word;word-break:normal;"
  >
  {{ item.name }}
  </p>
  <h5 style="float:right;position: absolute;top: 80px;right: 20px">
  {{ item.type }}
  </h5>
  <h6 style="position: absolute;top: 80px;float: left;left: 20px">
  {{ item.size | sizeType }}
  </h6>
  <button style="float: right" @click="del(index)">刪除</button>

  mbs = kbs / 1024;
  }
  if (mbs >= 1024) {
  gbs = mbs / 1024;
  return gbs.toFixed(2) + "GB";
  } else if (mbs >= 1) {

    }
    vm.srcs = reader.result;
    // this.$nextTick(()=>{

   }
  },testfunc(event) {

  event.stopPropagation();

  this.fileList.splice(index,1);
  if (this.fileList.length === 0) {
