效果

若使用 请自行优化代码和样式

不显示图片/播放视频音频代码如下

<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)">删除</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; 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() { let vm = this; window.addEventListener("dragdrop", this.testfunc, false); document.addEventListener("dragover",function () { console.log(111) vm.dt = "拖动到此处上传文件" 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 = "拖动到此处上传文件" }, 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 = "上传完成，可继续上传" } } }</script><style scoped></style>

如果想要显示图片/播放视频/播放音频

这里我默认显示/播放最后一个上传文件 根据需求修改即可

<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)">删除</button> </div> <div style="position:relative;top: 100px"> <img v-if="isImage" :src="srcs" style="width: 800px" /> <video v-if="isVideo" controls :src="srcs" style="width: 800px"></video> <audio v-if="isAudio" controls :src="srcs" style="width: 800px"></audio> </div> </div></template><script>export default { name: "trs", data() { return { dt: "", fileList: [], srcs:"", isImage:false, isAudio:false, isVideo:false }; }, filters: { sizeType(val) { let kbs = val / 1024; let mbs = 0; let gbs = 0; 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() { let vm = this; window.addEventListener("dragdrop", this.testfunc, false); document.addEventListener("dragover", function() { console.log(111); vm.dt = "拖动到此处上传文件"; console.log(vm.dt); }); }, methods: { readFile(file){ let vm = this; let reader = new FileReader(); reader.readAsDataURL(file) reader.onload = function () { let type = file.type.substr(0,5); if(type=="image"){ vm.isImage = true; vm.isAudio =false; vm.isVideo = false; }else if(type=="audio"){ vm.isImage = false; vm.isAudio =true; vm.isVideo = false; }else if(type=="video"){ vm.isImage = false; vm.isAudio = false; vm.isVideo = true; }else { alert("不是图片/视频/音频") } vm.srcs = reader.result; // this.$nextTick(()=>{ // // }) } }, 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 = "拖动到此处上传文件"; }, ttrs(e) { console.log(e); console.log(e.dataTransfer.files); let datas = e.dataTransfer.files; datas.forEach(item => { this.fileList.push(item); }); this.readFile(this.fileList[this.fileList.length-1]) e.stopPropagation(); e.preventDefault(); this.dt = "上传完成，可继续上传"; } }};</script><style scoped></style>
