不显示图片/播放视频音频代码如下
代码语言：javascript复制<template>

<script>
export default {
name: "trs",
data(){
return{

}
},
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
