vue实现实时上传文件进度条
本文实例为大家分享了vue实时上传文件进度条,供大家参考,具体内容如下
//上传文件组件 <el-upload action :show-file-list="false" :before-upload="uploadFile" > <el-button type="primary" :disabled="progressFlag">上传数据</el-button> </el-upload> //进度条组件 <div :class="progressFlag?'progress':'progress1'"> <el-progress id="progress" type="circle" :percentage="percent" :stroke-width="8" :width="100" :show-text="true" stroke-linecap="round" :format="progressFormat" ></el-progress> </div>
data() { return { percent:0, progressFlag:false, deg:135, status:this.percent<100?"":"success",//进度条组件加上状态后不显示文字 color:[ {color:"#fdfdfd",percentage:99}, {color:"#ccccc",percentage:100}, ] } }
methods:{ async uploadFile(file){ //:on-progress="uploadFile"上传时会多次调用,由于是本地,间隔较大 let reg = /(?<=\.)[a-z]+$/g let fileType = file.name.match(reg)+"" let typeArr = ["xls","xlsx","csv"] if(!typeArr.includes(fileType)){ this.$message.warning("上传文件格式错误!") return } let formData = new FormData() formData.append('file',file) // realtimeUploadLocal({ // file:formData, // uid:this.$store.state.userInfo.user.uid, // }) this.progressFlag = true await realtimeUpload(formData,this).then((res)=>{ if(res.code == "0"){ this.$message.success(res.data) }else{ this.$message.warning(res.data) } }) setTimeout(()=>{ this.progressFlag = false // this.rotateFn(0) this.percent = 0 },1000) }, progressFormat(percentage){ return percentage<100?"已上传("+percentage+"%)":"上传完成" } }
<style scoped lang="less"> .progress1{ display:none;} .progress{ display: flex; width: 80px; height: 80px; position: absolute; top: 40px; left: 50%; transform: translate(-50%, 0); background-color: transparent; } </style>
