element ui el-upload on-progress 事件不能触发，可以改用 on-change
handleChange(file, fileList) { this.fileList = fileList // 显示进度条 if (file.status === 'ready') { this.loadProgress = 0 this.progressFlag = true let timer = setInterval(() => { if (this.loadProgress >= 99) { clearInterval(timer) timer = null return } this.loadProgress += 1 }, 20) } },
在上传成功的方法里面 this.progressFlag = false
