vue3.0 element-plus 如何清空上一次的上传文件？
<el-upload action="#" ref="upload" list-type="picture" :show-file-list="true" :limit="1" :http-request="handleUpload"> <el-button size="small" type="primary">点击上传</el-button> </el-upload>
this.$refs.upload.clearFiles() this.$refs.upload.uploadFiles.splice(this.$refs.upload.uploadFiles.length - 1, 1);
vue3.0 应该怎样写？ 已经没有this了，
