如何在el-upload上传完成的时候,去掉列表呢?
方法
利用 this.$refs.upload.clearFiles();去掉文件列表
template中代码
<el-upload
ref="upload"
class="upload-demo"
:action="actionFile"
:headers="headersFile"
:on-success="onSuccessFile"
:on-error="onErrorFile"
:before-upload="beforeFileUpload"
:on-progress="onProgressFile"
name="file"
>
<el-button
size="mini"
icon="el-icon-folder-add"
plain
type="primary"
>上传</el-button
>
</el-upload>
methods中代码
onErrorFile(){
this.$message("导入失败!");
this.$refs.upload.clearFiles(); //去掉文件列表
},
onSuccessFile(response) {
// 你的代码
this.$message("导入成功!");
this.$refs.upload.clearFiles(); //去掉文件列表
},
