el-upload组件可以上传多张图片,只需要设置multiple属性为true即可。同时,也需要在后端接收多个文件的处理。以下是一个示例:
```
<el-upload
multiple
action="/upload"
:on-success="handleSuccess">
<el-button>上传图片</el-button>
</el-upload>
```
在后端处理多个文件的示例(使用Node.js和Express):
```
const express = require('express');
const multer = require('multer');
const app = express();
const upload = multer({ dest: 'uploads/' });
app.post('/upload', upload.array('files'), (req, res) => {
console.log(req.files);
// do something with the uploaded files
res.send('Files uploaded successfully');
});
app.listen(3000, () => {
console.log('Server started on port 3000');
});
```
以上示例中,multer库用于处理上传的文件,upload.array('files')指定了接收的文件字段名为files,req.files即为上传的文件数组。在实际开发中,应该根据具体需求进行更详细的配置和处理。
