## zh-CN

使用 `fileList` 对列表进行完全控制，可以实现各种自定义功能，以下演示二种情况：
|
|||
|
|
|
|||
|
|
1. 上传列表数量的限制。
|
|||
|
|
|
|||
|
|
2. 读取远程路径并显示链接。
|
|||
|
|
|

## en-US

|||
|
|
You can gain full control over filelist by configuring `fileList`. You can accomplish all kinds of customed functions. The following shows two circumstances:
|
|||
|
|
|
|||
|
|
1. limit the number of uploaded files.
|
|||
|
|
|
|||
|
|
2. read from response and show file link.
