+## 关闭预览点击文件替换
+
+上传组件可通过设置 `use-preview` 来关闭文件预览并启用点击文件替换。
+
+```html
+<wd-upload
+  :file-list="fileList"
+  :use-preview="false"
+  action="https://mockapi.eolink.com/zhTuw2P8c29bc981a741931bdd86eb04dc1e8fd64865cb5/upload"
+  @change="handleChange"
+></wd-upload>
+```
+
 ## 拦截预览图片操作
 
 设置 `before-preview` 函数，在用户点击图片进行预览时，会执行 `before-preview` 函数，接收 { file: 预览文件, index: 当前预览的下标, imgList: 所有图片地址列表, resolve }，通过 `resolve` 函数告知组件是否确定通过，`resolve` 接受 1 个 boolean 值，`resolve(true)` 表示选项通过，`resolve(false)` 表示选项不通过，不通过时不会执行预览图片操作。
