## 文件选择数量限制
665+
666+
不同平台的文件选择方法具有不同的最大选择数量限制，这些限制由 uni-app 平台 API 本身决定：
667+
668+
### 微信平台
669+
670+
微信小程序平台具有更丰富的文件选择能力和更高的数量上限：
671+
672+
| 选择方法 | 最大选择数量 | 说明 | 适用文件类型 |
673+
| -------- | ------------ | ---- | ------------ |
674+
| `chooseMedia` | 20 | 选择图片和视频时的最大数量限制 | accept 为 `image`、`video` 或 `media` 时使用 |
675+
| `chooseMessageFile` | 100 | 从客户端会话选择文件时的最大数量限制 | accept 为 `file` 或 `all` 时使用 |
676+
677+
### H5平台
678+
679+
H5 平台支持多种文件选择方式：
680+
681+
| 选择方法 | 最大选择数量 | 说明 | 适用文件类型 |
682+
| -------- | ------------ | ---- | ------------ |
683+
| `chooseImage` | 9 | 选择图片时的最大数量限制 | accept 为 `image` 时使用 |
684+
| `chooseVideo` | 1 | 不支持多选，只能选择单个视频文件 | accept 为 `video` 时使用 |
685+
| `chooseFile` | 100 | 选择文件时的最大数量限制 | accept 为 `all` 时使用 |
686+
687+
::: warning H5平台特别说明
688+
count 值在 H5 平台的表现基于浏览器本身的规范。目前测试结果来看，只能限制单选/多选，并不能限制具体数量。并且，在实际的手机浏览器中很少有能够支持多选的。
689+
:::
690+
691+
### 其他平台
692+
693+
其他平台（如支付宝小程序、钉钉小程序、App等）的文件选择能力相对有限：
694+
695+
| 选择方法 | 最大选择数量 | 说明 | 适用文件类型 |
696+
| -------- | ------------ | ---- | ------------ |
697+
| `chooseImage` | 9 | 选择图片时的最大数量限制 | accept 为 `image` 时使用 |
698+
| `chooseVideo` | 1 | 不支持多选，只能选择单个视频文件 | accept 为 `video` 时使用 |
699+
700+
::: tip 提示
701+
- 当设置的 `limit` 或 `maxCount` 超过上述平台限制时，实际选择数量将以平台限制为准
702+
- 微信小程序平台优先使用 `chooseMedia` 来选择图片和视频，具有更高的选择数量上限
703+
- 视频选择在非微信平台受限于 `chooseVideo` API，仅支持单选
704+
- 平台能力的优先级：微信平台 > H5平台 > 其他平台

114+
- 视频选择在大多数平台都不支持多选
115+

## File Selection Quantity Limits
122+
123+
Different platforms have different file selection methods with varying maximum quantity limits, which are determined by the uni-app platform APIs:
124+
125+
### WeChat Platform
126+
127+
WeChat Mini Program platform offers richer file selection capabilities with higher quantity limits:
128+
129+
| Selection Method | Maximum Count | Description | Applicable File Types |
130+
| ---------------- | ------------- | ----------- | -------------------- |
131+
| `chooseMedia` | 20 | Maximum selection count for images and videos | Used when accept is `image`, `video`, or `media` |
132+
| `chooseMessageFile` | 100 | Maximum selection count for files from client sessions | Used when accept is `file` or `all` |
133+
134+
### H5 Platform
135+
136+
H5 platform supports multiple file selection methods:
137+
138+
| Selection Method | Maximum Count | Description | Applicable File Types |
139+
| ---------------- | ------------- | ----------- | -------------------- |
140+
| `chooseImage` | 9 | Maximum selection count for images | Used when accept is `image` |
141+
| `chooseVideo` | 1 | Does not support multiple selection, single video file only | Used when accept is `video` |
142+
| `chooseFile` | 100 | Maximum selection count for files | Used when accept is `all` |
143+
144+
::: warning H5 Platform Special Note
145+
The behavior of the count value on the H5 platform is based on the browser's own specifications. Current test results show that it can only limit single/multiple selection, but cannot limit the specific quantity. Moreover, very few mobile browsers actually support multiple selection.
146+
:::
147+
148+
### Other Platforms
149+
150+
Other platforms (such as Alipay Mini Program, DingTalk Mini Program, App, etc.) have relatively limited file selection capabilities:
151+
152+
| Selection Method | Maximum Count | Description | Applicable File Types |
153+
| ---------------- | ------------- | ----------- | -------------------- |
154+
| `chooseImage` | 9 | Maximum selection count for images | Used when accept is `image` |
155+
| `chooseVideo` | 1 | Does not support multiple selection, single video file only | Used when accept is `video` |
156+
157+
::: tip Tips
158+
- When the set `limit` or `maxCount` exceeds the above platform limits, the actual selection count will be subject to platform limits
159+
- WeChat Mini Program platform prioritizes using `chooseMedia` for selecting images and videos, which has higher selection count limits
160+
- Video selection on non-WeChat platforms is limited by the `chooseVideo` API and only supports single selection
161+
- Platform capability priority: WeChat Platform > H5 Platform > Other Platforms

:::
157+
158+
::: warning maxCount Parameter Limitation
159+
The `maxCount` parameter in `ChooseFileOption` is limited by the underlying platform APIs. Setting a value higher than the platform limit will be automatically capped to the maximum supported value.
