HarmonyOS H5页面选择图片可以从onShowFileSelector 监听到，但是H5页面选择视频的时候，从onShowFileSelector监听不到。请问是从别的方法中监听吗？

H5页面选择视频的时候onShowFileSelector可以监听，参考如下文档和例子。

例子

@Entry
@Component
export struct WebComponent {
  controller: webview.WebviewController = new webview.WebviewController()

  build() {
    Column() {
      Web({ src: $rawfile('index.html'), controller: this.controller })
        .onShowFileSelector((event) => {
          if (event) {
            let photoSelectOptions = new photoAccessHelper.PhotoSelectOptions();
            let photoPicker = new photoAccessHelper.PhotoViewPicker();
            // 过滤选择媒体文件类型为IMAGE
            photoSelectOptions.MIMEType = photoAccessHelper.PhotoViewMIMETypes.IMAGE_VIDEO_TYPE;
            // 设置最大选择数量
            photoSelectOptions.maxSelectNumber = 5;
            // let chooseFile: picker.PhotoSelectResult = await photoPicker.select(photoSelectOptions);
            photoPicker.select(photoSelectOptions).then((res)=>{

              console.log('asd===',JSON.stringify(res.photoUris))

            }).catch((err:Error)=>{

            })
            console.log('res ===',JSON.stringify(event))
          }
          return true;
        })
    }
  }
}
