HarmonyOS Web组件的onShowFileSelector拿不到网页input组件的accept参数？

    例如：

    <input type="file" name="image" maxlength="1" accept="image/*">

    Web组件的onShowFileSelector返回的参数拿不到上面的accept里的"image/*的值，分不清是要用文件还是图片还是视频。

      可以在h5中定义一个获取accept的函数，然后在web组件合适的时机获取accept，参考示例如下：

      1.index.ets

      // xxx.ets
import web_webview from '@ohos.web.webview';
import picker from '@ohos.file.picker';
import { BusinessError } from '@ohos.base';

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

  build() {
    Column() {
      Web({ src: $rawfile('index.html'), controller: this.controller })
        .onPageEnd(e => {
        })
        .onShowFileSelector((event) => {
          console.log('MyFileUploader onShowFileSelector invoked')
          const documentSelectOptions = new picker.DocumentSelectOptions();
          let uri: string | null = null;
          const documentViewPicker = new picker.DocumentViewPicker();
          documentViewPicker.select(documentSelectOptions).then((documentSelectResult) => {
            uri = documentSelectResult[0];
            try {
              this.controller.runJavaScript(
                'test()',
                (error, result) => {
                  if (error) {
                    console.error(`run JavaScript error, ErrorCode: ${(error as BusinessError).code},  Message: ${(error as BusinessError).message}`);
                    return;
                  }
                  if (result) {
                    //这里是要获取的accept
                    console.log(result);
                  }
                });
            } catch (error) {
              console.error(`ErrorCode: ${(error as BusinessError).code},  Message: ${(error as BusinessError).message}`);
            }
            console.info('documentViewPicker.select to file succeed and uri is:' + uri);
            if (event) {
              event.result.handleFileList([uri]);
            }
          }).catch((err: BusinessError) => {
            console.error(`Invoke documentViewPicker.select failed, code is ${err.code}, message is ${err.message}`);
          })
          return true
        })
    }
  }
}

      2.index.html

      <!DOCTYPE html>
  <html>
  <head>
  <meta charset="utf-8">
  <title>Document</title>
  </head>

  <body>
  <!-- 点击上传文件按钮 -->
  <input type="file" id="name" name="image" maxlength="1" accept="image/*"></br>
  <meta name="viewport" content="width=device-width" />
  </body>
  <script type="text/javascript">
  function test() {
    const fileInput =  document.getElementById("name")
    return fileInput.accept
  }
  </script>
  </html>
