HarmonyOS 怎么给H5传递JSONObject对象

controller: web_webview.WebviewController = null!;
this.controller.runJavaScript(`callMessageByFlowNo(${flowNo},${result})`);

通过这种方法，怎么给H5传递JSONObject对象，而不是string类型

jsResult.handlePromptConfirm(JSON.stringify(result))应该怎么传递json对象

参考demo:

import { webview } from '@kit.ArkWeb';
import { BusinessError } from '@kit.BasicServicesKit';

class Result {
  a:number
  b:string

  constructor(a: number, b: string) {
    this.a = a;
    this.b = b;
  }
}

@Entry
@Component
struct WebComponent {
  controller: webview.WebviewController = new webview.WebviewController();
  @State webResult: string = '';
  result:Result = new Result(1,'1')
  build() {
    Column() {
      Text(this.webResult).fontSize(20)
      Web({ src: $rawfile('index4.html'), controller: this.controller })
        .javaScriptAccess(true)
        .onPageEnd(e => {
          try {
            this.controller.runJavaScript(`test(${JSON.stringify(this.result)})`,
              (error, result) => {
                if (error) {
                  console.error(`run JavaScript error, ErrorCode: ${(error as BusinessError).code},  Message: ${(error as BusinessError).message}`);
                  return;
                }
                if (result) {
                  this.webResult = result;
                  console.info(`The test() return value is: ${result}`);
                }
              });
            if (e) {
              console.info('url: ', e.url);
            }
          } catch (error) {
            console.error(`ErrorCode: ${(error as BusinessError).code},  Message: ${(error as BusinessError).message}`);
          }
        })
    }
  }
}
