HarmonyOS 鸿蒙Next 在鸿蒙 import { webview } from '@kit.ArkWeb'中 js如何和webview通信？

  js如何和webview通信方式就是你看到的方式，关于 javaScriptProxy方法里的参数object, name, methodList要与js保持一致，可参考以下链接：

   console.log('Web Component toString' + param);
 }
}

         }
       })
     Button('Register JavaScript To Window')
       .onClick(() => {

         }
       })
     Web({ src: $rawfile('index.html'), controller: this.webviewController })
   }
 }
