i write a qt program and a vue page.

const auto webview = new QWebEngineView;
const auto webpage = webview->page();
webview->load({ QLatin1String{"http://127.0.0.1:8080/#/xxx"} });

webpage can only use webpage->runJavaScript("a javascript string");

methods: {
    verify(){
        console.log(this.input)
