如何从Nativescript WebView中读取网址？

<WebView src="https://www.example.com"></WebView>

import { WebView } from "tns-core-modules/ui/web-view";

export class MyComponent {
    webView: WebView;
}

import { WebView } from "tns-core-modules/ui/web-view";

export class MyComponent {
    webView: WebView;

    onLoaded(args) {
        this.webView = args.object;
    }
}

import { WebView } from "tns-core-modules/ui/web-view";

export class MyComponent {
    webView: WebView;

    onLoaded(args) {
        this.webView = args.object;
    }

    getWebViewUrl() {
        const currentUrl = this.webView.src;
        console.log(currentUrl);
    }
}
