Nativescript: Prevent WebView from loading specific URL

Created on 1 Nov 2017 · 5Comments · Source: NativeScript/NativeScript

Looking into the source code for both iOS and Android, it looks there is no way to prevent a WebView from loading a specific URL.

Am I missing something?

If not, we need this functionality and most probably we'll implement it in a fork of {N} and create a PR if this is something anybody else would need.

Hi @surdu,
In your case, you could use loadStartedEvent to validate the url and if needed to stop page loading while using stopLoading() method. For example:

    webview.on(WebView.loadStartedEvent, (args: LoadEventData)=>{
        if(args.url === "url"){
            (<WebView>args.object).stopLoading();
        }
    })

Let me know if this helps in your case.

The stopLoading seems sometimes not working for Android platform, sometimes it still loading and redirect to the specific url
