Need to get callback from webpage to my "WebView" in C# using scriptnotify. But it's not working.
I hosted a webpage locally using node js. Webpage is as below.
<!DOCTYPE html>
<html>
<body>
<h1>The onclick Event</h1>
<button onclick="myFunction()">Click me</button>
<p id="demo"></p>
<script>
function myFunction() {
document.getElementById("demo").innerHTML = "latest";
window.external.notify('The script says the doubled value is ' );
}
</script>
</body>
</html>
After that created a UWP app to open the webpage using webview. Added window.external.notify in the JS to get the call back. But not getting the same.
//C# code to get the callback
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
//Added the notification handler here
webView.ScriptNotify += webView_ScriptNotify;
//Navigating to the local page
webView.Navigate(new Uri("http://localhost:8080/"));
}
async void webView_ScriptNotify(object sender, NotifyEventArgs e)
{
//Kept break point here , but it's not getting hit any time.
var jsScriptValue = e.Value;
Debug.WriteLine("Send to debug output.");
}
}
//Added a web view control in xaml file
<Grid>
<WebView x:Name="webView" Height="500"> </WebView>
</Grid>
