What is the best way to retrieve the results from the event handler triggered by window.external.Notify("someText") in order to send them back to JavaScript?

Using window.external.Notify("someText") in my

Windows Phone 8 HTML5 Application

function func() 
{ 
   window.external.Notify("clearTextBox"); 
}

An event handler for ScriptNotify has been implemented

private void BrowserScriptNotify(object sender, NotifyEventArgs e)
{
        //Business logic goes here
}

The XAML code includes the following:

<phone:WebBrowser x:Name="Browser"
                          HorizontalAlignment="Stretch"
                          VerticalAlignment="Stretch"
                          Loaded="Browser_Loaded"
                          IsScriptEnabled="true"
                            ScriptNotify="BrowserScriptNotify"
                          NavigationFailed="Browser_NavigationFailed" />

Everything is functioning correctly, but how can I return results from the event handler back to JavaScript? Is calling a JavaScript function at the end of the event handler the best approach?

Answer №1

Indeed, when transitioning from one language to another, it is not possible to utilize return values.
The alternative approach is to establish a callback in the opposite direction to exchange results.
