What is the alternative to `alert` in metro apps?

Question

I created my first app on Windows 8 vs 2012 and it runs and works fine. But when I try to say \"helloworld\" from JavaScript like this:

alert(\"Hello World\         


        

Answer 1

Remember that alert is not a JavaScript function, it's a browser (host) function, therefore, it's not available in non browser environments.

This link tells you to do the following

• Replace all alert functions with firing an event window.external.notify("message");

• Use scriptnotify event in webview to get that message.

• Show metro own dialog: MessageDialog
