Can I catch web/javascript event on built-in web browser?

Hello,

Is there any way to catch or hook web/javascript event ?

I tried built-in web browser, which is beta, but I cannot find the way to get those events.

I want to get events on PC, Android, iOS platform. How can i achieve this?

Take a look at WebViewControl.java for Android. Some Javascript events are forwarded to AndroidWebBrowserWidget.cpp from the browser.
