Other helpful HTML5 features

All I would need is HTML5…

In a perfect world

When we need more, XAML to the rescue!Use InvokeScript to call JavaScript functions from host (C#)

webBrowser.InvokeScript(“myFunction", “myArg1”);webBrowser.InvokeScript(“eval”, “document.body.offsetHeight.toString()”);webBrowser.InvokeScript(“execScript”, myScript.ToString());

Use ScriptNotify to call host (C#) from JavaScript async

XAML: <WebBrowser ScriptNotify=“Browser_ScriptNotify” />JavaScript: window.external.notify(parameter);C#: private void Browser_ScriptNotify(object sender, NotifyEventArgs e)

// use e.value to retrieve parameter

But wait, there is more!Set the default background color

webBrowser.Background=“#ffff00”;

Easily navigate backward/forwardif (webBrowser.CanNavigateBack) webBrowser.GoBack();if (webBrowser.CanNavigateForward) webBrowser.GoForward();

Clear local cache and cookiesawait webBrowser.ClearCookiesAsync();await webBrowser.ClearInternetCacheAsync();

Load files directly from XAPwebBrowser.Navigate(new Uri("test.html", UriKind.Relative))

A final thought…

Yes, we are fast!
