こんな風に使う。
cb.showWebPage(site_url, { showLocationBar: false });
オプションはこれら。
Available options: ・showLocationBar (Android and iOS): show/hide a location bar in the generated browser ・showAddress (Android and iOS): show/hide the address bar in the generated browser ・showNavigationBar (Android and IOS): show/hide the entire navigation bar. Important: since there is no "Done"-Button anymore, the ChildBrowser can only be closed with the api call close() (see below).
