    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
            load_map();
        }
        void load_map()
        {
            // Load HTML document as a string
            Browser.IsScriptEnabled = true;
            Uri uri = new Uri("test2.html", UriKind.Relative);
            Stream stream = Application.GetResourceStream(uri).Stream;
            using (StreamReader reader = new StreamReader(stream))
            {
                // Navigate to HTML document string
                Browser.NavigateToString(reader.ReadToEnd());
            }
        }
        private void button1_Click(object sender, RoutedEventArgs e)
        {
            NavigationService.Navigate(new Uri("/Page1.xaml", UriKind.Relative));
        }

        protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
        {
            base.OnNavigatedTo(e);

            string msg = "";

            if (NavigationContext.QueryString.TryGetValue("act", out msg))
            {
                string[] result = msg.Split('|');
                string content_text = result[1];
                switch (result[0])
                {
                    case "1": load(content_text); break;
                    default: break;
                }
            }
        }
        void load(string text)
        {

            Browser.InvokeScript("load", text);

        }
    }
}
