Windows Phone 7.1中的JavaScript

Question

I am creating a Windows 7.1 Phone app where I am using webbrowser to display an ePUB book. I want to add to this html file a JavaScript script and to know how to enable JavaScript in the browser object in my app? I have set the IsScriptEnabled property to true but that does not seem to help.

Any ideas? Thanks in advance.

For example, you can add js code to html page:

Xaml file

 <phone:WebBrowser Name="webBrowser" Height="500" HorizontalAlignment="Stretch" VerticalAlignment="Top" IsScriptEnabled="True" ScriptNotify="webBrowser_ScriptNotify"/>

Cs file

private void scrollTo_Click(object sender, RoutedEventArgs e)
    {
        string H = y.Text;
        webBrowser.InvokeScript("scroll", H);
    }

    private void getscroll_Click(object sender, RoutedEventArgs e)
    {
        webBrowser.InvokeScript("getScroll");
    }

    private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
    {
            StreamReader reader = new StreamReader(TitleContainer.OpenStream("page.html"));
            string content = "<script language=\"JavaScript\">"
                + "function scroll(H)"
                + "{"
                + "window.scrollTo(0, H);"
                + "}"
                + "function getScroll()"
                + "{"
                + "var body = document.body;"
                + "var docElem = document.documentElement;"
                + "var Y = window.pageYOffset || docElem.scrollTop || body.scrollTop;"
                + "window.external.Notify(\"\"+Y);"
                + "}"
                + "</script>"
                + reader.ReadToEnd();
            webBrowser.NavigateToString(content);
    }

    private void webBrowser_ScriptNotify(object sender, NotifyEventArgs e)
    {
        y.Text = e.Value;
    }
