关于webbrowser

 

1，加载本地html文件

using System.IO; using Microsoft.Xna.Framework; 

StreamReader reader = new StreamReader( TitleContainer.OpenStream( "html/wp7wiki.html"));

Browser.NavigateToString(reader.ReadToEnd());

2，默认不开script，用isscriptenabled开启

XAML

< phone : WebBrowser x : Name ="Browser" IsScriptEnabled ="True" />

C#

Browser.IsScriptEnabled = true;

 

3, 在你的app和script 之间传递信息

若要把数据从app传到page，可以简单的调用.InvokeScript(). 他有两个重载函数，无参和有参：

public Object InvokeScript( string scriptName )

public Object InvokeScript( string scriptName, params Object[] args ) s

criptName是脚本的函数名，args是函数的参数列表，如： string returnValue = ( string)Browser.InvokeScript( "getText", "http://jeffblankenburg.com", "rocks", "awesomely"); 

 

若相反，即从script传数据到app， 首先script要触发一个scriptnotify事件：window.external.Notify( http://jeffblankenburg.com);（以传url为例）然后在app中设置一个notify event handle：.ScriptNotify.

void Browser_ScriptNotify( object sender, NotifyEventArgs e) { Browser.Navigate( new Uri(e.Value, UriKind.Absolute)); } 

//NotifyEventArgs.Value是script传递的数据

 

4，可以使用进度条来表示正在加载页面

XAML

< ProgressBar Foreground ="Orange" x : Name ="ProgBar" Visibility ="Collapsed" IsIndeterminate ="True" Height ="4" HorizontalAlignment ="Left" Margin ="10,66,0,0" VerticalAlignment ="Top" Width ="460" />

C#

void Browser_Navigating( object sender, NavigatingEventArgs e) { ProgBar.Visibility = Visibility.Visible; } void Browser_Navigated( object sender, System.Windows.Navigation. NavigationEventArgs e) { ProgBar.Visibility = Visibility.Collapsed; }
