Silverlight 后台代码与html_JavaScript 互访

1JavaScript访问silverlight函数

 

 public Page()
        {
            InitializeComponent();
            Loaded += new RoutedEventHandler(Page_Loaded);
        }
        void Page_Loaded(object sender, RoutedEventArgs e)
        {
            HtmlPage.RegisterScriptableObject("SilverlightLearn", this);
        }
        [ScriptableMember]
        public void SayHelloToMe(string firstName)
        {
            Block1.Text = string.Format("Hello {0}", firstName);
        }

 

 

 

 <script type="text/javascript">
 function sayHello(fname)
    {
        var slhost = document.getElementById("Xaml1");
        slhost.content.SilverlightLearn.SayHelloToMe(fname);
    }
 function buttonClick()
    {
        var f = document.getElementById("HtmlText1").value;
        sayHello(f);
    }
</script>

 

 <input onclick="buttonClick();" type="button" id="htmlButton1" value="Html Button" />

2 silverlighty页访问JavaScript函数

<script type="text/javascript">
    function sayGoodbye(fname)
    {
        var box = document.getElementById("HtmlText1");
        box.value = fname;
    }
    </script>

 

  //第一种方式
            ScriptObject jsObj = (ScriptObject)HtmlPage.Window.GetProperty("sayGoodbye");
            jsObj.InvokeSelf(TextBox1.Text);

            // 第二种方式
            HtmlPage.Window.Invoke("sayGoodbye",  "Tim", "Heuer" );
