[zhuzhi]

<input id="Button1" type="button" value="button" onclick="setSilverlight()" />

<script type="text/javascript">
function setSilverlight() {
silverlight = document.getElementById("Xaml1"); //引用Silverlight插件到一个对象
var Rectangle0 = silverlight.content.FindName("r01"); //将Sl中的矩形r01引用到一个对象
Rectangle0["Height"]="300"; //设置举行的高为300
//alert(Rectangle0["Height"]); //读取矩形的高
}
</script>

<asp:Silverlight ID="Xaml1" runat="server" Source="~/ClientBin/html_set_sl.xap" MinimumVersion="2.0.30523" Width="100%" Height="100%" />

使用ScriptableMember和ScriptableType属性可以实现。

[ScriptableType()]
public partial class ScriptableSilverlight : UserControl
{
public ScriptableSilverlight()
{
InitializeComponent();
HtmlPage.RegisterScriptableObject("Page", this);
}
[ScriptableMember()]
public void ChangeText(string newText)
{
lbl.Text = newText;
}
}

<script type="text/javascript">
function updateSilverlightText()
{
var control = document.getElementById("silverlightControl");
control.content.Page.ChangeText(
"This TextBlock has been updated through JavaScript.");
}
</script>

在HTML可以调用
[code=HTML]
<p onclick="updateSilverlightText()">Click here to change the Silverlight
TextBlock.</p>

[/code]
