通过

ScriptReferenceEventArgs.Script 属性

  • 参考

定义

命名空间:
System.Web.UI
程序集:
System.Web.Extensions.dll

获取包含脚本库的 ScriptReference 对象。

public:
 property System::Web::UI::ScriptReference ^ Script { System::Web::UI::ScriptReference ^ get(); };
public System.Web.UI.ScriptReference Script { get; }
member this.Script : System.Web.UI.ScriptReference
Public ReadOnly Property Script As ScriptReference

属性值

ScriptReference

一个 ScriptReference 对象，包含在网页上引用的客户端脚本。

示例

下面的代码示例演示引用名为 CustomScript.js 的脚本文件的 ASP.NET 网页。 当 Web 应用程序托管在域上 www.contoso.com 时，[ScriptReference.Path]Path 属性设置为特定于该域的值。 事件的事件处理程序 ResolveScriptReference 检查主机 URL，并更改 [ScriptReference.Path]Path 属性的值（如有必要）。 通过 ScriptReferenceScript 属性检索 对象。

注解

引发ScriptReference事件时ResolveScriptReference， Script 属性中的 对象将添加到 Scripts 属性中。
