ScriptReferenceEventArgs 类

定义

ResolveScriptReference 事件提供数据。

public ref class ScriptReferenceEventArgs : EventArgs
public class ScriptReferenceEventArgs : EventArgs
type ScriptReferenceEventArgs = class
    inherit EventArgs
Public Class ScriptReferenceEventArgs
Inherits EventArgs
继承
ScriptReferenceEventArgs

示例

以下示例演示引用名为 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)。

注解

呈现脚本引用时, ScriptReferenceEventArgs 对象包含 实例 ScriptReferenceScriptManager 定义的 对象。 可以为 事件创建事件处理程序,ResolveScriptReference以检查ScriptReference对象并根据需要对其进行修改。

构造函数

ScriptReferenceEventArgs(ScriptReference)

初始化 ScriptReferenceEventArgs 类的新实例。

属性

Script

获取包含脚本库的 ScriptReference 对象。

方法

Equals(Object)

确定指定对象是否等于当前对象。

(继承自 Object)
GetHashCode()

作为默认哈希函数。

(继承自 Object)
GetType()

获取当前实例的 Type

(继承自 Object)
MemberwiseClone()

创建当前 Object 的浅表副本。

(继承自 Object)
ToString()

返回表示当前对象的字符串。

(继承自 Object)
