ScriptReferenceEventArgs.Script Property

  • Reference

Definition

Namespace:
System.Web.UI
Assembly:
System.Web.Extensions.dll

Gets the ScriptReference object that contains the script library.

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

Property Value

ScriptReference

A ScriptReference object that contains the client script referenced on the Web page.

Examples

The following code example shows an ASP.NET Web page that references a script file that is named CustomScript.js. When the Web application is hosted on the www.contoso.com domain, the [ScriptReference.Path]Path property is set to a value specific for that domain. An event handler for the ResolveScriptReference event checks the host URL and changes the value for the [ScriptReference.Path]Path property if it is necessary. The ScriptReference object is retrieved through the Script property.
