Definitie

Naamruimte:
System.Web.Configuration
Assembly:
System.Web.dll

Hiermee wordt een waarde opgehaald die aangeeft of de browser het ACCESSKEY kenmerk HTML <a> (anker) en <input> elementen ondersteunt.

public:
 virtual property bool SupportsAccesskeyAttribute { bool get(); };
public virtual bool SupportsAccesskeyAttribute { get; }
member this.SupportsAccesskeyAttribute : bool
Public Overridable ReadOnly Property SupportsAccesskeyAttribute As Boolean

Waarde van eigenschap

Boolean

true als de browser het accesskey kenmerk HTML <a> (anker) en <input> elementen ondersteunt, falseanders. De standaardwaarde is false.

Voorbeelden

In het volgende codevoorbeeld ziet u hoe u kunt bepalen of de browser het accesskey kenmerk VAN HTML <a> (anker) en <input> elementen ondersteunt.

Opmerkingen

Het accesskey kenmerk breidt het beheer van formulieren en koppelingen op een webpagina uit naar mobiele en toegankelijke platforms door een zachte sleutel of een andere controller op het apparaat toe te wijzen om te communiceren met HTML <a> (anker) en <input> elementen.
