HttpCapabilitiesBase.SupportsAccesskeyAttribute 屬性

  • 參考

定義

命名空間:
System.Web.Configuration
組件:
System.Web.dll

取得值，指出瀏覽器是否支援 HTML ACCESSKEY (錨定) 和 <a> 項目的 <input> 屬性。

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

屬性值

Boolean

如果瀏覽器支援 HTML <a> (錨點) 和 <input> 項目的 accesskey 屬性，則為 true；否則為 false。 預設為 false。

範例

下列程式碼範例示範如何判斷瀏覽器是否支援 accesskey HTML <a> (錨點) 和 <input> 元素的 屬性。

備註

屬性 accesskey 藉由指派裝置上的軟鍵或其他控制器來與 HTML <a> (錨點) 和元素互動，將網頁上表單和連結的控制項延伸至行動和 <input> 無障礙平臺。
