HttpCapabilitiesBase.CanRenderOneventAndPrevElementsTogether 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共存在相同 WML 卡中的 WML <onevent> 和 <prev> 項目。

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

屬性值

Boolean

如果瀏覽器支援 WML true 和 <onevent> 項目共存在相同的 WML 卡中，則為 <prev>，否則為 false。 預設為 true。

範例

下列程式碼範例示範如何判斷瀏覽器是否支援 WML，以及 <prev> 存在於相同 WML <onevent> 記憶卡內的元素。

備註

屬性 CanRenderOneventAndPrevElementsTogether 僅適用于 WML 相容的行動裝置。

如果 false 為 ，則不會正確轉譯在相同 WML 記憶卡內的 WML <onevent> 和 <prev> 元素。
