public virtual bool SupportsJPhoneMultiMediaAttributes { get; }
member this.SupportsJPhoneMultiMediaAttributes : bool
Public Overridable ReadOnly Property SupportsJPhoneMultiMediaAttributes As Boolean

屬性值

Boolean

true若瀏覽器支援 J-Phone 多媒體屬性;否則，。 false 預設值為 false。

範例

以下程式碼範例說明如何判斷瀏覽器是否支援 J-Phone 多媒體屬性。

備註

此 SupportsJPhoneMultiMediaAttributes 特性僅適用於相容 J-Phone 的行動裝置。

J-Phone 是一種基於 HTML 的標記語言規範，適用於相容 J-Phone 的瀏覽器。 若 true，瀏覽器支援額外的屬性以設定 HTML <a> （錨點）及 <select> 元素。 支援的額外屬性如下：

  • src

  • soundstart

  • loop

  • volume

  • vibration

  • viblength
