備註

裝置功能範例示範如何偵測輸入裝置是否存在，以及擷取每個裝置的功能和屬性。

下列程式碼示範如何建立這個類別的實例，並用它來判斷鍵盤是否存在。

function getKeyboardCapabilities() {
  var keyboardCapabilities = new Windows.Devices.Input.KeyboardCapabilities();
  id("keyboardPresent").innerHTML = keyboardCapabilities.keyboardPresent;
}

建構函式

KeyboardCapabilities()

初始化 KeyboardCapabilities 類別的新實例。

屬性

KeyboardPresent

取得值，指出是否偵測到裝置將本身識別為鍵盤。
