KeyboardLayoutMap

KeyboardLayoutMap.entries Read only Experimental

Returns an array of a given object's own enumerable property [key, value] pairs, in the same order as that provided by a for...in loop (the difference being that a for-in loop enumerates properties in the prototype chain as well).

KeyboardLayoutMap.keys Read only Experimental

Returns a new array iterator object that contains the keys for each index in the array.

KeyboardLayoutMap.size Read only Experimental

Returns the number of elements in the KeyboardLayoutMap object.

KeyboardLayoutMap.values Read only Experimental

Returns a new array iterator object that contains the values for each index in the KeyboardLayoutMap object.

KeyboardLayoutMap.forEach() Read only Experimental

Executes a provided function once for each element of KeyboardLayoutMap.

KeyboardLayoutMap.get() Experimental

Returns the element with the given key from the KeyboardLayoutMap object.

KeyboardLayoutMap.has() Experimental

Returns a boolean indicating whether the KeyboardLayoutMap object has an element with the specified key.

The following example demonstrates how to get the location- or layout-specific string associated with the key that corresponds to the 'W' key on an English QWERTY keyboard.

const keyboard = navigator.keyboard;
keyboard.getLayoutMap().then((keyboardLayoutMap) => {
  const upKey = keyboardLayoutMap.get("KeyW");
  window.alert(`Press ${upKey} to move up.`);
});
