{{APIRef("UI Events")}}
The KeyboardEvent.location read-only property returns an
unsigned long representing the location of the key on the keyboard or other
input device.
Possible values are:
<table class="standard-table"> <thead> <tr> <th>Constant</th> <th>Value</th> <th>Description</th> </tr> </thead> <tbody> <tr> <td><code>DOM_KEY_LOCATION_STANDARD</code></td> <td>0</td> <td> The key has only one version, or can't be distinguished between the left and right versions of the key, and was not pressed on the numeric keypad or a key that is considered to be part of the keypad. </td> </tr> <tr> <td><code>DOM_KEY_LOCATION_LEFT</code></td> <td>1</td> <td> The key was the left-hand version of the key; for example, the left-hand <kbd>Control</kbd> key was pressed on a standard 101 key US keyboard. This value is only used for keys that have more than one possible location on the keyboard. </td> </tr> <tr> <td><code>DOM_KEY_LOCATION_RIGHT</code></td> <td>2</td> <td> The key was the right-hand version of the key; for example, the right-hand <kbd>Control</kbd> key is pressed on a standard 101 key US keyboard. This value is only used for keys that have more than one possible location on the keyboard. </td> </tr> <tr> <td><code>DOM_KEY_LOCATION_NUMPAD</code></td> <td>3</td> <td> <p> The key was on the numeric keypad, or has a virtual key code that corresponds to the numeric keypad. </p> <div class="note"> <p> <strong>Note:</strong> When <kbd>NumLock</kbd> is locked, Firefox always returns <code>DOM_KEY_LOCATION_NUMPAD</code> for the keys on the numeric pad. Otherwise, when <kbd>NumLock</kbd> is unlocked and the keyboard actually has a numeric keypad, Firefox always returns <code>DOM_KEY_LOCATION_NUMPAD</code> too. On the other hand, if the keyboard doesn't have a keypad, such as on a notebook computer, some keys become Numpad only when NumLock is locked. When such keys fires key events, the location attribute value depends on the key. That is, it must not be <code>DOM_KEY_LOCATION_NUMPAD</code>. </p> </div> <div class="note"> <p> <strong>Note:</strong> <kbd>NumLock</kbd> key's key events indicate <code>DOM_KEY_LOCATION_STANDARD</code> both on Firefox and Internet Explorer. </p> </div> </td> </tr> <tr> <td> <code>DOM_KEY_LOCATION_MOBILE</code> {{Non-standard_inline()}} {{deprecated_inline}} </td> <td>4</td> <td> <p> The key was on a mobile device; this can be on either a physical keypad or a virtual keyboard. </p> </td> </tr> <tr> <td> <code>DOM_KEY_LOCATION_JOYSTICK</code> {{Non-standard_inline()}} {{deprecated_inline}} </td> <td>5</td> <td> <p> The key was a button on a game controller or a joystick on a mobile device. </p> </td> </tr> </tbody> </table>A number.
