--- title: KeyboardEvent.keyCode slug: Web/API/KeyboardEvent/keyCode translation_of: Web/API/KeyboardEvent/keyCode ---

非推奨の KeyboardEvent.keyCode 読み取り専用プロパティは、押されたキーの変更されていない値を識別するシステムおよび実装に依存する数値コードを表します。これは通常、キーに対応する 10進 ASCII ({{RFC(20)}}) またはWindows 1252 コードです。キーを識別できない場合は、この値は 0 になります。

これはしばらくの間、非推奨とされています。その代わりに、{{domxref("KeyboardEvent.code")}} が実装されている場合は、{{domxref("KeyboardEvent.code")}} を使うべきです。残念ながら、いくつかのブラウザはまだこれを持っていないので、すべてのターゲットブラウザでサポートされているものを使うように注意しなければなりません。

Web 開発者は、keydown 及び keyup イベントを扱う際に、印刷可能な文字に対して keyCode 属性を使用すべきではありません。上述したように、keyCode 属性は、印刷可能な文字、特に Shift キーや Alt キーが押された状態で入力された文字には有用ではありません。ショートカットキーハンドラを実装する場合、{{event("keypress")}} イベントの方が通常は良いでしょう (少なくとも Gecko が使用中のランタイムの場合)。詳細は Gecko Keypress Event を参照してください。

例

window.addEventListener("keydown", function (event) {
  if (event.defaultPrevented) {
    return; // デフォルトのアクションがキャンセルされている場合は何もしないようにします。
  }

  var handled = false;
  if (event.key !== undefined) {
    // KeyboardEvent.key でイベントを処理し、handled を true に設定します。
  } else if (event.keyCode !== undefined) {
    // KeyboardEvent.keyCode でイベントを処理し、handled を true に設定します。
  }

  if (handled) {
    // イベントが処理された場合、"ダブルアクション" を抑制する
    event.preventDefault();
  }
}, true);

keyCodeの値

標準位置で印刷可能なキー

標準位置で印刷可能なキーを押したり離したりすることで発生するキーイベントの値は、ブラウザ間で互換性がありません。

IE just exposes the native virtual keycode value as KeyboardEvent.keyCode.

Google Chrome, Chromium and Safari must decide the value from the input character. If the inputting character can be inputted with the US keyboard layout, they use the keyCode value on the US keyboard layout.

Starting in Firefox 15 {{geckoRelease("15.0")}}, Gecko gets keyCode values from ASCII characters inputtable by the key — even with shift modifiers or an ASCII capable keyboard layout. See the following rules for details:

If the system is Windows and the native keycode of the pressed key indicates that the key is a-z or 0-9, use a keycode for it.
If the system is Mac and the native keycode of the pressed key indicates that the key is 0-9, use a keycode for it.
If the pressed key inputs an ASCII alphabetic or numeric character with no modifier key, use a keycode for it.
If the pressed key inputs an ASCII alphabetic or numeric character with a Shift key modifier, use a keycode for it.
If the pressed key inputs a different ASCII character with no modifier key, use a keycode for it.
If the pressed key inputs a different ASCII character with a Shift key modifier, use a keycode for it.
Otherwise, i.e., pressed key inputs a unicode character:
1. If the keyboard layout is ASCII-capable (i.e., can input ASCII alphabets), use 0 or compute with the following additional rules.
2. Otherwise, i.e., the keyboard layout isn't ASCII capable, use the ASCII capable keyboard layout installed on the environment with the highest priority:
  1. If the pressed key on the alternative keyboard layout inputs an ASCII alphabetic or numeric character, use a keycode for it.
  2. Otherwise, use 0 or compute with the following additional rules.

Starting in Firefox 60 {{geckoRelease("60.0")}}, Gecko sets keyCode values of punctuation keys as far as possible (when points 7.1 or 7.2 in the above list are reached) with the following rules:

The purpose of these new additional rules is for making users whose keyboard layouts map unicode characters to punctuation keys in a US keyboard layout can use web applications which support Firefox only with ASCII-capable keyboard layouts or just with a US keyboard layout. Otherwise, the newly mapped keyCode values may be conflict with other keys. For example, if the active keyboard layout is Russian, the keyCode value of both the "Period" key and "Slash" key are 190 (KeyEvent.DOM_VK_PERIOD). If you need to distinguish those keys but you don't want to support all keyboard layouts in the world by yourself, you should probably use {{domxref("KeyboardEvent.code")}}.

If running macOS or Linux:
1. If the active keyboard layout is not ASCII-capable and an alternative ASCII-capable keyboard layout is available.
  1. If the alternative ASCII-capable keyboard layout produces an ASCII character via just the unmodified key, use a keyCode for the character.
  2. If the alternative ASCII-capable keyboard layout produces an ASCII character with a Shift key modifier, use a keyCode for the shifted character.
  3. Otherwise, use a keyCode for an ASCII character produced by the key when the US keyboard layout is active.
2. Otherwise, use a keyCode for an ASCII character produced by the key when the US keyboard layout is active.
If running on Windows:
1. Use a keyCode value for an ASCII character produced by a key which is mapped to the same virtual keycode of Windows when the US keyboard layout is active.

*1 The value is input from JIS keyboard. When you use ANSI keyboard, the keyCode value and inputted character are what you select from the US keyboard layout.

*2 The key is a dead key. The value of keyup event is 0xBA (186).

*3 The key is a dead key. The value of keyup event is 0x10 (16).

*4 No key events are fired.

*5 The key isn't available with Greek keyboard layout (does not input any character). The value of keyup event is 0x00 (0).

*1 On Windows, "AltGraph" key causes "ControlLeft" key event and "AltRight" key event.

*2 When Japanese keyboard layout is active, "CapsLock" key without Shift causes 0xF0 (240). The key works as "Alphanumeric" key whose label is "英数".

*3 When Japanese keyboard layout is active, "CapsLock" key without Shift causes 0x00 (0). The key works as "Alphanumeric" key whose label is "英数".

*1 keypress event is fired whose keyCode and charCode are 0x10 (16) but text isn't inputted into editor.

*2 On Mac, "Help" key is mapped to "Insert" key of PC keyboard. These keyCode values are the same as the "Insert" key's keyCode value.

*3 Tested on Fedora 20.

*4 Only keyup event is fired.

*5 PC's "PrintScreen", "ScrollLock" and "Pause" are mapped to Mac's "F13", "F14" and "F15". Chrome and Safari map same keyCode values with Mac's keys.

*6 "Pause" key with Control causes 0x03 (3).

*2 PC's "PrintScreen", "ScrollLock" and "Pause" are mapped to Mac's "F13", "F14" and "F15". Firefox maps same keyCode values with PC's keys.

*3 Tested on Fedora 20. The keys don't cause GDK_Fxx keysyms. If the keys cause proper keysyms, these values must be same as IE.

*4 Tested on Fedora 20. The keys don't cause DOM key events on Chromium.

*5 keyUp event's keyCode value is 0x83 (131).

*6 Tested on Fedora 20. The keys don't cause DOM key events on Firefox.

*7 Only keydown event is fired.

*8 No DOM key events are fired on Firefox.

OEM specific keys on Windows

On Windows, some values of virtual keycode are defined (reserved) for OEM specific key. They are available for special keys on non-standard keyboard. In other words, some values are used for different meaning by two or more vendors (or hardware).

Starting Gecko 21 (and older than 15), OEM specific key values are available on the keyCode attribute only on Windows. So they are not useful for usual web applications. They are useful only for intranet applications or in similar situations.

See "Manufacturer-specific Virtual-Key Codes (Windows CE 5.0)" in MSDN for the detail.
