Свойства

Свойства	Тип	Описание
`target` {{readonlyInline}}	EventTarget	Цель события (самая верхняя цель в дереве DOM).
`type` {{readonlyInline}}	DOMString	Тип события.
`bubbles` {{readonlyInline}}	Boolean	Whether the event normally bubbles or not
`cancelable` {{readonlyInline}}	Boolean	Отменяется ли событие или нет
`view` {{readonlyInline}}	WindowProxy	`document.defaultView` (`window` of the document)
`detail` {{readonlyInline}}	`long` (`float`)	0.
`target` {{readonlyInline}}	EventTarget (DOM element)	Сосредоточенный элемент, обрабатывающий ключевое событие, корневой элемент, если не выделен подходящий элемент ввода.
`char` {{readonlyInline}}	DOMString (string)	The character value of the key. If the key corresponds to a printable character, this value is a non-empty Unicode string containing that character. If the key doesn't have a printable representation, this is an empty string. See key names and char values for the detail. Примечание: Если ключ используется в качестве макроса, который вставляет несколько символов, значением этого атрибута является вся строка, а не только первый символ.
`key` {{readonlyInline}}	DOMString (string)	The key value of the key represented by the event. If the value has a printed representation, this attribute's value is the same as the `char` property. Otherwise, it's one of the key value strings specified in Key values. If the key can't be identified, its value is the string "Unidentified". See key names and char values for more details. Read Only.
`code` {{readonlyInline}}	DOMString (string)	Holds a string that identifies the physical key being pressed. The value is not affected by the current keyboard layout or modifier state, so a particular key will always return the same value.
`charCode` {{readonlyInline}}	Unsigned long (int)	The Unicode reference number of the key; this attribute is used only by the `keypress` event. For keys whose `char` attribute contains multiple characters, this is the Unicode value of the first character in that attribute. Warning: This attribute is deprecated; you should use `char` instead, if available.
`keyCode` {{readonlyInline}}	Unsigned long (int)	A system and implementation dependent numerical code identifying the unmodified value of the pressed key. This is usually the decimal ASCII ({{ RFC(20) }}) or Windows 1252 code corresponding to the key; see {{ anch("Virtual key codes") }} for a list of common values. If the key can't be identified, this value is 0. Warning: This attribute is deprecated; you should use `key` instead, if available.
`which` {{readonlyInline}}	Unsigned long (int)	A system and implementation dependent numeric code identifying the unmodified value of the pressed key; this is usually the same as `keyCode`. Warning: This attribute is deprecated; you should use `key` instead, if available.
`location` {{readonlyInline}}	long (float)	The location of the key on the device.
`repeat` {{readonlyInline}}	boolean	`true` if a key has been depressed long enough to trigger key repetition, otherwise `false`.
`locale` {{readonlyInline}}	string	The language code for the key event, if available; otherwise, the empty string.
`ctrlKey` {{readonlyInline}}	boolean	`true` if the control key was down when the event was fired. `false` otherwise.
`shiftKey` {{readonlyInline}}	boolean	`true` if the shift key was down when the event was fired. `false` otherwise.
`altKey` {{readonlyInline}}	boolean	`true` if the alt key was down when the event was fired. `false` otherwise.
`metaKey` {{readonlyInline}}	boolean	`true` if the meta key was down when the event was fired. `false` otherwise.

key {{readonlyInline}}

DOMString (string)

The key value of the key represented by the event. If the value has a printed representation, this attribute's value is the same as the char property.

Warning: This attribute is deprecated; you should use char instead, if available.

keyCode {{readonlyInline}}

Unsigned long (int)

A system and implementation dependent numerical code identifying the unmodified value of the pressed key. This is usually the decimal ASCII ({{ RFC(20) }}) or Windows 1252 code corresponding to the key; see {{ anch("Virtual key codes") }} for a list of common values. If the key can't be identified, this value is 0.

Заметки

Chrome не запускает событие keypress для известных сочетаний клавиш (reference). Какие сочетания клавиш известны, зависит от системы пользователя. Используйте событиеkeydown для реализации сочетаний клавиш.

<!DOCTYPE html> <html> <head> <script> 'use strict'; document.addEventListener('keypress', (event) => { const keyName = event.key; alert('keypress event\n\n' + 'key: ' + keyName); }); </script> </head> <body> </body> </html>
