Properties

Property Type Description
target Read only EventTarget The event target (the topmost target in the DOM tree).
type Read only DOMString The type of event.
bubbles Read only boolean Does the event normally bubble?
cancelable Read only boolean Is it possible to cancel the event?
view Read only WindowProxy document.defaultView (the window of the document).
detail Read only long (float) 0.
target EventTarget (DOM element) Focused element processing the key event, root element if no suitable input element focused.
char Read only Unimplemented (see bug 680830) 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.
Note: If the key is used as a macro that inserts multiple characters, this attribute's value is the entire string, not just the first character.
key Unimplemented (see bug 680830) 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 attribute. Otherwise, it's one of the key value strings specified in {{ anch("Key values") }}. If the key can't be identified, this is the string "Unidentified". See key names and char values for the detail. Read Only.
charCode Read only 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 Read only 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 Read only 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 Read only long (float) The location of the key on the device.
repeat Read only Unimplemented boolean true if a key has been depressed long enough to trigger key repetition, otherwise false.
locale Read only Unimplemented string The language code for the key event, if available; otherwise, the empty string.
ctrlKey Read only boolean true if the control key was down when the event was fired. false otherwise.
shiftKey Read only boolean true if the shift key was down when the event was fired. false otherwise.
altKey Read only boolean true if the alt key was down when the event was fired. false otherwise.
metaKey Read only boolean true if the meta key was down when the event was fired. false otherwise.
