target 읽기 전용 |
EventTarget (DOM element) | Focused element processing the key event, root element if no suitable input element focused. |
char 읽기 전용 |
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 읽기 전용 |
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 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 읽기 전용 |
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 읽기 전용 |
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
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 읽기 전용 |
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

repeat 읽기 전용 |
boolean |
true if a key has been depressed long enough to trigger key
repetition, otherwise false.

preventDefault() of keydown event
Starting with Gecko 25, a call of preventDefault() of keydown event prevents to dispatch following keypress event. This is valid behavior for D3E spec and the other major web browsers behave so. On the other hand, Gecko 24 or earlier dispatched keypress event even if preventDefault() of preceding keydown event is called. Although the keypress event's defaultPrevented attribute was true in this case.
