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 |
Whether the event normally bubbles or not |
cancelable Read only |
Boolean |
Whether the event is cancellable or not? |
view Read only |
WindowProxy |
document.defaultView (window of the document) |
detail Read only |
long (float) |

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.
