Event Object
The Event object provides a lot of information about a particular event, including information about target element, key pressed, mouse button pressed, mouse position, etc. Unfortunately, there are very serious browser incompatibilities in this area. Hence only the W3C Event object is discussed in this article.
| Type | Name | Description |
|---|---|---|
| DOMString | type | The name of the event (case-insensitive). |
| EventTarget | target | Used to indicate the EventTarget to which the event was originally dispatched. |
| EventTarget | currentTarget | Used to indicate the EventTarget whose EventListeners are currently being processed. |
| unsigned short | eventPhase | Used to indicate which phase of event flow is currently being evaluated. |
| boolean | bubbles | Used to indicate whether or not an event is a bubbling event. |
| boolean | cancelable | Used to indicate whether or not an event can have its default action prevented. |
| DOMTimeStamp | timeStamp | Used to specify the time (in milliseconds relative to the epoch) at which the event was created. |
| Name | Argument type | Argument name | Description |
|---|---|---|---|
| stopPropagation | To prevent further propagation of an event during event flow. | ||

Famous quotes containing the words event and/or object:
“Don’t you go believing in sayings, Picotee: they are all made by men, for their own advantages. Women who use public proverbs as a guide through events are those who have not ingenuity enough to make private ones as each event occurs.”
—Thomas Hardy (1840–1928)
“The Catholic Church has never really come to terms with women. What I object to is being treated either as Madonnas or Mary Magdalenes.”
—Shirley Williams (b. 1930)
