| To invoke |
Click the left mouse button twice in rapid succession over an object. The two clicks must occur within the time limit specified by the double-click speed setting of the user's system. |
| Default action |
Initiates any action that is associated with the event. |
The order of events leading to the ondblclick event is onmousedown, onmouseup, onclick, onmouseup, and then ondblclick. Actions associated with any of these events will be executed when the ondblclick event fires.
While event handlers in the Document Object Model do not receive parameters directly, the handler can query the event object for data.
