GlobalEventHandlers.onmouseup
The onmouseup
property of the
GlobalEventHandlers
mixin is an event handler that
processes mouseup
events.
The mouseup
event fires when the user releases the mouse button.
Note: The opposite of onmouseup
is
onmousedown
.
Syntax
target.onmouseup = functionRef;
Value
functionRef
is a function name or a function
expression. The function receives a MouseEvent
object as its sole
argument.
Example
In this example, a piece of "toast" hides when you click down with the mouse, and
reappears when you release. It uses the onmousedown
and onmouseup
event handlers.
