Element: mouseup event

{{APIRef("UI Events")}}

The mouseup event is fired at an {{domxref("Element")}} when a button on a pointing device (such as a mouse or trackpad) is released while the pointer is located inside it.

mouseup events are the counterpoint to {{domxref("Element.mousedown_event", "mousedown")}} events.

This behavior is different from {{domxref("Element/pointerup_event", "pointerup")}} events. When using a physical mouse, mouseup events fire whenever any button on a mouse is released. pointerup events fire only upon the last button release; previous button releases, while other buttons are held down, don't fire pointerup events.

Syntax

Use the event name in {{domxref("EventTarget/addEventListener", "addEventListener()")}}:

addEventListener("mouseup", (event) => { })

Alternatively, assign to the event handler property of the interface:

onmouseup = (event) => { }

Event type

A {{domxref("MouseEvent")}}. Inherits from {{domxref("UIEvent")}} and {{domxref("Event")}}.
