Excerpted from w3school:http://www.w3school.com.cn/htmldom/dom_events.asp

OnMouseDown, onmouseup, and onclick events are the entire process of mouse clicks.

First, when a mouse button is clicked, the OnMouseDown event is triggered, and then, when the mouse button is released, the OnMouseUp event is triggered and, finally, the onclick event is triggered when the mouse click is complete.
