Relevant to any element that can be clicked on, such as a button, this event occurs when the mouse is clicked on an element that uses it. For some widgets that use this event, using oncommand attribute (which covers clicking) is recommended to avoid excluding keyboard selection. Here are some commonly used properties associated with this event:
This property tells you which mouse button was clicked. Its values are 0 for the left mouse button, 1 for middle button, and 2 for right button.
This property counts how many clicks occur over an element before the mouse is moved. The values for this property start at 1 and increment for every click.
Instead of catching double clicks this way, you can use the ondblclick event.
