Event properties used

target
Indicates the object to which the event was originally sent.

layerX, layerY,

which
Represents 1 for a left-mouse-button up and 3 for a right-mouse-button up.

Description

If onMouseUp returns false, the default action is canceled. For example, if onMouseUp returns false over an armed link, the link is not triggered. Also, if MouseUp occurs over an unarmed link (possibly due to onMouseDown returning false), the link is not triggered.

Note

Arming is caused by a MouseDown over a link. When a link is armed it changes color to represent its new state.
