Event type constants (Constant/static)

Netscape defines a set of constants that represent event types.

Netscape provides some static properties of the Event object class that define mask values for event types. These can then be combined with a bitwise OR operator to build a mask that can be applied with the captureEvents() and releaseEvents() methods that are supported by Window, Document and Layer objects.

Here is a list of the available event type constants:

2^0MOUSEDOWNThe mouse button was pressed while the pointer was over the element.
2^1MOUSEUPThe mouse button was released while the pointer was within the extent region of the element.
