WML Tags and Attributes
Issue 1 April 2005 161
<onevent> tag - The onevent tag serves as a container for code that you want executed
automatically when one of the four intrinsic events occurs. The onevent element is said to
bind (associate) the tasks (code) to the event for the element. You must specify the
intrinsic event using the mandatory type attribute.
For example, when a user presses the BACK softkey, instead of being routed to the
previous screen, the user is directed to another specified page because this tag carries out
an onevent backward event.
The intrinsic events are:
