● <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:
The template element creates code that is inserted into all cards in a single deck. The nested
tags are: go, noop, prev, and refresh.
There are no visual implications for supporting the <onevent> tag.
● <postfield> tag - Use the postfield tag to set a name/value pair that can be transmitted
during a URL request to an origin server, the request’s source. The name attribute sets the
name, which must be a valid WML variable name. The value attribute sets the value.
There are no visual rendering implications with this tag.
