Event Elements
C-11
■ <onevent> tag - The onevent tag serves as a container for code that you wish to be 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. The intrinsic event must be specified
using the mandatory type attribute.
For example, when a user presses the BACK softkey, instead of being routed to the previous
screen, the user will be directed to another specified page because this tag carries out a
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 as follows, go, noop, prev, and refresh.
There are no visual implications for supporting the <onevent> tag.
■ <postfield> tag - The postfield tag is used to set a name/value pair that can be transmitted to
an origin server (source of the request) during a URL request. The name is set by the name
attribute and must be a valid WML variable name. The value is set by the value attribute.
There are no visual rendering implications with this tag.
