QUESTION_TEXT Explain the four task elements of WML.
WML allows us to specify tasks that can be performed when a certain
events occurs, such as navigating to a specified card or deck. WML
includes four task elements. The four tasks are go, prev, noop, refresh.
Tasks are bound to do an event. An anchor element may contain a go,
prev, or refresh task.
1.Go task: The ‘go’ element declares a go task, indication navigation to
an URL. If the URL names a WML card or deck, it is displayed. A
go executes a push operation on the history.
The attributes of the go element are :Href=href, Sendreferer=boolean, Method= (post|get), Acceptcharset=CDATA, Id,Class.
The go element may contain one more postfield element. These elements
specify information to be submitted to the origin server during the request.
SCHEME OF
EVALUATION
2.Prev task: The prev element declares a prev task, indicating
navigation to the previous URI in the history stack. A prev
performs a pop operation on the history stack and removes the
current URI from the history stack. If there is no previous URI in
the history, stack, the prev element has no effect.
Attribut- Id, Class
3.
Refresh task: The refresh element declares refresh task,
indicating an update of the specified card variables. Side effects of the
states changes that are visible to the user occur during the processing
of the refresh task. A refresh and its side effects must occur even if the
elements have no setvar elements given that context may change by
other names. The attribute of the refresh elements are:Id, Class
3.Noop task: The noop element specifies that nothings should be done,
that is, “no operation”. This element is useful for overriding decklevel do elements.
The attributes of the noop element are
Id, Class
WML allows programmer to specify tasks that can be performed when
a certain event occurs, such as navigating to a specified card or deck.
