Control structures enable you to dynamically
hide or show certain parts of a heitml
page. You can also show certain parts repeatedly.
<if SrvTime < 110000000>
Good Morning, you are guest number
<counter name="morning"> this morning.
shows the text "Good Morning..." when
SrvTime < 110000000
(i.e. before 11 in the morning), otherwise it shows
Note that the "morning"-counter is on the page
only before 11 am. The <if> tag works on all
aspects of a component, so a component
isn't just hidden; it won't perform
any function unless the condition is true.
Therefore, in our example, the counter counts only in the morning.
The content shows up only if show is set to true. Cond is useful
especially when a dynamic condition is used, which is possible
when programming .
|Show||Checkbox ||Can be true or false. |
|Negate||Checkbox ||Negates the condition. |
