For many of the conditional tags, a second tag is included for testing whether the condition is false. If the condition is false, the tag’s body is included.
Often, it is necessary to include HTML if a condition is true and to include different HTML if the condition is false. This is done by adding a conditional tag for testing if the condition is true, and then adding the corresponding tag for testing if the condition is false.
The following selects one style for an anchor if the current node is the launched node, and selects a different style if it is not the launched node:
<nav:ifNavNodeEqualsCurrentlyLaunchedNavNode>
<nav:navNodeAnchor
navigationMethod="byURL"
urlParameters="<%=urlParameters%>"
anchorAttributes="class='lightDTNTextSelected'"/>
</nav:ifNavNodeEqualsCurrentlyLaunchedNavNode>
<nav:ifNotNavNodeEqualsCurrentlyLaunchedNavNode>
<nav:navNodeAnchor
navigationMethod="byURL"
urlParameters="<%=urlParameters%>"
anchorAttributes="class='lightDTNText'"/>
</nav:ifNotNavNodeEqualsCurrentlyLaunchedNavNode>
The tags for checking if a condition is false are the same as the tags for checking if the condition is true, except that they start with ifNot instead of if.
The following is a list of tags for checking if a condition is false.
