This view helper implements an if/else condition. Check ::convertArgumentValue() to see how boolean arguments are evaluated
Conditions:
As a condition is a boolean value, you can just use a boolean argument. Alternatively, you can write a boolean expression there. Boolean expressions have the following form: XX Comparator YY Comparator is one of: ==, !=, <, <=, >, >= and % The % operator converts the result of the % operation to boolean.
XX and YY can be one of:
a String
<f:if condition="{rank} > 100"> Will be shown if rank is > 100 </f:if> <f:if condition="{rank} % 2"> Will be shown if rank % 2 != 0. </f:if> <f:if condition="{rank} == {k:bar()}"> Checks if rank is equal to the result of the ViewHelper "k:bar" </f:if> <f:if condition="{foo.bar} == 'stringToCompare'"> Will result true if {foo.bar}'s represented value equals 'stringToCompare'. </f:if>
= Examples =
<f:if condition="somecondition"> This is being shown in case the condition matches </f:if>
<output> Everything inside the <f:if> tag is being displayed if the condition evaluates to TRUE. </output>
<f:if condition="somecondition"> <f:then> This is being shown in case the condition matches. </f:then> <f:else> This is being displayed in case the condition evaluates to FALSE. </f:else> </f:if>
<output> Everything inside the "then" tag is displayed if the condition evaluates to TRUE. Otherwise, everything inside the "else"-tag is displayed. </output>
{f:if(condition: someCondition, then: 'condition is met', else: 'condition is not met')}
<output> The value of the "then" attribute is displayed if the condition evaluates to TRUE. Otherwise, everything the value of the "else"-attribute is displayed. </output>
