The representation of if-elseif-else in EL using JSF

Question

The following JSF code contains two separate . Let\'s look at it.

<         


        

Answer 1

One possible solution is:

<h:panelGroup rendered="#{bean.row == 10}">
    <div class="text-success">
        <h:outputText value="#{bean.row}"/>
    </div>
</h:panelGroup>

Answer 2

You can use "ELSE IF" using conditional operator in expression language as below:

 <p:outputLabel value="#{transaction.status.equals('PNDNG')?'Pending':
                                     transaction.status.equals('RJCTD')?'Rejected':
                                     transaction.status.equals('CNFRMD')?'Confirmed':
                                     transaction.status.equals('PSTD')?'Posted':''}"/>

Answer 3

You can use EL if you want to work as IF:

<h:outputLabel value="#{row==10? '10' : '15'}"/>

Changing styles or classes:

style="#{test eq testMB.test? 'font-weight:bold' : 'font-weight:normal'}"

class="#{test eq testMB.test? 'divRred' : 'divGreen'}"

Answer 4

The following code the easiest way:

 <h:outputLabel value="value = 10" rendered="#{row == 10}" /> 
 <h:outputLabel value="value = 15" rendered="#{row == 15}" /> 
 <h:outputLabel value="value xyz" rendered="#{row != 15 and row != 10}" />
