I have to write an link with an image inside. Instead of explaining, here's the code I have now:
<c:if test="${userSession.loggedUser eq null and company.image != null}">
<a onclick="${rich:component('loginPanel')}.show()">
<img src="/download.do?hash=#{company.image.hash}" />
</a>
</c:if>
<c:if test="${userSession.loggedUser eq null and company.image == null}">
<a onclick="${rich:component('loginPanel')}.show()">
<img src="${request.contextPath}/img/icons/logo_default.jpg" />
</a>
</c:if>
<c:if test="${userSession.loggedUser ne null and company.image != null}">
<a href="company.xhtml?${company.name}">
<img src="/download.do?hash=#{company.image.hash}" />
</a>
</c:if>
<c:if test="#{userSession.loggedUser ne null and company.image == null}">
<a href="company.xhtml?${company.name}">
<img src="${request.contextPath}/img/icons/logo_default.jpg" />
</a>
</c:if>
This code looks awful - there are two exact links with two exact images but combined in all possible combinations. Is there a better way? Is there a way to avoid c:if - it created tables?
Update: Bozho proposes:
You can replace <c:if
and <a
with <h:outputLink rendered="#{..}"
. Apart from that I don't see any other optimization.
But it doesn't work. This does not render correctly:
<a href=>
<h:outputLink rendered="#{..}
<h:outputLink rendered="#{..}
</a>
(the image is outside the anchor)
This does render fine:
<h:outputLink value=>
<h:outputLink rendered="#{..}
<h:outputLink rendered="#{..}
</a>
, but it always adds href and in two of the cases I don't want href when rendered.
