This approach will not work. You seem to be confusing/mixing the basic web development concepts of the "server side" and "client side" and to be misunderstanding the role of JSF and EL.
JSF is a server side language which runs on the webserver upon a HTTP request and produces HTML/CSS/JS code which get returned with the HTTP response. All EL expressions in form of ${}
and #{}
will be executed in the server side during generating the HTML output. JavaScript is a client side language which runs on the webbrowser and works on the HTML DOM tree. The HTML onclick attribute should specify a JavaScript function which will be executed in the client side on the particular HTML DOM event.
In order to invoke a JSF managed bean method, you need the action
or *listener
attribute. JSF provides components to generate the desired HTML and specify the desired ajax actions which would change the server side state. An <input type="image">
can be generated using a <h:commandButton image>
. A bean method can be invoked by the action
attribute of that component. That component can be ajaxified by embedding the <f:ajax>
tag.
So, the following should do it for you:
<h:form>
<div class="sidebarOptions">
<h:commandButton image="images/homeButton.jpg" action="#{home.setRendered(1)}">
<f:ajax execute="@this" render=":sidebar" />
</h:commandButton>
</div>
<div class="sidebarOptions">
<h:commandButton image="images/memberButton.jpg" action="#{home.setRendered(2)}">
<f:ajax execute="@this" render=":sidebar" />
</h:commandButton>
</div>
</h:form>
<!-- The below is just a guess of what you're really trying to achieve. -->
<h:panelGroup id="sidebar" layout="block">
<h:panelGroup rendered="#{home.rendered eq 1}">
Home
</h:panelGroup>
<h:panelGroup rendered="#{home.rendered eq 2}">
Member
</h:panelGroup>
</h:panelGroup>
