How to show alert message based on server response in JSF

Question

I have the following link in one of my JSPs. When an user clicks on that link I'm calling an action in my backing bean. I need to show a JavaScript alert message based on the response of that action.

<h:commandLink onclick="setSelectedClientAndFund();" id="next"
  action="#{fyeSelection.getFYEReportHome}">
    <h:graphicImage value="../images/NextBT.png"></h:graphicImage>
    <a4j:loadScript src="alert('hello');"></a4j:loadScript>
</h:commandLink>

How can I achieve this?

Answer 1

Just render the script conditionally.

<h:outputText value="<script>alert('hello');</script>" escape="false" rendered="#{bean.show}" />
