Question

I have an application with a client-side image map with multiple sections defined. I need to call a method in the Managed Bean from the <area> onclick attribute.

This doesn’t work:

<area id="ReviewPerson" shape="rect" coords="3, 21, 164, 37" href="#" 
    onclick="#{personBean.method}" alt="Review Person" id="reviewPersonArea"
    title="Review Person" />

Since my hands are tied on the image map (unfortunately), how can I call a managed bean method from within the <area> tag?

Answer 1

You have a few options. If you are using JSF 2.0 you can build a composite component around these area tags.

The easiest way however would be to invoke a hidden JSF input button.

<h:commandButton id="hdnBtn" actionListener="#{personBean.method}" style="display: none;" />

This will render as an input HTML element on the page that you can access from Javascript and invoke its click event.

onclick="jQuery('#form:hdnBtn').click();"
