But you can use variable in Javascript, for example:

You can also use Variables with event handlers (since JSF 2.0):

But your loop with c:forEach can cause problems. Be aware that the JSTL tags (everything that begins with c:) are not fully compatible to JSF. If you have luck, then they work as expected. But anyways the slow down the rendering engine, since the page gets processed multiple times by the JSF and JSP rendering engine.

Better use ui:repeat.
