How to use a JavaScript variable in an EL expression

Question

I am trying to archive very simple things but I'm not getting the expected result from the below script. I don't know what im going wrong.

<script>      
        var APP = "APPR";// in properties file APPR = Approved
        var message = "#{props["APP"]}";// JSF EL expression with resourcebundle 
        alert(message)// Want to print "Approved" but its printing ??APP???
</script>

Im using JSF resourcebundle and javascript.

Thanks Napster, I already tried this but im getting error "EL Expression Unbalanced: ... #{props['"+ APP + "']}";" — user1127643, Dec 03 '16 at 17:10
Use single quotes when dealing with Maps and similar expressions. — kolossus, Dec 04 '16 at 05:07

@JasperdeVries no duplicate variable in EL expression. I have only 3 line javascript code. — user1127643, Dec 05 '16 at 11:36
