I receive lang param from request

Answer 1

You would assign your JSTL parameter to a JavaScript variable:

<script type="text/javascript">
var lang = "${lang}";  // When JSP gets processed, this becomes var lang = "EN", etc.

$("#"+lang).show();    // Assumes you have a div id="EN" or whatever.
</script>
