How to specify the 5 apex items on my javascript code at oracle apex

Please see picture on the link. How do I code 5 apex page items in a javascript using if else condition. Initially, what I am doing is i am trying to hide regions which will have empty page items and that depends on the sql query results. please help. thank you.

Here is my code:

if (apex.item("P82_SOLN_4" ).isEmpty()) {

$x_Hide("soln4");

} else {

$x_Show("soln4");

}
