I don't know much about jsp, but I would think this would be proper:

 function sortResults(sortOption) {
    <% if(request.getAttribute("id")!=null){
             String pId = (String)request.getAttribute("id");
       }
    %>
       var proId= '<%=pId%>';
    }

Or this, depending on which part is javascript and which is jsp
function sortResults(sortOption) {
    if(request.getAttribute("id")!=null){
    <%
             String pId = (String)request.getAttribute("id");
    %>
       var proId= '<%=pId%>';
    }
    }
