Calling Javascript function from PL/SQL Page Process

Question

Hi All,
So far I have seen many threads that answered the question: Calling a PL/SQL from a Javascript function. I would like to know if it's posiible to do the reverse process as follows:
DECLARE
   v_name APPLICANTS.NAME%Type;
   v_surname APPLICANTS.SURNAME%Type;
   v_idNumber APPLICANTS.ID_NUMBER%Type;
BEGIN
   select name, surname
   into v_name, v_surname
   from APPLICANTS
   where id_number = :P2_ID_NUMBER;
   //Javascript function call Syntax is what i'd like find out
   onchange="javascript:show_Name(v_name,v_surname);";
EXCEPTION
   WHEN OTHERS
   THEN
   onchange="javascript:show_Exception(v_name,v_surname);";
END;& Javascript function to shiow applicant's details is:
function show_Name(item1,item2){
   alert('Applicant's Name is: '  + item1 + ' & Surname is: ' + item2);
}THANK YOU!

Hi Dinesh, Thanks for the response!
I've also tried doing the following without success:
DECLARE
   v_name APPLICANTS.NAME%Type;
   v_surname APPLICANTS.SURNAME%Type;
   v_idNumber APPLICANTS.ID_NUMBER%Type;
BEGIN
   select name, surname
   into v_name, v_surname
   from APPLICANTS
   where id_number = :P2_ID_NUMBER;
   htp.p('<script type="text/javascript">');
   htp.p('
            alert('Applicant's Name is: '  + v_name + ' & Surname is: ' + v_surname);
   htp.p('</script>');
EXCEPTION
   WHEN OTHERS
   THEN
   htp.p('<script type="text/javascript">');
   htp.p('
         alert('Exception.');
   htp.p('</script>');;
END;Do you know why this is not working?
