APEX

Hello,

Can anyone please help me out with this issue. I wanted to display an javascript alert message from within a pl/sql block for an update button. Below is sample code which i am using. P1_ITEM is my hidden item on the report.


begin
if :P1_ITEM IS NOT NULL then
HTP.p ('<script type="text/javascript">');
HTP.p ('alert(''Please complete the item which is already assigned to you!'');');
HTP.p ('</script>');
end if;
end;

and I have made this code to be executed conditionally when request = Expression1
Expression1: SUBMIT

The thing is I am not able to display an alert message when the update button is clicked.

Can anyone please help me with this one.

Thanks,
Orton
