How to show notification while uploading file

OraDev16Jan 30 2025 — edited Jan 30 2025

Hi All,
I've a table named app_file_name where some filenames are stored. In Page 2, Users can upload excel files. I want to show a notification saying “The file is not registered” if filename being uploaded doesn't match any of the filenames stored in the table app_file_name. I've created the following:

create table app_file_name(
id number primary key,
file_name varchar2(4000),
);

ID FILE_NAME
-------------------------------------
1 A.XLSX
2 B.XLSX
3 C.XLSX

PAGE 2

Function and Global Variable Declaration

function show_notification_success(Msg){
apex.message.showPageSuccess(Msg);
$('#t_Alert_Success').attr('style','background-color: green;');
$('.t-Alert-title').attr('style','color: white;font-weight: bold;');
setTimeout(function() {
$('#t_Alert_Success').fadeOut('slow');
}, 5000);
}

function show_notification_error(Msg){
apex.message.showPageSuccess(Msg);
$('#t_Alert_Success').attr('style','background-color: rgb(235, 52, 116);');
$('.t-Alert-title').attr('style','color: white;font-weight: bold;');
setTimeout(function() {
$('#t_Alert_Success').fadeOut('slow');
}, 5000);
}
