当我退出屏幕时，我会被问到：“你要保存吗？”codeigniter

Question

I want to do something like this: If I am viewing a record and edit it or add a new record and then exit that screen, I should be asked, “Do you want to save?”

How can I develop this thing in php? I haven't done this type of development before..

Any suggestions?

use jquery onbeforeunload function it will be execute when page refresh or closing browser tab or closing browser .

 $(window).on('beforeunload', function(){
                  return 'Are you sure you want to leave?';
           });

</div>
