try this :
window.previousHead=null;
   $('select[id^=no]').focus(function(e){
       previousHead = $(this).val(); 
alert(previousHead );
       
    });

Open in new window

or this :
var previousHead ;
   $('select[id^=no]').mouseover(function(e){
       previousHead = $(this).val(); 
alert(previousHead );
       
    });

Open in new window

and finally try this if you load with ajax :
var previousHead ;
   $(document).on("focus", 'select[id^=no]', function(e){
       previousHead = $(this).val(); 
alert(previousHead );
       
    });

Open in new window
