Поскольку вы уже используете JQuery вы можете написать функцию, чтобы сделать это. –

function assignOfficer() { 
    var recommendedOfficer; 
    var sanctionOfficer; 
    var numOfDays = $('#No_of_days').val(); 
    //Your various condition to assign officer in 'recommendedOfficer' and 'sanctionOfficer' 
    $('#Recommended_Officer').val(recommendedOfficer); 
    $('#Sanction_Officer').val(sanctionOfficer); 
}
