//$('body').on('blur', '.qty, .price', function(e) { 
$('.qty, .price').on('blur', function (e) { 
    debugger; 
    // Get Parent ROW 
    var row = $(this).closest('tr'); 
    var qty = $('.qty', row), 
     pr = $('.price', row), 
     tot = $('.total', row); 
    $('#hdnTot').val(tot); 
    quantity = parseFloat(qty.val()); 
    price = parseFloat(pr.val()); 

    if (!isNaN(quantity) && !isNaN(price)) { 
     tot.text((quantity * price).toFixed(2)); 
    } 
}); 

Answer 1

使用tot.val((quantity * price).toFixed(2));代替tot.text((quantity * price).toFixed(2));設置隱藏字段的值。
