那是我的功能:

 <script> function Calculate()
     {
         var ItemPrice = document.getElementById("price");
         var weight = document.getElementById("weight");
         var SelWeight = weight.options[weight.selectedIndex].value;
         alert(SelWeight);
         var Category = document.getElementById("SelectedCategory");
         var SelCategory = Category.options[Category.selectedIndex].value;
         alert(SelCategory);

     }
    </script>

我想SelCategories.Tax,并SelCategories.Duty把它们添加到权重值和总价格,以显示在标签总..我使用ASP.NET MVC 4,这是我的模型,我想使用

public class CategoriesModel
    {
        public int CategoryID { get; set; }
        public string CategoryName { get; set; }
        public decimal Duty { get; set; }
        public decimal Tax { get; set; }
        public IEnumerable<SelectListItem> CategoriesList { get; set; }
    }
