Using jQuery and JSON Action methods in MVC

1. jQuery + JSON Action Methods = Cool
   It is easy to return a JSON object instead of a view.

   public JsonResult Create(string CategoryName)
   {
       var category = new Models.Category();
       category.Name = CategoryName;
       category.URLName = CategoryName.ToLower().Replace(" ", "-");
       categoryRepository.Add(category);
       categoryRepository.Save();
   
       return Json(category);
   }

   <script class="str" type="<span">
   "text/javascript" language="javascript">
       $("#CreateNewCategory").click(function() {
           $.getJSON("/category/create/",
                     { "CategoryName": $("#NewCategoryName").val() },
                     CategoryAdded);
                 });
   
                 function CategoryAdded(category) {
                     $("#CategoryList").append("
    + category.URLName + "/cat\">" + category.Name + "
   ");
                 }
   </script>
