ASP.NET MVC HtmlHelper类的辅助和扩展方法

官网说明:http://msdn.microsoft.com/en-us/library/system.web.mvc.htmlhelper.aspx

(1)ActionLink  生成一个特定的控制器行为连接

            <%=Html.ActionLink("Edit", "Edit", "Book", new { id = Model.ID }, new { @class = "BookDetail"})%>
            具体说明:

            Edit,为linkText,具体而言就是显示的字符串
            Edit,对应为ActionName;
          Book,为Controller;
          new { id = Model.ID },为生成元素的id定义;
          new { @class = “BookDetail” },则为元素添加了tag要素

(2)AntiForgeryToken 生成一个隐藏的表单字段,可与ValidateAntiForgeryToken属性一起使用以确保Request没有被修改

            具体说明:

                 如果你要保护你的应用程序的多个形式的相互独立,AntiForgeryToken 将生成不同的防伪标志

                  <%= Html.AntiForgeryToken("someArbitraryString") %>

                  [ValidateAntiForgeryToken(Salt="someArbitraryString")]
                 public ViewResult SubmitUpdate()
                 {
                           // ... etc
                  }


(3)AttributeEncode 数据属性编码 :提供了HtmlAttributeEncode功能

                具体说明:

                 <%= Html.AttributeEncode(Url.Action("Login")) %>


(4)DropDownList   基于一对键值对生成DropDownList

               具体说明:

             Html.DropDownList(    string name,    IEnumerable<SelectListItem> selectList,    string optionLabel,    object htmlAttributes)

             name:选择元素的名称,绑定到元素视图的模型属性

             selectList:选项列表,

             optionLabel:类似与“Select …”   可选的默认的标签

             htmlAttributes:可添加的属性

             使用方法
            

 

   List < SelectListItem >  items  =   new  List < SelectListItem > ();
         items.Add( 
new  SelectListItem { Text  =   " Swimming " , Value  =   " 1 "  }); 
         items.Add(
new  SelectListItem { Text  =   " Cycling " , Value  =   " 2 " , Selected  =   true  }); 
         items.Add(
new  SelectListItem { Text  =   " Running " , Value  =   " 3 "  }); 
        ViewData[
" ListItems " =  items;
        List < SelectListItem >  items  =   new  List < SelectListItem > ();
         items.Add( 
new  SelectListItem { Text  =   " Swimming " , Value  =   " 1 "  }); 
         items.Add(
new  SelectListItem { Text  =   " Cycling " , Value  =   " 2 " , Selected  =   true  }); 
         items.Add(
new  SelectListItem { Text  =   " Running " , Value  =   " 3 "  }); 
        ViewData[
" ListItems " =  items;

 

           <%= Html.DropDownList("ListItems") %>

(5)Encode 编码字符串,以防跨站脚本攻击    

   使用方法
            < %=Html.Encode("< script src=\"j . JS\">< div background='javascript:alert('');'/>")%>
    编码结果
             &lt;script src=&quot;j . JS&quot;&gt;&lt;/script&gt;&lt;div background='javascript:alert('');'/&gt;
