首先使用Asp.Net MVC可以不使用Html Helper,不过使用了Html Helper可以节约很多时间的O(∩_∩)O~

一、标准Html Helper

.ActionLink

创建一个链接,但现在还不能创建一个带图片的链接

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %><asp:ContentID="indexContent"ContentPlaceHolderID="MainContent"runat="server"><p>To learn more about this website, click the following link:<%= Html.ActionLink("About this Website","About")%></p></asp:Content>
"Aboud this Website”显示的内容,"About” Action的名字
生成的Html如下:
<ahref="/Home/About">About this Website</a>
ActionLink可以添加接受很多参数

· linkText – 链接上的文字

· actionName – 链接目标的action名字

· routeValues – 通向action的route值

· controllerName – controller名字

· htmlAttributes – 链接的html属性

· protocol – 链接协议 (比如:https)

· hostname – 链接的Host名字 (比如:www.MyWebsite.com)

· fragment – 这个还没弄的太明白╮(╯▽╰)╭

如果想添加个图片链接,使用Url.Action:

<ahref="<%= Url.Action("Delete") %>"><imgsrc="http://www.cnblogs.com/Content/Delete.png"alt="Delete"style="border:0px"/></a>
 
Html Helper还可以生成很多Html控件:

· BeginForm()

· CheckBox()

· DropDownList()

· EndForm()

· Hidden()

· ListBox()

· Password()

· RadioButton()

· TextArea()

· TextBox()

 

基本上看名字就知道了,看例子:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcApplication1.Models.Customer>" %><asp:ContentID="Content2"ContentPlaceHolderID="MainContent"runat="server"><%= Html.ValidationSummary("Create was unsuccessful. Please correct the errors and try again.")%><%using(Html.BeginForm()) {%><fieldset><legend>Register</legend><p><labelfor="FirstName">First Name:</label><%= Html.TextBox("FirstName")%><%= Html.ValidationMessage("FirstName","*")%></p><p><labelfor="LastName">Last Name:</label><%= Html.TextBox("LastName")%><%= Html.ValidationMessage("LastName","*")%></p><p><labelfor="Password">Password:</label><%= Html.Password("Password")%><%= Html.ValidationMessage("Password","*")%></p><p><labelfor="Password">Confirm Password:</label><%= Html.Password("ConfirmPassword")%><%= Html.ValidationMessage("ConfirmPassword","*")%></p><p><labelfor="Profile">Profile:</label><%= Html.TextArea("Profile",new{cols=60, rows=10})%></p><p><%= Html.CheckBox("ReceiveNewsletter")%><labelfor="ReceiveNewsletter"style="display:inline">Receive Newsletter?</label></p><p><inputtype="submit"value="Register"/></p></fieldset><%}%></asp:Content>

其中Html.BeginForm()和EndForm()要单独说一下:默认情况下,它会指向和自己相同的action,但也会接受不同参数改变指向的action:

· routeValues -- 如上

· actionName – 如上

· controllerName – 如上

· method – 只能使用POST和GET,必须使用javascript

· htmlAttributes – 如上

 

.Encode(),这个就是替换<为&lt; >为&gt;等等

.AntiForgeryToken这个是为了抵御跨域攻击的。

<%= Html.AntiForgeryToken()%>

<inputname="__RequestVerificationToken"type="hidden"value="6tbg3PWU9oAD3bhw6jZwxrYRyWPhKede87K/PFgaw     6MI3huvHgpjlCcPzDzrTkn8"/>
helper会创建一个cookie和这个隐藏域的值相比较
在Controller中如下写代码就可以了:
usingSystem.Web.Mvc;namespaceMvcApplication1.Controllers  {publicclassBankController : Controller      {//// GET: /Bank/WithdrawpublicActionResult Withdraw()          {returnView();          }//// POST: /Bank/Withdraw[AcceptVerbs(HttpVerbs.Post)]          [ValidateAntiForgeryToken]publicActionResult Withdraw(decimalamount)          {// Perform. withdrawalreturnView();          }        }  }

创建自己的HTML Helpers

usingSystem;usingSystem.Web.Mvc;namespaceHelpers  {publicstaticclassSubmitButtonHelper      {/// <summary>/// Renders an HTML form. submit button/// </summary>publicstaticstringSubmitButton(thisHtmlHelper helper,stringbuttonText)          {returnString.Format("<input type=\"submit\" value=\"{0}\" />", buttonText);          }        }  }

这样就名了吧,创建一个submit.(*^__^*)

这样可以创建很复杂的Html格式的。发挥想象
