First, ASP. net mvc can be usedHtml HelperHowever, using HTML helper can save a lot of time for O (hour _ hour) O ~

I. Standard HTML helper

.Actionlink

Create a link, but you cannot create a link with an image

<%@ 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>

The content displayed in "Aboud this Website" and the name of "about" Action

The generated HTML is as follows:

<ahref="/Home/About">About this Website</a>

Actionlink can be added to accept many parameters

· Linktext-text on the Link

· Actionname-action name of The Link Target

· Routevalues-route value leading to action

· Controllername-controller name

· Htmlattributes-link HTML attributes

· Protocol-connection protocol (for example, https)

· Hostname-Host Name of The Link (for example, www.mywebsite.com)

· Fragment-this is not too explicit (too explicit) yet

To add an image link, use URL. Action:

<ahref="<%= Url.Action("Delete") %>"></a>

HTML helper can also generate many HTML controls:

· Beginform ()

· Checkbox ()

· Dropdownlist ()

· Endform ()

· Hidden ()

· ListBox ()

· Password ()

· Radiobutton ()

· Textarea ()

· Textbox ()

 

You can see the name. For example:

<%@ 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>

Here, HTML. beginform () and endform () should be said separately: by default, it will point to the same action as itself, but it will also accept the action to which different parameters change:

· Routevalues -- As shown above

· Actionname-as shown above

· Controllername-as shown above

· Method-only post and get can be used, and JavaScript must be used

· Htmlattributes-above

 

. Encode (),Replace <with & lt;> with & gt; and so on.

.AntiforgerytokenThis is to defend against cross-origin attacks.

<%= Html.AntiForgeryToken()%>

<inputname="__RequestVerificationToken"type="hidden"value="6tbg3PWU9oAD3bhw6jZwxrYRyWPhKede87K/PFgaw     6MI3huvHgpjlCcPzDzrTkn8"/>

Helper will create a cookie and compare it with the value of this hidden domain

Write the following in controller:CodeYou can:

usingSystem.Web.Mvc;namespaceMvcApplication1.Controllers  {publicclassBankController : Controller      {//// GET: /Bank/WithdrawpublicActionResult Withdraw()          {returnView();          }//// POST: /Bank/Withdraw[AcceptVerbs(HttpVerbs.Post)]          [ValidateAntiForgeryToken]publicActionResult Withdraw(decimalamount)          {// Perform. withdrawalreturnView();          }        }  }

Create your own 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);          }        }  }

Create a submit. (* ^__ ^ *)

This allows you to create complex HTML formats. Give full play to your imagination.
