本文实例为大家分享了MVC+jQuery.Ajax异步实现增删改查和分页的具体代码，供大家参考，具体内容如下

1、Model层代码

using System;
using System.Data;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Collections.Generic;
using MvcExamples;
using System.Web.Mvc;

namespace MvcExamples.Web.Models
{
 public class StudentModels
 {
 /// <summary>
 /// 获取学生信息列表
 /// </summary>
 public List<MvcExamples.Model.Student> StudentList { get; set; }
 /// <summary>
 /// 获取教工信息列表
 /// </summary>
 public List<MvcExamples.Model.Teacher> TeacherList { get; set; }
 /// <summary>
 /// 获取学生信息列表(分页)
 /// </summary>
 public PagedList<MvcExamples.Model.Student> GetStudentList { get; set; }
 }
}

2、View层代码

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcExamples.Web.Models.StudentModels>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
 Index
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="HeadContent" runat="server">

 <script src="/UploadFiles/2021-04-02/jquery-1.4.2.min.js">

3、Controller层代码


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Mvc.Ajax;

namespace MvcExamples.Web.Controllers
{
 public class StudentController : Controller
 {
 //
 // GET: /Student/

 MvcExamples.BLL.Student _Student = new MvcExamples.BLL.Student();
 MvcExamples.BLL.Teacher _Teacher = new MvcExamples.BLL.Teacher();
 /// <summary>
 /// 演示
 /// </summary>
 /// <param name="pi"></param>
 /// <param name="sclass"></param>
 /// <returns></returns>
 public ActionResult Index(int"95031" : sclass;
  MvcExamples.Web.Models.StudentModels _StudentModels = new MvcExamples.Web.Models.StudentModels();
  _StudentModels.StudentList = _Student.GetModelList("sclass=" + sClass);
  _StudentModels.TeacherList = _Teacher.GetModelList("tsex='男'");
  _StudentModels.GetStudentList = new PagedList<MvcExamples.Model.Student>(_Student.GetModelList("sclass=" + sClass).AsQueryable(), PageIndex, PageSize);
  return View(_StudentModels);//返回一个Model
 }
 /// <summary>
 /// 修改学生信息
 /// </summary>
 /// <param name="no"></param>
 /// <param name="name"></param>
 /// <param name="sex"></param>
 /// <param name="birsthday"></param>
 /// <param name="sclass"></param>
 /// <returns></returns>
 public ActionResult UpdateStudent(string no, string name, string sex, string birsthday, string sclass)
 {
  MvcExamples.Model.Student _student = new MvcExamples.Model.Student();
  _student.sno = no;
  _student.sname = name;
  _student.ssex = sex;
  _student.sbirthday = Convert.ToDateTime(birsthday);
  _student.sclass = sclass;

  _Student.Update(_student);  

  JsonResult json = new JsonResult();
  json.Data = new
  {
  result = "true"
  };
  return json;
 }
 /// <summary>
 /// 删除学生信息
 /// </summary>
 /// <param name="no"></param>
 /// <returns></returns>
 public ActionResult DeleteStudent(string no)
 {
  bool IsDelete= _Student.Delete(no);
  JsonResult json = new JsonResult();
  return json;
  if (IsDelete)
  {
  json.Data = new
  {
   result = "true"
  };
  }
  else
  {
  json.Data = new
  {
   result ="false"
  };
  }
  return json;
 }
 /// <summary>
 /// 添加学生信息
 /// </summary>
 /// <param name="no"></param>
 /// <param name="name"></param>
 /// <param name="sex"></param>
 /// <param name="birsthday"></param>
 /// <param name="sclass"></param>
 /// <returns></returns>
 public ActionResult AddStudent(string no, string name, string sex, string birsthday, string sclass)
 {
  MvcExamples.Model.Student _student = new MvcExamples.Model.Student();
  _student.sno = no;
  _student.sname = name;
  _student.ssex = sex;
  _student.sbirthday = Convert.ToDateTime(birsthday);
  _student.sclass = sclass;

  _Student.Add(_student);

  JsonResult json = new JsonResult();
  json.Data = new
  {
  result = "true"
  };
  return json;
 }

 /// <summary>
 /// 提供弹出窗口的数据
 /// </summary>
 /// <param name="id"></param>
 /// <returns></returns>
 public ActionResult WindowData(int id)
 {
  JsonResult json = new JsonResult();
  //这里给json数据(这里只是演示，下面数据是模拟的)
  json.Data = new
  {
  name = "张三",
  sex = "男"
  };
  return json;
 }

 }
}



4、两个分页辅助类PagedList和MikePagerHtmlExtensions
PagedList辅助类


using System;
using System.Data;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Collections.Generic;
using System.Collections.Specialized;

namespace System.Web.Mvc
{
 public interface IPagedList
 {
 int TotalPage //总页数
 {
  get;
 }

 int TotalCount
 {
  get;
  set;
 }

 int PageIndex
 {
  get;
  set;
 }

 int PageSize
 {
  get;
  set;
 }

 bool IsPreviousPage
 {
  get;
 }

 bool IsNextPage
 {
  get;
 }
 }

 public class PagedList<T> : List<T>, IPagedList
 {
 public PagedList(IQueryable<T> source, int"color: #800000">MikePagerHtmlExtensions辅助类


using System;
using System.Data;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Web.Mvc;
using System.Web.Routing;
using System.Text;

namespace System.Web.Mvc
{
 public static class MikePagerHtmlExtensions
 {
 
 #region MikePager 分页控件

 public static string MikePager<T>(this HtmlHelper html, PagedList<T> data)
 {
  string actioinName = html.ViewContext.RouteData.GetRequiredString("action");
  return MikePager<T>(html, data, actioinName);
 }

 public static string MikePager<T>(this HtmlHelper html, PagedList<T> data, object values)
 {
  string actioinName = html.ViewContext.RouteData.GetRequiredString("action");
  return MikePager<T>(html, data, actioinName, values);
 }

 public static string MikePager<T>(this HtmlHelper html, PagedList<T> data, string action)

 {
  string controllerName = html.ViewContext.RouteData.GetRequiredString("controller");
  return MikePager<T>(html, data, action, controllerName, values);
 }

 public static string MikePager<T>(this HtmlHelper html, PagedList<T> data, string action, string controller, object values)
 {
  return MikePager<T>(html, data, action, controller, new RouteValueDictionary(values));
 }

 public static string MikePager<T>(this HtmlHelper html, PagedList<T> data, RouteValueDictionary values)
 {
  string actioinName = html.ViewContext.RouteData.GetRequiredString("action");
  return MikePager<T>(html, data, actioinName, values);
 }

 public static string MikePager<T>(this HtmlHelper html, PagedList<T> data, string action, RouteValueDictionary values)
 {
  string controllerName = html.ViewContext.RouteData.GetRequiredString("controller");
  return MikePager<T>(html, data, action, controllerName, values);
 }

 public static string MikePager<T>(this HtmlHelper html, PagedList<T> data, string action, string controller, RouteValueDictionary valuedic)
 {
  int start = (data.PageIndex - 5) >= 1 "<div class=\"mike_mvc_pager\">");

  if (data.IsPreviousPage)
  {
  vs["pi"] = 1;
  builder.Append(Html.LinkExtensions.ActionLink(html, "首页", action, controller, vs, null));
  builder.Append("&nbsp;");
  vs["pi"] = data.PageIndex - 1;
  builder.Append(Html.LinkExtensions.ActionLink(html, "上一页", action, controller, vs, null));
  builder.Append("&nbsp;");

  }

  for (int i = start; i <= end; i++) //前后各显示5个数字页码
  {
  vs["pi"] = i;
  if (i == data.PageIndex)
  {
   builder.Append("<font class='thispagethis'>" + i.ToString() + "</font>&nbsp;");
  }
  else
  {
   builder.Append("&nbsp;");

   builder.Append(Html.LinkExtensions.ActionLink(html, i.ToString(), action, controller, vs, null));
  }
  }

  if (data.IsNextPage)
  {
  builder.Append("&nbsp;");

  vs["pi"] = data.PageIndex + 1;
  builder.Append(Html.LinkExtensions.ActionLink(html, "下一页", action, controller, vs, null));
  builder.Append("&nbsp;");


  vs["pi"] = data.TotalPage;
  builder.Append(Html.LinkExtensions.ActionLink(html, "末页", action, controller, vs, null));


  }
  builder.Append("&nbsp;每页" + data.PageSize + "条/共" + data.TotalCount + "条 第" + data.PageIndex + "页/共" + data.TotalPage + "页 </div>");
  return builder.ToString();
 }
 #endregion
 }
}
