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="http://www.cnblogs.com/Scripts/jquery-1.4.2.min.js" type="text/javascript"></script> <script src="http://www.cnblogs.com/Scripts/My97DatePicker/WdatePicker.js" type="text/javascript"></script> <script src="http://www.cnblogs.com/Scripts/windwUi/jquery-ui-1.8.1.min.js" type="text/javascript"></script> <link href="http://www.cnblogs.com/Scripts/windwUi/jquery-ui-1.8.1.custom.css" rel="stylesheet" type="text/css" /> <script type="text/javascript"> $(function(){   //添加学生信息  $('#a_add').click(function(){   $('#window').dialog({      title: "添加学生信息",     width: 300,     height: 200,     modal: true,     buttons: {       "取消": function() {       $(this).dialog("close");

      var sclass=$('#sclass').val();       $.ajax({       type:'post',       url:'/Student/AddStudent',//路径为添加方法       data:'no='+sno+'&name='+sname+'&sex='+ssex+'&birsthday='+sbirsthday+'&sclass='+sclass,//参数的个数和名字要和方法的名字保持一致       success:function(json)//返回的是Json类型的        {         $('#window').dialog("close");          //判断是否成功         if(json.result=="true")         {          $('#btn_close').click();          alert('恭喜你，修改成功！');          }else{          alert('抱歉，修改失败！');         }        }       });      }      }     });  })    //删除学生信息  $('.a_delete').click(function(){   //确认是否删除   if(confirm("是否删除此条信息？"))   {    $.ajax({     type:'post',     url:'/Student/DeleteStudent',     data:'no='+$(this).attr("sno"),//获取当前对象的属性(自定义属性)sno的值，用自定义属性保存相应需要的数据     sucess:function(json)      {       if(json.result=="true")       {        alert("恭喜你，已成功删除！");       }else       {        alert("抱歉，删除失败！");       }      }    })   }  })   //修改学生信息  $('.a_update').click(function(){   var student=$(this);   $("#sno").attr("value",student.attr("sno"));   $("#sname").attr("value",student.attr("sname"));   $("#ssex").attr("value",student.attr("ssex"));   $("#sbirthday").attr("value",student.attr("sbirthday"));   $("#sclass").attr("value",student.attr("sclass"));      $('#window').dialog({     title: "修改学生信息",    width: 300,    height: 200,    modal: true,    buttons: {      "取消": function() {      $(this).dialog("close");      },      "修改": function() {       var sno=$('#sno').val();      var sname=$('#sname').val();      var ssex=$('#ssex').val();      var sbirsthday=$('#sbirthday').val();      var sclass=$('#sclass').val();      $.ajax({      type:'post',      url:'/Student/UpdateStudent',      data:'no='+sno+'&name='+sname+'&sex='+ssex+'&birsthday='+sbirsthday+'&sclass='+sclass,      success:function(json)       {        $('#window').dialog("close");         if(json.result=="true")        {         $('#btn_close').click();         alert('恭喜你，修改成功！');         }else{         alert('抱歉，修改失败！');        }       }      });     }     }     });    });   }) </script></asp:Content><asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>  MVC 演示</h2> <table>  <thead>   <tr>    <td>     学生表    </td>   </tr>   <tr>    <td>     学号    </td>    <td>     姓名    </td>    <td>     性别    </td>    <td>     生日    </td>    <td>     班级    </td>    <td>     操作    </td>   </tr>  </thead>  <tbody>   <%foreach (MvcExamples.Model.Student student in Model.GetStudentList)    {%>   <tr>    <td>     <%=student.sno %>    </td>    <td>     <%=student.sname %>    </td>    <td>     <%=student.ssex %>    </td>    <td>     <%=student.sbirthday %>    </td>    <td>     <%=student.sclass %>    </td>    <td>    <a href="javascript:void(0);" class="a_update" sno="<%=student.sno %>" sname="<%=student.sname %>" ssex="<%=student.ssex %>"      sbirthday="<%=student.sbirthday %>" sclass="<%=student.sclass %>">修改</a>            <a href="javascript:void(0);" class="a_delete" sno="<%=student.sno %>">删除</a>    </td>   </tr>   <% } %>  </tbody>  <tfoot>   <tr>    <td>     全选    </td>    <td colspan="5" style="text-align: right;">     <a href="javascript:void(0);" id="a_add">添加</a>    </td>   </tr>  </tfoot> </table> <%=Html.MikePager(Model.GetStudentList)%> <br /> <table>  <thead>   <tr>    <td>     学生表    </td>   </tr>   <tr>    <td>     学号    </td>    <td>     姓名    </td>    <td>     性别    </td>    <td>     生日    </td>    <td>     班级    </td>   </tr>  </thead>  <tbody>   <%foreach (MvcExamples.Model.Student student in Model.StudentList)    {%>   <tr>    <td>     <%=student.sno %>    </td>    <td>     <%=student.sname %>    </td>    <td>     <%=student.ssex %>    </td>    <td>     <%=student.sbirthday %>    </td>    <td>     <%=student.sclass %>    </td>   </tr>   <% } %>  </tbody> </table> <br /> <table>  <thead>   <tr>    <td>     老师表    </td>   </tr>   <tr>    <td>     编号    </td>    <td>     姓名    </td>    <td>     性别    </td>    <td>     生日    </td>    <td>     职称    </td>    <td>     所在部门    </td>   </tr>  </thead>  <tbody>   <%foreach (MvcExamples.Model.Teacher teacher in Model.TeacherList)    {%>   <tr>    <td>     <%=teacher.tno%>    </td>    <td>     <%=teacher.tname%>    </td>    <td>     <%=teacher.tsex%>    </td>    <td>     <%=teacher.tbirthday%>    </td>    <td>     <%=teacher.prof%>    </td>    <td>     <%=teacher.depart%>    </td>   </tr>   <% } %>  </tbody> </table>  <div id="window" style="display:none;"> <input type="hidden" id="sno" name="sno" value="" /> 姓名：<input type="text" id="sname" name="sname" /><br /> 性别：<input type="text" id="ssex" name="ssex" /><br /> 生日：<input type="text" id="sbirthday" name="sbirthday" onClick = "WdatePicker()" /><br /> 班级：<input type="text" id="sclass" name="sclass" /><br /> </div></asp:Content>

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? pi, string sclass)  {   int PageIndex = pi ?? 1;   int PageSize = 5;   string sClass = sclass == null ? "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? index, int? pageSize)  {   if (index == null) { index = 1; }   if (pageSize == null) { pageSize = 10; }   this.TotalCount = source.Count();   this.PageSize = pageSize.Value;   this.PageIndex = index.Value;   this.AddRange(source.Skip((index.Value - 1) * pageSize.Value).Take(pageSize.Value));  }  public int TotalPage  {   get { return (int)System.Math.Ceiling((double)TotalCount / PageSize); }  }  public int TotalCount  {   get;   set;  }  /// <summary>/// /// </summary>  public int PageIndex  {   get;   set;  }  public int PageSize  {   get;   set;  }  public bool IsPreviousPage  {   get   {    return (PageIndex > 1);   }  }  public bool IsNextPage  {   get   {    return ((PageIndex) * PageSize) < TotalCount;   }  } } public static class Pagination {  public static PagedList<T> ToPagedList<T>(this IOrderedQueryable<T> source, int? index, int? pageSize)  {   return new PagedList<T>(source, index, pageSize);  }  public static PagedList<T> ToPagedList<T>(this IOrderedQueryable<T> source, int? index)  {   return new PagedList<T>(source, index, 10);  }  public static PagedList<T> ToPagedList<T>(this IQueryable<T> source, int? index, int? pageSize)  {   return new PagedList<T>(source, index, pageSize);  }  public static PagedList<T> ToPagedList<T>(this IQueryable<T> source, int? index)  {   return new PagedList<T>(source, index, 10);  } }}

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)  {   return MikePager<T>(html, data, action, null);  }  public static string MikePager<T>(this HtmlHelper html, PagedList<T> data, string action, object 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, 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 ? (data.PageIndex - 5) : 1;   int end = (data.TotalPage - start) > 9 ? start + 9 : data.TotalPage;   RouteValueDictionary vs = valuedic == null ? new RouteValueDictionary() : valuedic;   var builder = new StringBuilder();   builder.AppendFormat("<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(" ");    vs["pi"] = data.PageIndex - 1;    builder.Append(Html.LinkExtensions.ActionLink(html, "上一页", action, controller, vs, null));    builder.Append(" ");   }   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> ");    }    else    {     builder.Append(" ");     builder.Append(Html.LinkExtensions.ActionLink(html, i.ToString(), action, controller, vs, null));    }   }   if (data.IsNextPage)   {    builder.Append(" ");    vs["pi"] = data.PageIndex + 1;    builder.Append(Html.LinkExtensions.ActionLink(html, "下一页", action, controller, vs, null));    builder.Append(" ");    vs["pi"] = data.TotalPage;    builder.Append(Html.LinkExtensions.ActionLink(html, "末页", action, controller, vs, null));   }   builder.Append(" 每页" + data.PageSize + "条/共" + data.TotalCount + "条 第" + data.PageIndex + "页/共" + data.TotalPage + "页 </div>");   return builder.ToString();  }  #endregion }}

效果图：
