本文向大家介绍MVC+jQuery.Ajax异步实现增删改查和分页,包括了MVC+jQuery.Ajax异步实现增删改查和分页的使用技巧和注意事项,需要的朋友参考一下

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

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 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);

 }
 /// <summary>

  JsonResult json = new JsonResult();
  json.Data = new
  {

  };
  return json;
 }
 /// <summary>

  JsonResult json = new JsonResult();
  json.Data = new

  };
  return json;
 }

 /// <summary>

  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)

  int start = (data.PageIndex - 5) >= 1 ? (data.PageIndex - 5) : 1;
  int end = (data.TotalPage - start) > 9 ? start + 9 : data.TotalPage;

  var builder = new StringBuilder();
  builder.AppendFormat("<div class=\"mike_mvc_pager\">");

  if (data.IsPreviousPage)
  {

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