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() { $(this).dialog("close"); //当点击取消按钮时，关闭窗口 }, "添加": function() { //当点击添加按钮时，获取各参数的值 var sno=$('#sno').val(); var sname=$('#sname').val(); var ssex=$('#ssex').val(); var sbirsthday=$('#sbirthday').val(); var sclass=$('#sclass').val(); $.ajax({ type:'post', url:'/Student/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);" sno="<%=student.sno %>" sname="<%=student.sname %>" ssex="<%=student.ssex %>" sbirthday="<%=student.sbirthday %>" sclass="<%=student.sclass %>">修改</a> <a href="javascript:void(0);" sno="<%=student.sno %>">删除</a> </td> </tr> <% } %> </tbody> <tfoot> <tr> <td> 全选 </td> <td colspan="5"> <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"> <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 " : 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>"); 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>" + 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 } }
