MVC+jQuery.Ajax异步实现增删改查和分页

2024-10-02 01:59:10

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

ASP.NET MVC分页和排序功能实现

分页和排序,应该是软件开发中,需要必知必会的技能了,对于分页,网上很多教程,当然,别人终究是别人的,只有自己理解,会了,并且吸收之后,再用自己的语言,传授出来,这才是硬道理.好了,废话说多了.现在我们进入正题: 这里,我打算使用EF Code-First方式分页控件就是用PagedList.MVC,来做分页,对于排序,实现的思路是,加载数据出来之后,默认是升序排序,然后我们点击一下相应的列标题,就按照该字段降序排序,查数据.思路明确了,就开始干吧! 1.首先新建一个空白的MVC项目,在Model
MVC生成页码选择器返回HTML代码详解

我主要讲此代码用于MVC的分布页. 先看最终效果最终效果: 样式为bootstrap3中的分页"pagination",如果不使用bootstrap单独提出来并不大页码生成代码为: public string GetPaginationHtml(PaginationViewModel p) { var PageNum = p.Page;//当前页码(页码从1开始) var PageCount = p.PageCount;//总页数 var ItemCount = p.ItemCoun
ASP.NET MVC 5使用X.PagedList.Mvc进行分页教程(PagedList.Mvc)

ASP.NET MVC中进行分页的方式有多种,但在NuGet上使用最广泛的就是用PagedList.X.PagedList.Mvc进行分页.(原名为:PagedList.Mvc,但是2014年开始,作者将项目名称改名字为"X.PagedList.Mvc"),用这个插件的话会非常便利,大家可以试试,接下来将给大家讲下如何安装这个NuGet插件. ASP.NET MVC 5使用X.PagedList.Mvc进行分页教程(原名为PagedList.Mvc) 1.工具--NuGet 程序包管理
springmvc 分页查询的简单实现示例代码

目前较常用的分页实现办法有两种: 1.每次翻页都修改SQL,向SQL传入相关参数去数据库实时查出该页的数据并显示. 2.查出数据库某张表的全部数据,再通过在业务逻辑里面进行处理去取得某些数据并显示. 对于数据量并不大的简单的管理系统而言,第一种实现方法相对来说容易使用较少的代码实现分页这一功能,本文也正是为大家介绍这种方法: 代码片段: 1,Page.java package com.cm.contract.common; import org.apache.commons.lang.Strin
