MVC jQuery.Ajax非同步實作增刪改查與分頁_jquery

本文實例為大家分享了mvc jquery.ajax非同步實現增刪改查和分頁的具體程式碼，供大家參考，具體內容如下

1、model層程式碼

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層程式碼
