一套手写ajax加一般处理程序的增删查改
倾述下感受：8天16次驳回。这个惨不忍睹。
好了不说了，说多了都是泪。
直接上代码 ：
这个里面的字段我是用动软生成的，感觉自己手写哪些字段太浪费时间了，说多了都是泪
ajax.model层的代码：
using System;namespace Ajax.Model{ /// <summary> /// SM_Class:实体类(属性说明自动提取数据库字段的描述信息) /// </summary> [Serializable] public partial class SM_Class { public SM_Class() {} #region Model private int _sm_id; private string _sm_name; private string _sm_grade; private string _sm_class; private string _sm_gender; private int? _sm_age; private DateTime _sm_outtime; private bool _sm_istf; /// <summary> /// /// </summary> public int SM_id { set{ _sm_id=value;} get{return _sm_id;} } /// <summary> /// /// </summary> public string SM_name { set{ _sm_name=value;} get{return _sm_name;} } /// <summary> /// /// </summary> public string SM_Grade { set{ _sm_grade=value;} get{return _sm_grade;} } /// <summary> /// /// </summary> public string SM_Classes { set{ _sm_class=value;} get{return _sm_class;} } /// <summary> /// /// </summary> public string SM_Gender { set{ _sm_gender=value;} get{return _sm_gender;} } /// <summary> /// /// </summary> public int?

ajax.dal层代码：

ajax.bll层代码：

ajax.ui层代码：
先说js脚本把，这里是自己封装的一个ajax.js脚本 就是调用自己手写的这个ajaxhelper.js来实现异步刷新请求。
var ajaxHelper = { markXHR: function () { var xhr; if (window.XMLHttpRequest) { xhr = new XMLHttpRequest(); } else { xhr = new ActiveXObject("Micrsoft.XMLHTTP"); } return xhr; }, //get请求 ajaxGet: function (url, sucessFun) { this.ajaxOpt("get", url,null, sucessFun); }, //post请求 ajaxPost: function (url, data, sucessFun) { this.ajaxOpt("post", url, data, sucessFun); }, //定义ajax的get和post请求 //httpmenthod :get,post //data:发送给服务器的数据，post有值，get为null //sucessFun成功的回掉函数 ajaxOpt: function (httpMenthod, url, data, sucessFun) { //转换成小写字符串 var menthod = httpMenthod.toLowerCase(); //定义xmlhttprequest对象 var ajaxobj = this.markXHR(); //异步对象设置参数，总是异步true ajaxobj.open(httpMenthod, url, true); //判断是get还上post，设置响应报文 if (menthod == "get") { //为了使get请求不取自浏览器缓存，而每次都请求服务器 ajaxobj.setRequestHeader("If-Modified-Since", "0"); } else { //告诉服务器请求的数据类型 ajaxobj.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); } //给一度对象设置回掉函数 ajaxobj.onreadystatechange = function () { if (ajaxobj.readyState==4&&ajaxobj.status==200) { var jsonobj = JSON.parse(ajaxobj.responseText); if (jsonobj.Status == "sucess") { sucessFun(jsonobj); } else { alert(jsonobj.Msg); } } } ajaxobj.send(data); }}
再者我有引用jquery-1.9.1.js 文件 还有一个msgBox.js作为弹出窗体，jquery我想大家应该都有，我就上传下msgBox的js文件的代码吧。
/*{ imghref:图片文件夹所在路径, waitImg:等待图片名, bgImg:背景图片名 }*/function MsgBox(s) { var secondConst = 2000;//系统默认显示时间 var secondWait = 2000;//显示时间 var timer;//计时器 var lf, tp;//左边距,顶边距 var paras = {}; //json参数 function readyMsgBox() { if (s != null){ if (s.imghref != null) paras.imghref = http://www.mamicode.com/s.imghref;

还有两个图片
就是这两个文件，放在一个文件下面 ，用到msgbox的时候把路径添加进去就ok了。
因为我的数据传输都是json格式所以在ui层我直接添加了一个ajaxobj.cs实体类
using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace Ajax.UI{ public class Ajaxobj { private string status; /// <summary> /// 状态 /// </summary> public string Status { get { return status; } set { status = value; } } private string msg; /// <summary> /// 提示 /// </summary> public string Msg { get { return msg; } set { msg = value; } } private object data; /// <summary> /// 数据 /// </summary> public object Data { get { return data; } set { data =http://www.mamicode.com/ value; } } private string url; /// <summary> /// 地址 /// </summary> public string Url { get { return url; } set { url = value; } } } public enum Estatus { sucess=200, error=500 }}
中间有个枚举，是用来判断正确还是错误的..
因为我是用的简单三层就没有下common层，所以在ui层我田间了一个转换序列化json格式的kiss.cs类
using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace Ajax.UI{ public static class kiss { /// <summary> /// json序列化 /// </summary> /// <param name="model"></param> /// <returns></returns> public static string GetJson(object model) { System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer(); return js.Serialize(model); } }}
大体的框架就这些，这些东西我没有怎么去做优化，主要是实现功能
所以想现在上getlist.aspx动态页面的代码，都是用jquery异步请求一般处理程序，有些的不好的地方，希望大家能指出来，我好进行改进，还有一个我没有写样式，就连简单的边框也没有增加。哎，说多了，真的是泪，本来想前两天就把这个东西总结出来的，可是元旦事多，没有办法，只要今天来把它写完，上传，然后出去看人，希望不要有踩踏事件，昨天出去了下，从地铁出来走了半个小时，坐朋友车去了一趟小蛮腰，啥也没有干,感受了下，堵车的滋味，哎...说多了都是泪.另一个朋友说开个车去爬山，堵在半路上，上也不是下也不是，可恶的单行道...呵呵，在这里希望大家开开心心过个节，2014年对我来说真的太悲催了，主要是太菜了...都是泪呀.又闲扯了这么多鬼话.

这个里面大多数我都做了注视，希望大家看的明白，还有我的新增和编辑是一个面板所以会有一个判断
里面有个好用的jquery时间转换.可以作为资源库去使用.希望大家能直接调用就好了.
