1. 一般删除网页数据
就是指用户在点击删除的时候，会跳转到DeleteUser.ashx一般处理程序中，并且通过get传参的方式传递一个id的参数，然后在后台处理
<a href='DeleteUser.ashx?id={0}
具体代码如下：
using CZBK.ItcastProject.Model;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Web; namespace CZBK.ItcastProject.WebApp
{
/// <summary>
/// UserInfoList 的摘要说明
/// </summary>
public class UserInfoList : IHttpHandler
{ public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/html";
BLL.UserInfoService UserInfoService = new BLL.UserInfoService();
List<UserInfo>list= UserInfoService.GetList();
StringBuilder sb = new StringBuilder();
foreach (UserInfo userInfo in list)
{ //点击删除跳转的地址
sb.AppendFormat("<tr><td>{0}</td><td>{1}</td><td>{2}</td><td>{3}</td><td>{4}</td><td><a href='DeleteUser.ashx?id={0}' class='deletes'>删除</a></td><td><a href='ShowDetail.ashx?uid={0}'>详细</a></td><td><a href='ShowEdit.ashx?id={0}'>编辑</a></td></tr>",userInfo.Id,userInfo.UserName,userInfo.UserPass,userInfo.Email,userInfo.RegTime);
}
//读取模板文件
string filePath = context.Request.MapPath("UserInfoList.html");
string fileCotent = File.ReadAllText(filePath);
fileCotent = fileCotent.Replace("@tbody",sb.ToString());
context.Response.Write(fileCotent);
} public bool IsReusable
{
get
{
return false;
}
}
}
}
UserInfoList.ashx
DeleteUser.ashx 相关代码展示如下
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web; namespace CZBK.ItcastProject.WebApp
{
/// <summary>
/// DeleteUser 的摘要说明
/// </summary>
public class DeleteUser : IHttpHandler
{ public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
int id; // out id 就是指将值赋值给id
if (int.TryParse(context.Request.QueryString["id"], out id))
{ BLL.UserInfoService UserInfoService = new BLL.UserInfoService();
//如果删除成功
if (UserInfoService.DeleteUserInfo(id))
{
//页面重定向
context.Response.Redirect("UserInfoList.ashx");
}
else
{
context.Response.Redirect("Error.html");
}
}
else
{
context.Response.Write("参数错误!!");
}
} public bool IsReusable
{
get
{
return false;
}
}
}
}
2. 通过Ajax删除网页数据
