处理页：
1.得到List列表
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
string result = "";
string Title = context.Request["page"];
string a = Title;
if (a == "1")
{
IList<QuestionModel> Infos = new QuestionBLL().GetModelList(" id<10 ");
result = JsonConvert.SerializeObject(Infos);
}
else
{
IList<QuestionModel> Infos = new QuestionBLL().GetModelList("id>9 and id<100 ");
result = JsonConvert.SerializeObject(Infos);
}
//总记录数total
//构造json
result = "{\"total\":100,\"rows\":"+result+"}";
context.Response.Write(result);
}
2.增加修改删除
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Wzh.BLL;
using Wzh.Model;
using System.Text;
namespace Web
{
/// <summary>
/// Add 的摘要说明
/// </summary>
public class Add : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
string type = context.Request["type"];
StringBuilder result = new StringBuilder();
if (type == "add")
{
int AddId = add(context); ;
if (AddId == 0)
{
result.Append("{\"errorMsg\":\"添加失败\"}");
}
else
{
result.Append("{\"errorMsg\":false}");
}
}
else if(type=="edit")
{
int EditId = Edit(context); ;
if (EditId == 0)
{
result.Append("{\"errorMsg\":\"编辑失败\"}");
}
else
{
result.Append("{\"errorMsg\":false}");
}
}
else if (type == "del")
{
if (!Del(Convert.ToInt32(context.Request["Id"])))
{
result.Append("{\"sucess\":\"删除失败\"}");
}
else
{
result.Append("{\"success\":true,\"status\":1}");
}
}
context.Response.Write(result.ToString());
}
public int add(HttpContext context)
{
string Title = context.Request["Title"];
string Remark = context.Request["Remark"];
QuestionModel Model = new QuestionModel();
Model.Remark = Remark;
Model.Title = Title;
return new QuestionBLL().Add(Model);
}
public int Edit(HttpContext context)
{
int Id = 0;
Id = Convert.ToInt32(context.Request["Id"]);
string Title = context.Request["Title"];
string Remark = context.Request["Remark"];
QuestionModel Model = new QuestionModel();
Model.Remark = Remark;
Model.Title = Title;
Model.Id = Id;
new QuestionBLL().Update(Model);
return Id;
}
public bool Del(int Id)
{
return new QuestionBLL().Delete(Id);
}
public bool IsReusable
{
get
{
return false;
}
}
}
}
