2. 另一个类为VCHandler.cs的文件，其后台代码为:
using System;
using System.Data;
using System.Collections.Generic;
using System.Text;
using System.Web;
namespace VCSharePoint.BL
{
public class VCHandler:IHttpHandler
{

}
public void ProcessRequest(HttpContext context)
{
context.Response.Clear();
string yearValue = context.Request["Year"] == null ? DateTime.Today.Year.ToString() : context.Request["Year"].ToString();
string monthValue = context.Request["Month"] == null ? UNITS.GetCurrMonth : context.Request["Month"].ToString();
string data = string.Empty;
data = JSONConverter.GetJSONData(GetRankingTable(yearValue, monthValue));
context.Response.ContentType = "application/json";
context.Response.ContentEncoding = Encoding.UTF8;
if (data.Length == 0)
data = "{\"NoResult\": \"this is no result\"}";
context.Response.Write(data);
}
private DataTable GetRankingTable(string yearValue,string monthValue)
{
BL.BLCalculate BlCinstance = new BLCalculate(yearValue, monthValue);
return BlCinstance.GetDataCalc();
}
#endregion
}
}
3. 有一个显示文件网页文件为VC Ranking Chart.aspx， 其后台代码为：其引用了一个jQuery库
