Chuangneng wcf is the first choice, the code is very simple, as follows:

Copy the code The code is as follows:

 
using System; 
using System.Data; 
using System.ServiceModel; 
using System.ServiceModel.Activation; 
using System.ServiceModel.Web; 
using System.Web.Script.Services; 

[ServiceContract(Namespace = "")] 
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
[ServiceBehavior(IncludeExceptionDetailInFaults = true)] 
public class imgService 
{ 
 // To use HTTP GET, add the [WebGet] attribute. (Default ResponseFormat is WebMessageFormat.Json) 
// To create an operation that returns XML, 
// add [WebGet(ResponseFormat=WebMessageFormat.Xml)], 
// and include the following in the operation body Line: 
// WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml"; 
[OperationContract] 
[WebGet(RequestFormat=WebMessageFormat.Json,ResponseFormat=WebMessageFormat.Json)] 
/ /[WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json,BodyStyle = WebMessageBodyStyle.WrappedRequest)] 
public DataTable GetDataTable(string pz) 
{ 
// here Add operation implementation 
DataSet ds = WebBase.GetDS(WebBase.meinvRepository, string.Empty, " body_id desc",pz); 
if (ds.Tables.Count > 0) 
return ds. Tables[0]; 
return null; 
} 

// Add more operations here and mark them with [OperationContract] 
} 

Explain that wcf has a GetDataTable method. There is a parameter pz indicating the number of rows of returned data. The returned table is used as json data for jquery

The page calling method is also very simple:

Copy code The code is as follows:

<%@ Page Language="C#" EnableViewState="false " AutoEventWireup="true" CodeFile="Default.aspx.cs"
Inherits="jquerywcf_Default" %>

Explain that the data returned by wcf is mainly obtained through the getjson method of jquery. The parameter passing method:

$.getJSON(url, { pz: "6" }, function (msg) {alert(msg.d)});Here are the 6 pieces of data returned and the attributes added to the svc of wcf:
Factory=System.ServiceModel.Activation.WebScriptServiceHostFactory and the configuration of web.config:

Copy code The code is as follows:
