jquery调用wcf并展示出数据的方法

关键词：JQueryJS
首选创能wcf，代码很简单，如下：
复制代码 代码如下:

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
{
// 要使用 HTTP GET，请添加 [WebGet] 特性。(默认 ResponseFormat 为 WebMessageFormat.Json)
// 要创建返回 XML 的操作，
// 请添加 [WebGet(ResponseFormat=WebMessageFormat.Xml)]，
// 并在操作正文中包括以下行:
// 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)
{
// 在此处添加操作实现
DataSet ds = WebBase.GetDS(WebBase.meinvRepository, string.Empty, " body_id desc",pz);
if (ds.Tables.Count > 0)
return ds.Tables[0];
return null;
}

// 在此处添加更多操作并使用 [OperationContract] 标记它们
}


说明一下，wcf就一个GetDataTable方法，有一个参数pz表示返回数据的行数，返回的table以json数据给jquery使用

页面调用方法也很简单：

复制代码 代码如下:

<%@ Page Language="C#" EnableViewState="false" AutoEventWireup="true" CodeFile="Default.aspx.cs"
Inherits="jquerywcf_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
<script src="../Scripts/jquery-1.4.1-vsdoc.js" type="text/javascript"></script>
</head>
<body>
<form id="form1" runat="server">
<div class="main">
<ul><li><a></a></li></ul>
</div>
<div>
<script type="text/javascript">
function sendAJAX(data) {
var url = "<%=_url %>imgService.svc/GetDataTable";

$.getJSON(url, { pz: "6" }, function (msg) {
$(msg.d).find("Table").each(function (i) {
var rq = $(this).children("Body_AddTime").text().split('T')[0].replace("-", "").replace("-", "");
rq = rq.substring(0, rq.length - 2);
var html = '<li><a href="http://meinv.vs2010.com/topic/' + $(this).children("Body_MuLuID").text() + '/' + rq + '/show-id' + $(this).children("Body_ID").text() + '.html" target="_blank"><img src="http://meinv.vs2010.com/' + $(this).children("Body_Tu").text() + '" />' + $(this).children("Body_Name").text() + '</a></li>';
$(".main ul").append(html);
});
});

}


$(function () {
sendAJAX();
});
</script>
<div id="msg">
</div>
</div>
</form>
</body>
</html>

说明一下，主要是通过jquery的getjson方法去取得wcf返回的数据，传参方法：

$.getJSON(url, { pz: "6" }, function (msg) {alert(msg.d)});这里是返回6条数据还有wcf的svc上加上属性：
Factory=System.ServiceModel.Activation.WebScriptServiceHostFactory还有web.config的配置：
复制代码 代码如下:
