using System.ServiceModel.Activation;
using System.ServiceModel.Web;
using System.Text;
namespace Wcftestthrajax

{
// To use HTTP GET, add [WebGet] attribute. (Default ResponseFormat is WebMessageFormat.Json)

[OperationContract]
[WebGet(UriTemplate = "", ResponseFormat = WebMessageFormat.Json)]
public string DoWork(string id)
{
// Add your operation implementation here
return "hello wcf" +id ;

推荐答案
.ajax（{
type：POST，
url：http：// localhost：59191 / Service1。 svc / DoWork，
数据：{'id'：'+ a +'}，
contentType：application / json; charset = utf-8，
dataType：json，
成功：OnSuccessCall，
错误：OnErrorCall
}）;
}
函数OnSuccessCall（响应）{
alert（response.d）;
}
函数OnErrorCall（响应）{
alert（Error）;
}

更改您的服务注释，如下所示。请确保您的服务是否正常工作
Change Your Service annotations like below.Please make sure that your service is working or not
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate ="/DoWork")]
[OperationContract]
希望这有助于
