try changing your url to:

url: "http://localhost:59191/Service1/DoWork",

No its not working

put a breakpoint inside DoWork(string id) and see if the webservice gets called.

also the return type of DoWork is not a proper JSON string

thanks for the reply..

no its no entering into WCF service, it is directly calling ajax callback [error] function
and one more thing if i try to run my wcfservice directly it displaying
"Metadata publishing for this service is currently disabled."

Solution 2

Change Your Service annotations like below.Please make sure that your service is working or not

C#

[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate ="/DoWork")]
 [OperationContract]

Hope this helps
