calling a simple WCF Service from jQuery

Question

I have a very simple WCF Service called pilltrkr.svc. I\'m trying to call this service from jQuery via the following code:

    var jsondata = JSON.stringif         


        

Answer 1

Probably a bit late, but I wrote a couple of blog posts a few years ago about calling WCF from jQuery. This also covers fault handling - which many articles ignore.

Part one and Part two.

what i found in google, might help you.

$(document).ready(function() {
         $("#sayHelloButton").click(function(event){
             $.ajax({
                 type: "POST",
                 url: "dummyWebsevice.svc/HelloToYou",
                 data: "{'name': '" + $('#name').val() + "'}",
                 contentType: "application/json; charset=utf-8",
                 dataType: "json",
                 success: function(msg) {
                     AjaxSucceeded(msg);
                 },
                 error: AjaxFailed
             });
         });
     });
          function AjaxSucceeded(result) {
              alert(result.d);
          }
          function AjaxFailed(result) {
              alert(result.status + ' ' + result.statusText);
          }  

[WebMethod()]
public static string sayHello()
{
    return "hello ";
} 

Answer 3

I figured out how to finally call my simple WCF service from jQuery. I found some source code after reading this link:

http://www.west-wind.com/weblog/posts/2009/Sep/15/Making-jQuery-calls-to-WCFASMX-with-a-ServiceProxy-Client. This link doesn't provide the source but it was another page that referenced this link.

Anyway, I downloaded the code and started to compare my code versus this working project that was calling a WCF Service via jQuery. What I found was that my web.config file was way too complicated so I shorted that up considerably. Then I also realized that my methods were not public. So I made them public and then after a few more tweaks (i.e. taking out the namespaces) the page started to return the simple string I was trying to return.

  <system.serviceModel>
    <services>
      <service name="pilltrakr" behaviorConfiguration="MyServiceTypeBehaviors">
        <endpoint address="" behaviorConfiguration="pilltrakrAspNetAjaxBehavior" binding="webHttpBinding" contract="Ipilltrakr"/>        
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MyServiceTypeBehaviors">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="pilltrakrAspNetAjaxBehavior">
          <enableWebScript/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
  </system.serviceModel>
