Hello there!
As someone new to WCF, I initially thought it would be similar to ASP.NET web services. However, I'm facing an issue where I am unable to call a method from client-side JavaScript. Here is a snippet of my web form:
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
<Scripts>
<asp:ScriptReference Path="~/test.js" />
</Scripts>
<Services>
<asp:ServiceReference Path="~/MyService.svc" />
</Services>
</asp:ScriptManager>
</div>
<button onclick="test()">Click Me</button>
</form>
The interface of my service is defined as follows:
namespace Test
{
[ServiceContract(Namespace = "Test")]
public interface IMyService
{
[OperationContract]
void PerformTask();
[OperationContract]
string Greet();
}
}
Below is the implementation of the service:
namespace Test
{
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class MyService : IMyService
{
public void PerformTask()
{
}
public string Greet()
{
return "Greetings!";
}
}
}
Lastly, here is the JavaScript code being used:
function test() {
Test.MyService.Greet(GreetSuccess, GreetError);
}
function GreetSuccess(result) {
alert(result[0]);
}
function GreetError(error) {
alert(error.toString());
}
It seems that the SayHi() method of the service does not execute, and I am unsure about how to troubleshoot this issue. Any advice or suggestions would be greatly appreciated.
