I have a webmethod like this:

[WebMethod(EnableSession = true)]
public string testMethod(string param1, string param2="default value")
{
    .......
}

I am trying to callthis method using jquery omitting the optional parameter, and the webmethod doesn't get hit.

$.ajax({
    type: "POST",
    url: url,
    data: { "param1": "value1" }
}).complete(function (data) {....});

I works only when I pass the second parameter also. Is there any way to solve this ?

I don't think you can use Optional Params with webservice methods, you'll probably need to Overload the method...

[WebMethod(EnableSession = true, MessageName = "testMethod"))]
public string testMethod(string param1, string param2)
{
      .......
}

[WebMethod(EnableSession = true, MessageName = "testMethod")]
public string testMethod(string param1)
{
      testMethod(param1, "default value");
}

EDIT: Article Link.

There's also an article here worth reading for additional approaches, and although it concludes not to use Overloading, I guess it's your decision.
