jquery - Calling a WebMethod using jQueryAjax "GET"

Question

i have a ajax request which works well using "POST" but when used "GET" it gives me the following error,

{"Message":"An attempt was made to call the method u0027GetSomethingu0027 
using a GET      request, which is not allowed.","StackTrace":" at 
System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData 
methodData, HttpContext context)
 at 
System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, 
WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}

so here is my code, on the client side,

function test() {
        $.ajax({
            url: "Default4.aspx/GetSomething",
            type: "GET",
            dataType: "json",
            contentType: "application/json; charset=utf-8",
            success: function (res) { debugger; alert(res.d); },
            error: function (res) { debugger; alert("error"); }
        });
    }

on the server side,

[WebMethod]
public static string GetSomething()
{
    return "got something";
}

any reason why i am getting error when used "GET" ??

If you want to invoke it using GET, you need to add:

[WebMethod]
[ScriptMethod(UseHttpGet=true)]
....
