I have a webserivce with a couple of test methods... [WebService(Namespace = "http://localhost/WebServices")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. [System.Web.Script.Services.ScriptService] public class SystemServices : BaseWebService ajax error 500 { [WebMethod(EnableSession = true)] public string GetDate() { return DateTime.Today.ToShortDateString(); } [WebMethod(EnableSession = true)] public string PerformPISearch(string firstName, string lastName ) { return firstName + lastName; } I can use the $.ajax request to use the GetDate method which does not have parameters with no issue, but I get the 500 Internal Server Error returned from jQuery when I try to run the PerformPISearch method (the web service constructor never gets hit)...So I am assuming I am doing something wrong with the way I am trying to pass the paramters to the method, but I can't figure out what... function PerformSearch() { var strFirstName = (txtFirstName.GetValue() == null ? "" : txtFirstName.GetValue()); var strLastName = (txtLastName.GetValue() == null ? "" : txtLastName.GetValue()); var webserviceURL = '<%= WebServiceURL %>' $.ajax({ type: "POST", url: webserviceURL + "SystemServices.asmx/PerformPISearch", //Can change to use GetDate and it works. data: ({firstName: strFirstName, lastName: strLastName}), //thinking the problem is here 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); } asp.net jquery share|improve this question edited Aug 11 '10 at 22:02 kbr
