Украсьте свой класс AjaxService следующим образом:
[WebService(Description = "Web services to query the book database.", Namespace ="http://www.your-site-url.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class AjaxService: System.Web.Services.WebService
{
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public bool CheckUsernameAvailability(string userName, Options options)
{
return this.WriteToSql(options);
}
private bool WriteToSql(Options options)
{
bool result = false;
try
{
SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["SqlConnectionString"].ConnectionString);
SqlCommand command = new SqlCommand("INSERT_OPTION", connection);
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add("@Option1", SqlDbType.NVarChar, 20).Value = options.Option1;
command.Parameters.Add("@Optoin2", SqlDbType.Bit).Value = (options.Option2 == true ) ? 1 : 0;
connection.Open();
command.ExecuteNonQuery();
connection.Close();
result = true;
}
catch(Exception ex)
{
//do some logging here...
result = false;
}
return result;
}
}
[Serializable]
public class Options
{
public string Option1 { get; set; }
public bool Option2 { get; set; }
}
Тогда ваш JQuery будет выглядеть так:
$( function(){
$.ajax({
type: 'POST',
contentType: "application/json; charset=utf-8",
url: "AjaxService.asmx/CheckUsernameAvailability",
data: { userName: 'TestUsername', options: { Option1: 'test', Option2: 'false' } },
success: function(msg) {
//display acknowledgement here. DO NOT USE EVAL! It's bad.
var result = eval(msg);
alert(result);
}
});
});
