Question

I am trying to send some data to my SQL server. With a model at hand. I got an error saying that my AddBug is not a function. Post:29 Uncaught TypeError: chat.client.AddBug is not a function So can someone please help me in debugging this error. I cannot find any mistake and sorry I am totally new to signalR and trying to get somethings up and running for my server.

Answer 1

//hub code

public void AddBug(string id, string name) 
{ 
   //your code
}

//js server call

window.chat.server.addBug($('#txtId').val(), $('#txtName').val());
