I have my signalr running on a separate domain. We will have multiple applications using it to send and receive messages. I created the connection and hub proxy using the following code

connection = $.hubConnection("https://someurl.com", { useDefaultPath: false });
            chatHub = connection.createHubProxy('chatHub');

I can get messages from the server sent to the client using the following code which works fine

chatHub.on('receiveEntityMessage', function (chatMessage) {
                if (chatMessage) {
                    console.log(chatMessage.Message);
                }
            });

Now I dont know how to call server functions with parameters from the client. Can anybody please help me with this?

Since i'm not sure what is the language of your server side, i am going to provide a C# example.

C# Hub method example:

public class chatHub: Hub {

    public void YourHubMehotd(int firstParam, string secondParam){

        //The action of your method

    }

}

JS client side:

You can call your hub method like this:

{The variable with the hub connection}.server.{the method you want to call}( {the parameters} )

Example:

chatHub.server.YourHubMehotd(1,"Example");

I recomend to create a js function to call the hub method.

function callMyHubMethod(firstParam, secondParam){

    chatHub.server.YourHubMehotd(firstParam, secondParam);

}
