Question

I have a WebSocket connection set up for a basic web chat server.

Now, whenever a message is received, it is sent to a function which outputs it on the screen.

socket.onmessage = function(msg){output(msg);}

However, there are certain technical commands which the user can send to the server through the connection which elicit a technical response, not meant to be output on the screen.

How can I grab the server response which immediately follows one of these technical messages?

Do I put a separate socket.onmessage right after the block of code which sends the technical message? I imagine that would take all future messages. I just want the next one.

Ideas?

Answer 1

You can packetise the data, I mean, by a special character/s, form a string like this :

"DataNotToBeShown"+"$$"+"DataToBeShown"; //if $$ is separating character

And then, you can split the string in javascript like this :

var recv=msg.data.split('$$');

So, the data not be shown is in recv[0] and data to be shown, in recv[1]. Then use however you want.
