从客户端访问存储在服务器端对象中的功能

Question

Server-side:

//When a player connects, all the players will get this message.
    game.sockets.emit('entrance', 
        {
            id: socket.id,
            players: [],
            message: 'Player ' + socket.id + ' is online', 
            store: function(id, object){
                this.players.push({id: id, object: object});
            }
        });

Client-side:

socket.on('entrance', function(data){
        console.log(data.message);

        data.store(data.id, new Car('hero').init());    
    });

This gives me the following error:

It console.log 's the message stored in the object without a problem, so It seems like the error somewhere inside the function.

Thanks!

With socket.io, you're sending JSON objects over the wire, and JSON doesn't support the sending of functions: http://www.json.org/

See this post full a detailed approach to do what you're trying to do: Sending anonymous functions through socket.io? (the post talks specifically about anonymous functions, but the same holds true for what you're attempting).
