Node.js / Sockets-用户连接，它加载以前的消息，但是将消息加载到所有其他聊天用户，而不是刚刚连接的用户

Question

so I am new to node.js, I am making chat. Basically I have two files: server.js (server side) and script.js (client side). in server side I put this:

in server.js:

socket.on('previousMessages', function (data){
    db.query("SELECT * FROM messages", function (error, results, fields) {
    for(var i=0;i<results.length;i++){
    var obj = results[i];
            socket.broadcast.emit('message', {

        'message' : "hellow",

        'pseudo' : "arleitiss"

    });
    //console.log("break");
}
    });
    });

in script.js:

function addMessage(msg, pseudo){
    $("#chatEntries").append('<div class="message"><p>' +
     pseudo + ' : ' + msg + '</p></div>');
}

    socket.on('message', function(data){
        addMessage(data['message'], data['pseudo']);
    });

So when user logins, enters his nickname, it loads all previous messages from database. Then its' supposed to load them in chat for only that user who connected, but instead: it ignores the user that just connected and loads all messages for other chat users.

So how do I go about fixing this?

Oh yeah and don't mind that I am not using results yet, I am just testing first using basic variables.

Answer 1

In your server you use socket. broadcast .emit what emit a message to all OTHER sockets.

Just do socket.emit .
