通过WebSockets实现聊天室

Question

我正在尝试使用网络套接字为我的网站实现聊天.Gobal聊天工作正常。但我不知道如何建立单独的聊天室。我已经制作了数组来存储单独的连接但是。每次打开新连接并添加到阵列时，消息都会全局发送到所有打开的套接字。

在这里添加js代码。

＆＃13;

＆＃13;

var sockets = []; //array that stores connections


function addText(e) {
  console.log(activeChatWindow + " " + e);
  if (isMyMsg(e)) {
    $("#" + activeChatWindow).append($("<p class=\"Msg\" ></p>").text(e));
  } else {
    $("#" + activeChatWindow).append(
      $("<p class=\"Msg\" id=\"recvMsg\"></p>").text(e));
  }
  $("#userInput").val("");

}

function sendText(user) {

  var msg = formatText();
  msg += $("#userInput").val();
  console.log(sockets[user]);
  sockets[user].send(msg);

}

function formatText() {
  var date = new Date();

  var text = u;
  text += "[" + date.getDate() + "." + (date.getMonth() + 1) + "." + date.getFullYear() + ":" + date.getHours() + ":" + date.getMinutes() + ":" + date.getSeconds() + "]: ";
  return text;

}

function isMyMsg(e) {
  var i = e.indexOf("[");
  var user = e.slice(0, i);

  if (user == u)
    return true;

  return false;

}





function openNewConnection(user) {
  sockets[user] = new WebSocket("ws://localhost:8080/socket");
  console.log(sockets[user]);
  sockets[user].onopen = function(event) {

    console.log('Connection open!');

  };

  sockets[user].onmessage = function(event) {
    console.log(event.data + " " + user);
    addText(event.data);
  };

}

$(window).load(


  function() {



    for (var friend in myFriends) {
      loadFriend(myFriends[friend], friend);
      console.log("hello");

    };
    $("#send").click(function(e) {
      sendText(activeChatWindow);

    });

    $("#userInput").keypress(function(e) {

      if (e.which == 13) {
        e.preventDefault();
        sendText(activeChatWindow);
      }

    });



  });
