所以我有一个内置于node.js和socket.io here的聊天室我可以看到旁边的用户名加入消息并留下消息但不是旁边他们自己发送的消息是我的服务器代码
io.on('connection', function (socket) {
socket.on('adduser', function(username){
socket.username = username;
socket.room = 'General-Chat';
usernames[username] = username;
socket.join('General-Chat');
socket.broadcast.to('General-Chat').emit('updatechat', '<b class="servertxt">SERVER: </b>', socket.username + ' has connected to this room' + '<hr>');
socket.emit('welcomeuser', '<b class="servertxt">SERVER:</b> Welcome ', socket.username + '<hr>');
socket.emit('updaterooms', rooms, 'room1');
});
socket.on('sendchat', function (data) {
// we tell the client to execute 'updatechat' with 2 parameters
io.sockets.in(socket.room).emit('updatechat', socket.username, data);
});
socket.on('switchRoom', function(newroom){
socket.leave(socket.room);
socket.join(newroom);
socket.emit('updatechat', '<b class="servertxt"> SERVER </b>', 'you have connected to '+ newroom + '<hr>');
// sent message to OLD room
socket.broadcast.to(socket.room).emit('updatechat', '<b class="servertxt"> SERVER </b>', socket.username+' has left this room <hr>');
// update socket session room title
socket.room = newroom;
socket.broadcast.to(newroom).emit('updatechat', '<b class="servertxt"> SERVER </b>', socket.username+' has joined this room <hr>');
socket.emit('updaterooms', rooms, newroom);
});
console.log('a user connected');
socket.on('disconnect', function () {
console.log('user disconected');
});
socket.on('chat-message', function (message) {
console.log('message:', socket.username+': ' + message.text);
//excludes "socket" from getting the emit
socket.broadcast.to(socket.room).emit("chat-message",message);
});
});
这是我的index.html脚本
<script>
var socket = io();
socket.on('connect', function(){
socket.emit('adduser', prompt("What's your name?"));
});
socket.on('updatechat', function (username, data) {
$('#chatlog-display-div').append(username + data);
});
socket.on('welcomeuser', function(data, username){
jQuery("#chatlog-display-div").append(data + username);
});
socket.on('updaterooms', function(rooms, current_room) {
$('#rooms').empty();
$.each(rooms, function(key, value) {
if(value == current_room){
$('#rooms').append('<div id="chatroom-box"><center>' + value + '<center></div><hr>');
}
else {
$('#rooms').append('<div id="chatroom-box"><center><a id="chatroom-box-link" href="#" onclick="switchRoom(\''+value+'\')">' + value + '</a></center></div><hr>');
}
});
});
function switchRoom(room){
socket.emit('switchRoom', room);
}
$('form').submit(function(e) {
e.preventDefault();
//gets the value from the message text feild and sets it as the message var
var message = {
text : $('#chat-box-div-txtinpt').val()
}
if (message.text.trim().length !== 0) {
socket.emit('chat-message',message);
//append the message to the chatlog-display-div
$('#chat-box-div-txtinpt').focus().val('');
jQuery("#chatlog-display-div").append('<div>'+message.text+'</div><hr>');
}
});
socket.on('chat-message', function (message) {
jQuery("#chatlog-display-div").append('<div>'+message.text+'</div><hr>');
});
</script>
