client can't send data to server side?

I want to build a connection from browser to server side which written in node.js

when the client side connect to the server , the server side will send a message to client and the server will receive message when the client click the send button.

but the client side can receive the message from server side , but server side can't receive message from client side

client side code

<center>
    <input id="send" type="submit" value="send">
    <p id="recv"></p>
</center>

<script src="library/socket.io.js"></script>
<script type="text/javascript">
    var socket = io.connect("http://127.0.0.1:7000");
    var send = document.getElementById("send");
    var recv = document.getElementById("recv");

    send.addEventListener("click",function () {
        socket.emit("message","message_from_client");
    });

    socket.on("message",function (data) {
        recv.innerHTML = data;
    });
</script>

server side client

var socket = require("socket.io").listen(7000);

socket.on("connect",function () {
    console.log("connect");
    socket.emit("message","message_from_server");
});

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

});

Can you try this code on server side? I seen it work.

var socket = require("socket.io").listen(7000);

socket.on("connect", function(client) {
    console.log("connect");
    client.emit("message", "message_from_server");

    client.on("message", function(data) {
        console.log(data);

    });
});

You can check sample code and document on this link

Try using io.sockets.emit('event', message) on the client. This will send the message to all connected sockets, including the server.
