Why don't my Javascript prompts show up from my Express.IO .ejs file?
Question
I am relatively new to JavaScript and subsequently Node + Express.IO. I am trying to build a page that will track in real time connections made by different 'users' to the server. Consequently, when I do include all the functions from the io module, my prompt() and alert do not work anymore. I am running nodemon app.js from my terminal and no compilation errors are showing up when I do so. The alert and prompt work again when I remove all the io functions.
These are the contents of my index.ejs <body> tag:
<body>
<h1>Chatroom</h1>
<script>
alert("Hello!");
var name = prompt("What is your name?");
io.connect();
io.emit.('got_a_new_user', {name: name});
io.on('new_user', function(data) {
//render this new info in the HTML
var users = data.users;
console.log(users);
if (users != undefined) {
console.log("\n\n\n" + users);
// if users is defined, append the new division containing the username
}
});
io.on('disconnect_user', function(data) {
var users = data.users;
if (users != undefined) {
// If users is defined remove the corresponding HTML element
}
});
</script>
<div id="container">
</div>
</body>
Any help would be much appreciated.

Adding example for the comment added by UKatz,
You will have to connect socket.io from the client as follows,
index.ejs
<script src="http://ip:port/socket.io/socket.io.js"></script>
<script type="text/javascript">
var socket = io.connect('http://ip:port');
socket.emit('got_a_new_user', {name: name});
</script>
Check socket.io documentation for how to connect socket.io with client.
