Form submission not stopped (OSX + Chrome)
Hi,
I was programming the index.html page and I ran across an error where the return false in the $('form').submit(callback) did not actually stop the callback seen in this block:
$('form').submit(function(){
socket.emit('chat message', $('#m').val());
$('#m').val('');
return false;
});
For anyone else hitting this problem I remedied it by creating a helper method and attaching it to the button. Instead of using a form element I wrapped the "form" in a div element. the code below is what worked for me to complete the example:
<!doctype html>
<html>
<head>
<title>Socket.IO chat</title>
<style>
* { margin: 0; padding: 0; box-sizing: border-box; }
body { font: 13px Helvetica, Arial; }
div { background: #000; padding: 3px; position: fixed; bottom: 0; width: 100%; }
div input { border: 0; padding: 10px; width: 90%; margin-right: .5%; }
div button { width: 9%; background: rgb(130, 224, 255); border: none; padding: 10px; }
#messages { list-style-type: none; margin: 0; padding: 0; }
#messages li { padding: 5px 10px; }
#messages li:nth-child(odd) { background: #eee; }
</style>
<script src="/socket.io/socket.io.js"></script>
<script src="https://code.jquery.com/jquery-2.1.3.min.js"></script>
<script>
var socket = io();
// new code replacing the $('form').submit(...) bit
function pushMessage () {
var mess = $('#m').val();
$('#m').val('');
socket.emit('chat message', mess);
}
socket.on('chat message', function (msg) {
$('#messages').append($('<li>').text(msg));
});
</script>
</head>
<body>
<ul id="messages"></ul>
<div>
<input id="m" autocomplete="off" />
<button onclick="pushMessage()">Send</button>
</div>
</body>
</html>
I was having this issue too. Then realized I just needed to move script tags to the bottom, right before </body>. After doing that, the original chat example code works fine.
just write $(document).ready(function () { $('form').submit(function(){ socket.emit('chat message', $('#m').val()); $('#m').val(''); return false; }); }) where we adding document ready function... now we can put script in head) hope helps)
