var nameVal = $("#nameInput").val();
  var msg = $("#messageInput").val();
  var canalVal = $("#canalInput").val();
  flag = true;
  if (nameVal && msg && flag) {
      flag = false;
      window.setTimeout(function () {
          flag = true
      }, 3000)
      socket.emit('message', {
          name: nameVal,
          message: msg,
          canal: canalVal
      })
  };

не срабатывает. вот весь код, может я не так думаю

var socket = io.connect( 'http://localhost:8080' );
$( "#messageForm" ).submit( function() {
	var nameVal = $( "#nameInput" ).val();
	var msg = $( "#messageInput" ).val();
	var canalVal = $( "#canalInput" ).val();
	
	if(nameVal && msg){
	socket.emit( 'message', { name: nameVal, message: msg, canal: canalVal } )
	};
	// Ajax call for saving datas
	$.ajax({
		url: "./ajax/insertNewMessage.php",
		type: "POST",
		data: { name: nameVal, message: msg, canal: canalVal },
		success: function(data) {
			 
		}
		
	});
	
	return false;
});


socket.on( 'message', function( data ) {
	var actualContent = $( "#messages" ).html();
	var newMsgContent = '<li> <strong>' + data.name + '</strong> : ' + data.message
																					.replace(new RegExp("&#D83DDE04",'gi'),"<img src='../packs/basic/D83DDE04.png' height='21' width='21'>")
																					
																					.replace(new RegExp("&#D83DDC8A",'gi'),"<img src='../packs/basic/D83DDC8A.png' height='21' width='21'>") + '</li>';
	var content = newMsgContent + actualContent;
	$( "#messages" ).html( content );
	
});
