error when calling the distributeMessage method using now.js

Question

Started playing with the now.js framework. Using the example code in now.js I'm trying to implement a chat. Including here for completeness.

<script src="http://localhost:8080/nowjs/now.js" type="text/javascript"></script>

<!-- HTML for Chat Here  -->

$(document).ready(function() {

  now.receiveMessage = function(name, message) {
    $(".chattext").append("<br>" + name + ": " + message);
    $(".chattext").attr({ scrollTop: $(".chattext").attr("scrollHeight") });
  }

  $("#send-button").click(function() {
    now.distributeMessage($("#text-input").val());
    $("#text-input").val("");
  });

  now.name = prompt("What's your name?", "")

});

I've got the node.js server with now.js working properly.

I'm trying to extend the chat so that when a user enters their name, a message is sent to the server noting that " has now joined the chat." The example code prompts a user for a name and sets that to the now object's name.

now.name = prompt("What's your name?", "");

At this point, the now object is available. So instead of simply setting the now.name, I'm trying to set the now.name AND send a message by calling distributeMessage('John has joined chat.')

var p = prompt("What's your name?", "");
if (!p) {
    // errs here
} else {
    now.name = p;
    now.distributeMessage(now.name + " has joined chat.");
}

Chrome and firefox report an error that reads

Object #<Object> has no method 'distributeMessage'.

I don't understand why. The now.name property can be set. The console log shows the object with get distributeMessage and set distributeMessage functions. I can send the message when I click on the 'send-button' element. But, I am unable to call the distributeMessage at this point.

Is the now object not fully loaded when I try to make the method call? Do I need to include some sort of 'now' onLoadReady method? What do I need to do in order to fire off the now.distributeMessage method after the prompt?

I've found a method to address my issue. I need to surround the call to distribute message with a

now.ready(function() {
  now.distributeMessage(now.name + " has joined chat.");
})

It seems the client side now namespace was available but all serverside now calls still required javascript to finish processing.

It is better to update your question rather than answering it by yourself if this still not solving your question. – lig Dec 15 '11 at 19:17
Thanks lig, using now.ready does resolve the problem and thus answers my question. Is there something I can do to make that clearer in my answer? – John Ramos Dec 16 '11 at 19:39
I was facing the same problem, and it still doesn't resolve my issue. – Juzer Ali Apr 25 '12 at 03:42
