jQuery new Object .bind

I've come across a code snippet that i am trying to understand. I did not find it anywhere. The code still works fine. Its about the .bind function of jQuery:

$(new Object()).bind()

what does the bind function of jQuery do with " new Object() ". Can someone elaborate?! Thanks.

I've got it solved. For someone who is interested-> There are two parts to it:

<a id="refButton" href="#">Click Me !!</a>

**Part 1:**   


    $(new Object()).bind("pressMe", function(event, data){
             $(document).ready(function(){
                   $('#refButton').bind("click",function(){
                      alert("Hi There !!");
                    });
             });
        });


**Part 2**

    if(some condition == TRUE){
      $.event.trigger("pressMe");
    }

So, everybody knows that "$(document).ready(function(){" gets executed first - but - in this way only when Part2 condition is TRUE than it triggers the "pressMe" event defined in Part1 which ultimately listens to the click event of the #refButton Id.

But it still remains a mistery to me how the empty new Object() - disables the "$(document).ready(function(){" functionality till the trigger is activated.

But thanks to all who answered.

That statement by itself won't do anything, really, except possibly result in a runtime error. The jQuery "bind()" method requires at least one parameter.

Even with a parameter, it won't do anything, however, because it's all about event handler binding. It doesn't make sense to do that to a plain JavaScript object.

The "bind()" call is normally used like this (though there are variations):

$('selector').bind('event-name', function(ev) { /* event handler code */ });

The "selector" string is used to find one or more DOM elements in a page.

$(new Object()).bind("something", function(event, data){ });

This means that you are binding a function delegate with parameters "event" and "data" to new object's "something" event. Whenever the newly created object fires "something" event, the function will execute.
