There is different between

At $(document).ready(function(),  
The function() will operate after the whole page is completely loaded and DOM is ready.
But
$(function () {   }
is self-start or self calling anonymous function that is just function, it will operate or start as soon as possible when the browser is interpreting your ecma-/javascript  regardless the page being loaded completely or not

These two sets of code below are the same http://api.jquery.com/ready/.  I personally use the later because it is faster to type out.
$( document ).ready(function() {
  // Handler for .ready() called.
});

Open in new window

$(function() {
  // Handler for .ready() called.
});

Open in new window

@duncanb7, I'm just trying to double check because we seem to have different answers for the same thing.  

self calling anonymous function that is just function, it will operate or start as soon as possible when the browser is interpreting your ecma-/javascript

I may be confused, but are you talking about pure javascript? or jquery?
  <script>
    (function(){
 // do something
})();
  </script>

Scott, you are correct and I miss $
And the article mention $(function()) is shorthand for $( document ).ready() at this site. http://learn.jquery.com/using-jquery-core/document-ready/

And my previous post is shown the different between $(document.)ready() and (function()) , javascript self-start function only.

You can test from the following code , if the div tag change color means it work for the code. Finally, it showed only Self-javascript function can not change to green color.

Thank you Duncan.   Your description matched something for pure javascript.  If you add the $ or jquery in front, now you are talking about jquery as you suggest, but then the description you gave is incorrect.

The simple correct answer to the question,
is $(document).ready(function() the same as $(function () {
Yes, they are both the same.

Thanks for your reply , please review my post I didn't suggest anything  and I just verify  it by testing for all of you from your previous post to me.

The answer is Yes to the question and  mentioned at this site

To clarify,

$(document).ready(function() {}); is capturing the "ready" event when the document had loaded.

$(function() {}); is passing an anonymous function to the jQuery class. JQuery is configured such that the anonymous function is only called once the DOM has loaded.

And JavaScript objects (that is all jQuery is)
