Topic:
jQuery;;
In JQuery,
is $(document).ready(function() the same as $(function () { }
is $(document).ready(function() the same as $(function () { }
Expert: Rob Jurd replied at 2024-07-27 19:11:32
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.
More info on frameworks here:

And JavaScript objects (that is all jQuery is)

Force accept. There is no difference between the two. One is short hand for the other

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

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,
Yes, they are both the same.

Scott, you agree ?
Expert: duncanb7 replied at 2024-07-24 02:42:53
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.

@duncanb7, I'm just trying to double check because we seem to have different answers for the same thing.
I may be confused, but are you talking about pure javascript? or jquery?
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

Accepted Solution

160 points EXCELLENT
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.
Expert: duncanb7 replied at 2024-07-23 23:19:35
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
