I\'m a little confused about all the different ways to create a new jQuery object.
the relevent docs seem to be: http://api.jquery.com/ready/ http://api.jquery.c
Well if you are only using jQuery then $() is equivalent to jQuery(). So that covers half of them.
Then, if you use $() instead of $(document).ready, those are the same. In this case, it is just a helper function. You may want to add ready on something else for example, in which case, you would do: $(foo).load({})
Last, I don't know what you mean with $().ready because you have to pass a parameter.
