Using JavaScript or jQuery really depends ...

So, as the Javascript comments suggest: #. $ (document); The first option will apply the jQuery library methods to a DOM object (in this case, the document object). $ ('#mydiv') The second option will select every. that has the attribute set to "mydiv". $ ('p.first') The third option will select all of the.
