Selectors in
MooTools and JQuery

There are two methods of getting DOM elements (1) by id and (2) by css selector.

JQuery grabs everything by css selector:

$('#my_id')   // grabs a single element
$('.all_of_this_class')  // grabs a collection

MooTools does it too, but it's easier to read:

$('my_id')   // grabs a single element (by id)
$$('.all_of_this_class'// grabs a collection

One other note is that in MooTools...

$$('#my_id'// works, and grabs one element
             // but still returns a group
             // so therefore
// is the same as

Read a MooTools book review about a book that further demonstrates MooTools DOM selection techniques.
