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...

$$('#my_id') // works, and grabs one element
             // but still returns a group
             // so therefore
$$('#my_id')[0]
             // is the same as
$('my_id')
