Jquery: Selection within a selection

Question

I have an array of different elements stored from a previous selection, call it \'a\'.

How do i then do another select from this previous selection (

Answer 1

a.filter('input').each(function() {
    alert('My name is ' + $(this).attr('name'));
});

To just get a selection from the current selection this way:

var $inputs = a.filter('input');

You can even comma separate selectors:

var $els = a.filter('input, .fooMonger, #something');

See http://docs.jquery.com/Traversing/filter

Answer 2

$(a).find("input")

Answer 3

$('input', a);
