I understand that the way to see if there are any elements on the page
with the class of foo is this: $('.foo')
On a page with such elements, I will get a result like: jQuery(p.foo,
p.foo) and if there are no matching elements, I will get jQuery() --
or at least that's how it's displayed in

Instead, I do it like this (since zero is false-y in JavaScript):
if ( $('.foo').length ) {
alert('at least one matching element');
} else {
alert('nothing matches');
}
But is that the preferred way of
2 matches
