Check whether a DOM element exists using jQuery

A straightforward little post: if you want to detect whether a DOM element actually exists on the page (perhaps you're flying in the blind), you can write if ($('selector').length) { // Foo }. If the element is present, it'll evaluate to true and you can work from there.
