No, it does not cache. Each time you make a page query, a new call is made.
For better performance, always cache commonly used selectors:
$myID = $('#myID'); // $ used for initial var to indicate a jQuery object
var text = $myID.text();
var color = $myID.css('color');
Also, you should always use the raw ID reference where possible as it's far
more performant than tacking on a tag name first:
$myID = $('#myID'); // this performs better than the line below
$myID = $('div#myID'); // avoid this where possible, performance will
degrade

Subject: [jQuery] does selectors $ cache?
does selectors cache? for example, if I do $('#myid') twice, does it search
through the document twice for myid?
