Match elements via REGEXP in jQuery
One of the odd omissions from jQuery's famous selectors is the ability to filter by regular expression. The usual work-around is to iteratively interrogate each chain element's text in a callback function inside .filter(), but this is a little clunky and feels unnecessasry.
Mitya to the rescue. I've just posted a plugin and core extension which allows precisely this, both via a pseudo selector, :regexp, and via a method, .regexp().
Head over here to download, get usage info or view a demo.
So for example, to use the pseudo selector:
$('selector:regexp(/pattern/)') //etc
or, to achieve the same effect with the method:
$(selector).regexp(/pattern/) //etc
Note that, to use the pseudo method, you'll need to double-escape any characters that need escaping. This is because you're specifying a REGEXP pattern inside a string.
