$(function(){
$('.comment').keyup(function(ev){
var textarea = $(this);
var id = textarea.attr('id');
})
});
The context 'this' in jQuery callbacks is always a DOMElement and always
corresponds to the element to which the event is bound.
You could also get it from ev.target in this case, but they may not always
be the same (if the event has bubbled up to a parent element that has the
bound event). For example
<div><textarea></textarea></div>
If you bind a keyup to the div, then press a key in the textarea, 'this'
will be the div, event.target will be the textarea.
