Yes, clearly; if the processing is different for different element
then a delegation model requires you to determine which element you
are processing and choose your processing accordingly.
If each item is distinct, give them all an HTML 'id', and just use
that:
function doIt(e) {
var element = e.findElement('.item');
var id = element.id;
If there are classes of them, it's easiest to use CSS classes:
<span class='item click_class_1'> ...
function doIt(e) {
var element = e.findElement('.item');
var class_1 = element.hasClassName('click_class_1');
or more generally
function doIt(e) {
var element = e.findElement('.item');
if (var matches = element.className.match(/click_class_(\n+)/) {
var clickclass = matches[1]);
