I believe index() is what you're looking for. According to the API
docs[1], it takes an object and returns its index in the jQ stack or -1 if
the object can't be found.
So your code would be:
<p>aaa</p>
> <p>bbb</p>
> <p class="noinc">ccc</p>
> <p>ddd</p>

Although now that I think about it, you could probably do (untested)
row.each(function(i) {
if($(this).is('.noinc')) {
// do something
} else {
// do something else
}
});
or
row.each(function(i) {
if(jQuery.class.has(this, 'noinc')) {
// do something
} else {
// do something else
}
});
