It is possible with each. You don't even need a seperate variable to hold the index: 

$('h2').each(function(index, element) {
    $(this).attr('id', 'anid' + index);
});

You may use an implicit function inside jQuerys .each() like this

var id = 0;
$('h2').each(function(){
    $(this).attr("id", "rev" + id);
    id++;
})

.each() loops through all result array elements, while this reffers always to the current element.
