Sort the div in alphabetical order using data attribute

You can use String.prototype.localeCompare

JSFIDDLE here

---

var alphabeticallyOrderedDivs = $('.value').sort(function(a, b) {
    return String.prototype.localeCompare.call($(a).data('site').toLowerCase(), $(b).data('site').toLowerCase());
});

var container = $("#aphaOrder");
container.detach().empty().append(alphabeticallyOrderedDivs);
$('body').append(container);

This should work:-

        $("#aphaOrder .value").sort(function (a, b) {
            if ( ($(a).attr("data-site").toLowerCase() > $(b).attr("data-site").toLowerCase()) )  { 
                return 1;
            } else if ( ($(a).attr("data-site").toLowerCase() == $(b).attr("data-site").toLowerCase()) ){
                return 0;
            } else {
                return -1;
            }
        }).each(function () {
            var elem = $(this);
            elem.remove();
            $(elem).appendTo("#aphaOrder");
        });
