jQuery equal height responsive div rows

Question

I know this question has been asked a million times but i\'m looking for something more specific.

As my site is fully responsive I need the divs to be resized based

I took dclawson's excellent answer and made some edits so it works in other situations, particularly with nested elements as is commen in bootstrap rows.

$.fn.resEqHeight = function(options) {
    var defaults = {
        child: false
    };
    var options = $.extend(defaults, options);

    var $el = $(this);
    if ($el.length > 0) {
        if(!$el.data('resEqHeight')) {
            $(window).bind('resize.resEqHeight', function () {
                $el.resEqHeight(options);
            });
            $el.data('resEqHeight', true);
        }
    } else {
        console.log("No items found for resEqHeight.");
    }

    if( options.child && options.child.length > 0 ){
        var elmtns = $(options.child, this);
    } else {
        var elmtns = $(this).children();
    }

    var prevTop = 0;
    var max_height = 0;
    var elements = [];
    elmtns
        .height('auto')
        .each(function() { $(this).data('resEqHeight.top', $(this).offset().top ); })
        .each(function(index) {
            var $el2 = $(this);
            var thisTop = $el2.data('resEqHeight.top');

            if (index > 0 && prevTop != thisTop) {
                $(elements).height(max_height);
                max_height = $el2.height();
                elements = [];
            }
            max_height = Math.max(max_height, $el2.height());

            prevTop = thisTop;
            elements.push(this);
        });

    $(elements).height(max_height);
};

It works with the same syntax

$('.equalheight').resEqHeight();
$('.equalheight-frame').resEqHeight({child:'.frame'});
