Run min / max over a JQuery object to equalise heights etc.

jquery.minmax.js

/*
	min, max - jQuery plugins which set css properties to min/max value for the collection
	@author	John Hunter
	created	2011-11-03
	use: $('li.tabs').max('height');
*/
(function ($) {

	$.fn.max = function (prop) { return foldProp(this, Math.max, prop); };
	$.fn.min = function (prop) { return foldProp(this, Math.min, prop); };

	function foldProp (el, fn, p) {
		return el.css(p, fn.apply(null, $.map(el, function (v) {
			return parseInt($.css(v, p));
		})));
	};

}(jQuery));

A really simple and flexible solution for the equalHeights plugin. E.g: $('li.tabs').max('height') will make sure all the tabs are the same height.
