This solution requires jQuery and Underscore. var wnt = {}; wnt.sortList = { asc: function(sList){ sListItems = $(sList).find(‘li’); sListItems = _.sortBy(sListItems, function(item){ return $(item).text(); }); $(sList).html(sListItems); }, desc: function(sList){ sListItems = $(sList).find(‘li’); sListItems = _.sortBy(sListItems, function(item){ return $(item).text(); }).reverse(); $(sList).html(sListItems); } }; wnt.sortToggle = “asc”; $(‘ul’).click(function(){ wnt.sortList[wnt.sortToggle]($(this)); wnt.sortToggle===’asc’ ? wnt.sortToggle=”desc” : wnt.sortToggle=”asc”; }); Fiddle

Underscore.js is a tiny JavaScript utility library that makes working with some of the common data structures used in JavaScript much easier Common Methods _.union(myArray2, myArray3) to concatenate two arrays _.uniq(myArray3) to strip duplicates from array _.zip(myArray, myArray2) to return arrays where the nth value of each array is paired [0, 0], [1, 1], [2, […]
