Sorting a list alphabetically with a modulus

Question

I don\'t have any trouble grabbing a list of elements and sorting them alphabetically, but I\'m having difficulty understanding how to do it with a modulus.

###

Answer 1

See if this will work: http://jsfiddle.net/6xm9m/2

var newList = new Array();
var listItem = $('#list > li');
var mod = 4;
var colCount = Math.ceil(listItem.length / mod);

listItem.each(function(index) {
    var newIndex = ((index % colCount) * mod) + Math.floor(index / colCount);
    // $(this).text(newIndex);

    newList[newIndex] = this;
});

$('#list').empty();

for(var i = 0; i < newList.length; i++){
    $('#list').append(newList[i]);
}

Needs improvements, probably, but I'm not really sure how well this works at all.
