Question

I want to merge recursively arrays..

My code is:

var allitemorder;
var itemorder;

$('.divclass').each(function () {
      itemorder = $(this).sortable('toArray');
      allitemorder = $.merge([], itemorder);
});

Kindly help.

You need just a slight change, like this:

var allitemorder = [], itemorder;

$('.divclass').each(function () {
    itemorder = $(this).sortable('toArray');
    $.merge(allitemorder, itemorder);
});

Or the shorter:

var allitemorder = [];    
$('.divclass').each(function () {
    $.merge(allitemorder, $(this).sortable('toArray'));
});

$.merge(first, second) takes the elements from the second array and puts them in the first, so you need to pass the array you want to accumulate into as the first argument each time.
