iterate through all levels of tree and sort folders by name

[devnull]

Is it possible to iterate through all levels of a tree and sort folders (branches) by text field ??

I looked through the api for the tree but don't see anything ?

Thanks

The 'sort' method can be extended as below:

Code:

(function($){
	function sortData(target, order){
		order = order || 'asc';
		var rows = $(target).tree('getRoots');
		_sort(rows);
		$(target).tree('loadData', rows);
		function _sort(rows){
			rows.sort(function(r1,r2){
				var sortFunc = function(a,b){
					return a==b ? 0 : (a>b?1:-1);
				};
				return sortFunc(r1.text,r2.text) * (order=='asc'?1:-1);
			});
			for(var i=0; i<rows.length; i++){
				var children = rows[i].children;
				if (children && children.length){
					_sort(children);
				}
			}
		}
	}
	$.extend($.fn.tree.methods, {
		sort: function(jq, order){
			return jq.each(function(){
				sortData(this, order);
			});
		}
	});
})(jQuery);

Usage example:

Code:

$('#tt').tree('sort', 'asc');
$('#tt').tree('sort', 'desc');
