onSelect: function (node) {
                var cknodes = $('#regionTree').tree("getChecked");
                for (var i = 0; i < cknodes.length; i++) {

                        $('#regionTree').tree("uncheck", cknodes[i].target);
                    }
                }
                if (node.checked) {
                    $('#regionTree').tree('uncheck', node.target);

                } else {
                    $('#regionTree').tree('check', node.target);
