Solution 1:

Try this,

        $('.jstree-clicked').click();
        if($('.jstree-clicked').closest('.jstree-children').prev('.jstree-anchor').length){
            $('.jstree-clicked').removeClass('.jstree-clicked');
            $('.jstree-clicked').closest('.jstree-children').prev('.jstree-anchor').addClass('.jstree-clicked');
        }
    }
