Limit values displayed in jquery

Question

How do I "limit the amount of values ordered by go below?

I tried to create an array with the Divs and change the display property.. but it does not take the order of the elements..

Much of this code was taken from a previous topic.

// Seleciona as divs que queremos ordenar
var divs = document.querySelectorAll('#res .alqb');

// Converte a NodeList de divs para array

var ordem = [].map.call(divs, function(element) {
    return element;

});

// Ordena a array pelo atributo 'value'
ordem.sort(function(a,b) {
    var ca = parseInt(a.getAttribute('value'), 10);
    var cb = parseInt(b.getAttribute('value'), 10);
    return cb - ca;
});


// Reinsere os filhos no pai, resultando na ordem desejada
var container = document.querySelector('#res');
for(var i=0; i<ordem.length; i++) {
    container.appendChild(ordem[i]); 
}

qtdjogo();
}
