javascript добавить условие

Recommended Posts

Ребята приветствую.

Может кто подскажет(я пока в javascript) не силен.

Нужно добавить условие, чтобы при при вводе значения вручную (не только кнопкой "плюс" либо " минус") можно было менять значения

Заранее спасибо.



<script type="text/javascript"><!--
$(document).on('click', '.number-spinner button', function () {    
    var btn = $(this),
        oldValue = btn.closest('.number-spinner').find('input').val().trim(),
        newVal = 1;
    if (btn.attr('data-dir') == 'up') {
        newVal = parseInt(oldValue) + 1;
    } else {
        if (oldValue > 1) {
            newVal = parseInt(oldValue) - 1;
        } else {
            newVal = 1;
