您需要绑定到spin事件以获取输入的值，然后相应地更新DOM

function quantity(price, multiplier) {
    if (multiplier === 1) {
        return '$' + price.toFixed(2);
    }

    return '$' + (price * multiplier).toFixed(2);
}

$( ".spinner" ).spinner({
    min: 1,
    spin: function (event, ui) {
        var value = ui.value;
        var $target = $(event.target);
        var $priceCell = $target.parents('td').next('td');
        var $subtotalCell = $priceCell.next('td');
        $subtotalCell.text(quantity($priceCell.data('price'), value));
    }
});
