parseInt不工作并将值视为字符串

This is what I currently have:

这就是我目前拥有的:

var typeOrder = ['Land', 'Planeswalker', 'Creature', 'Instant', 'Sorcery', 'Enchantment', 'Artifact', 'Vanguard', 'Plane', 'Scheme', 'Summon', 'Tribal', 'Conspiracy', 'Phenomenon'];

$.each(typeOrder, function (_, order) {
    var cardQuantity = 0;
    var $sorted = $('<div>');

    // sort by types
    var $types = $('.card-line .types').filter(function () {
        return $(this).text() === '["'+order+'"]';
    });

    // title
    if($types.length !== 0) {
        cardQuantity += parseInt($types.siblings('.quantity').text(), 10); // quantity
        $sorted.prepend('<div class="title-gap"></div><h1>' + order + ' ('+ cardQuantity + ')</h1>');
    }

    $('#mainboard').append($sorted);
});
