javascript - parseInt 不工作并将值视为字符串

Question

这是我目前拥有的:

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);
});

parseInt 在这里似乎不起作用:

cardQuantity += parseInt($types.siblings('.quantity').text(), 10); // quantity

它一直给我像字符串一样的整数。例如，值是 1 + 2，它给了我 12 而不是 3。不确定为什么它不起作用。

在中使用回调函数text() 迭代值的方法

function SortCards() {
  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 + '"]';
    });

    // land sort
    if (order === 'Land') {
      $types.parent().sort(function(a, b) {
        var landTypeA = $(a).find('.supertypes').text();
        var landTypeB = $(b).find('.supertypes').text();

        return (landTypeA == '["Basic"]' && landTypeB != '["Basic"]') ? 0 : (landTypeA != '["Basic"]' && landTypeB == '["Basic"]') ? 1 : -1;
      }).appendTo($sorted);
    }

    // secondary sort by cmc
    $types.parent().sort(function(a, b) {
      var cmcA = +$(a).find('.cmc').text();
      var cmcB = +$(b).find('.cmc').text();

      return cmcA > cmcB ? 1 : (cmcA < cmcB ? 0 : -1);
    }).appendTo($sorted);

    // title
    if ($types.length !== 0) {

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

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

SortCards();
