从 <img 标记上的自定义属性中获取数据

请检查代码底部的JavaScript代码。我的目标是将所有Data-CC属性值作为一个数组存储在我的变量" Collection"中。我已经做了Code Bellow，但是我缺少的事情根本无法工作。预先感谢

使用 .each()循环扔图像并将值添加到您的数组

请参阅摘要：

var collection = [];
$('[data-cc]').each(function() {
  collection.push($(this).attr('data-cc'));
});
console.log(collection);

  <img src="/images/flags/il.svg" data-cc="b" class="zastavica" />
  <img src="/images/flags/il.svg" data-cc="c" class="zastavica" />
