Question

我如何定位正确的.card元素，即使它有点击的子元素？

.card.animate＆lt; - 我想要这个

如果使用currentTarget，它将执行类似这样的操作

wine_content.animate＆lt; - 不是我想要的

或

.card h4.animate＆lt; ---不是我想要的。

编辑：我真的很想做一个for循环和addListener从一个元素数组的每张卡上。这是错的吗？

＆＃13;

var card = document.getElementById('wine_content');
    
    card.addEventListener("click", function (e) {
        if (e.target !== e.currentTarget) {  
          e.target.classList.toggle('animate');
        }
        e.stopPropagation()
    }, false);

在点击监听器中选择closest卡片，您可以选择点击的card - 您可以从以下代码中进行推断。

让我知道您的反馈意见。干杯！

var card = document.getElementById('wine_content');

card.addEventListener("click", function(e) {
  e.stopPropagation();
  var cardElement = closest(e.target, function(el) {
    return el.classList.contains('card');
  });
  if (cardElement)
    cardElement.classList.toggle('animate');
}, false);

// getting the closest in the parent hierarchy
// reference: http://stackoverflow.com/questions/22100853/dom-pure-javascript-solution-to-jquery-closest-implementation
function closest(el, fn) {
  while (el) {
    if (fn(el)) return el;
    el = el.parentNode;
  }
}
