隐藏了父块
如果该脚本没有加载图像的SRC，则
。除了Firefox

之外，所有浏览器都可以使用这是Firefox错误还是脚本问题？如果问题出现在脚本中，我该如何使其在Firefox中起作用？

PS 。在此站点上看不可见此错误。尝试在本地（不使用Internet）在PC上创建 index.html 文件并在此处粘贴此代码，然后在Firefox中查看结果。

let images = document.querySelectorAll('.Parent_block > .Child_Img');

images.forEach(function(e) {
  e.onerror = function() {
    e.closest('.Parent_block').style.display = 'none';
  };
});

.Parent_block {
  width: 30%;
  margin: 0;
  padding: 0;
  margin-left: 10px;
  margin-top: 10px;
  border: 1px solid black;
  display: inline-block;
  height: 250px;
}

img {
  height: inherit;
  width: 100%;
}

<figure class="Parent_block">
  <img class="Child_Img" src="">
  <figcaption class="Img_text">1</figcaption>
</figure>


<figure class="Parent_block">
  <img class="Child_Img" src="https://i.ibb.co/kyXhZmB/photo-2021-11-18-14-40-18.jpg">
  <figcaption class="Img_text">2</figcaption>
</figure>


<figure class="Parent_block">
  <img class="Child_Img" src="">
  <figcaption class="Img_text">3</figcaption>
</figure>

原文

This script hides the parent block
if it doesn't have the src of the image loaded.
Works in all browsers except Firefox

Is this a Firefox bug or a script issue? If the problem is in the script, how can I make it work in Firefox?

P.S. This error is not visible on this site. Try creating an index.html file locally(without using the internet) on your PC and paste this code there, then view the result in Firefox.

let images = document.querySelectorAll('.Parent_block > .Child_Img');

images.forEach(function(e) {
  e.onerror = function() {
    e.closest('.Parent_block').style.display = 'none';
  };

.Parent_block {
  width: 30%;
  margin: 0;
  padding: 0;
  margin-left: 10px;
  margin-top: 10px;
