Java脚本延迟加载图像无法在GitHub网站上运行

Question

我正在尝试将图像延迟加载到GitHub网站上。当我在桌面上而不是在GitHub网站上运行HTML文件时，便能够加载这些图像。我已经查看了其他问题，例如Javascript file not working on github pages，但这仅用于来自HTTPS的请求。 谁能帮我吗？

// JavaScript Document
document.addEventListener("DOMContentLoaded", function() {
  var lazyImages = [].slice.call(document.querySelectorAll("img.Images"));

  if ("IntersectionObserver" in window) {
    let lazyImageObserver = new IntersectionObserver(function(entries, observer) {
      entries.forEach(function(entry) {
        if (entry.isIntersecting) {
          let lazyImage = entry.target;
          lazyImage.src = lazyImage.dataset.src;
          lazyImage.srcset = lazyImage.dataset.srcset;
          lazyImage.classList.remove("Images");
          lazyImageObserver.unobserve(lazyImage);
		  lazyImage.classList.add("LazyImages");
        }
      });
    });

    lazyImages.forEach(function(lazyImage) {
      lazyImageObserver.observe(lazyImage);
    });
  } else {
    // Possibly fall back to a more compatible method here
  }
});

.Images {
	width: 280px;
	height: 280px;
	padding: 10px;
	object-fit: cover;
}
.LazyImages {
	width: 280px;
	height: 280px;
	padding: 10px;
	object-fit: cover;
}
