// 获取所有的图片元素
var lightboxImages = document.getElementsByClassName("lightbox");

// 获取放大图片和关闭按钮元素
var lightbox = document.getElementById("lightbox");
var lightboxImage = document.getElementById("lightbox-image");
var closeButton = document.getElementById("close-button");

// 绑定点击事件，显示放大图片
for (var i = 0; i < lightboxImages.length; i++) {
    lightboxImages[i].addEventListener("click", function() {
        var imageSource = this.getAttribute("src");
        lightboxImage.setAttribute("src", imageSource);
        lightbox.classList.remove("hidden");
    });
}

// 绑定点击事件，隐藏放大图片
closeButton.addEventListener("click", function() {
    lightbox.classList.add("hidden");
