我在YouTube上发现了一个弹出式图库教程,我想首先反转屏幕上显示的内容.
从现在起,当用户在他们的浏览器中打开网站时,他们会看到一个图片库预览,可以点击一张图片来查看完整的图片.我想改变这一点,让第一张照片显示完整的图像.
我只是try 重新排序div,因为我不知道从哪里开始实现我的目标.有谁能帮忙吗?先谢谢你.
const images = [...document.querySelectorAll('.image')];
const popup = document.querySelector('.popup');
const closeBtn = document.querySelector('.close-btn');
const imageName = document.querySelector('.image-name');
const largeImage = document.querySelector('.large-image');
const imageIndex = document.querySelector('.index');
const leftArrow = document.querySelector('.left-arrow');
const rightArrow = document.querySelector('.right-arrow');
let index = 0;
images.forEach((item, i) => {
item.addEventListener('click', () => {
updateImage(i);
popup.classList.toggle('active');
})
})
const updateImage = (i) => {
let path = `img/img${i+1}.png`;
largeImage.src = path;
imageName.innerHTML = path;
imageIndex.innerHTML = `0${i+1}`;
index = i;
}
closeBtn.addEventListener('click', () => {
popup.classList.toggle('active');
})
leftArrow.addEventListener('click', () => {
if (index > 0) {
updateImage(index - 1);
}
})
rightArrow.addEventListener('click', () => {
if (index < images.length - 1) {
updateImage(index + 1);
}
})
