可以在每个point上添加一个点击事件,触发事件时改变对应的图片的opacity属性值即可完成图片的切换。具体的实现方式如下:
1. 在每个point元素上添加一个data-index属性,表示对应的图片的索引值,例如:
```html
<ul class="Pictureul2">
<li class="point2" data-index="1">1</li>
<li class="point2" data-index="2">2</li>
<li class="point2" data-index="3">3</li>
</ul>
```
2. 在JavaScript中获取所有point元素,并为其添加点击事件,示例如下:
```javascript
const points = document.querySelectorAll('.point2');
const pictures = document.querySelectorAll('.Pictureul .pli');
points.forEach((point) => {
point.addEventListener('click', () => {
const index = point.dataset.index;
pictures.forEach((picture) => {
picture.style.opacity = 0;
});
pictures[index - 1].style.opacity = 1;
});
});
```
其中,通过获取点击的point元素的data-index属性值来获取对应的图片的索引值,然后将所有图片的opacity属性值设置为0,再将对应索引值的图片的opacity属性值设置为1即可完成图片的切换。
