好的,以下是一个简单的手动跳转焦点图的Web程序的示例代码:
HTML代码:
```html
<div class="slideshow-container">
<div class="mySlides fade">
<img src="img1.jpg" style="width:100%">
</div>
<div class="mySlides fade">
<img src="img2.jpg" style="width:100%">
</div>
<div class="mySlides fade">
<img src="img3.jpg" style="width:100%">
</div>
<div class="mySlides fade">
<img src="img4.jpg" style="width:100%">
</div>
<a class="prev" onclick="plusSlides(-1)">❮</a>
<a class="next" onclick="plusSlides(1)">❯</a>
<div class="dots-container">
<span class="dot" onclick="currentSlide(1)"></span>
<span class="dot" onclick="currentSlide(2)"></span>
<span class="dot" onclick="currentSlide(3)"></span>
<span class="dot" onclick="currentSlide(4)"></span>
</div>
</div>
```
CSS代码:
```css
.slideshow-container {
max-width: 800px;
position: relative;
margin: auto;
}
.mySlides {
display: none;
}
.prev,
.next {
cursor: pointer;
position: absolute;
top: 50%;
width: auto;
margin-top: -22px;
padding: 16px;
color: white;
font-weight: bold;
font-size: 18px;
transition: 0.6s ease;
border-radius: 0 3px 3px 0;
user-select: none;
}
.next {
right: 0;
border-radius: 3px 0 0 3px;
}
.prev:hover,
.next:hover {
background-color: rgba(0, 0, 0, 0.8);
}
.dots-container {
text-align: center;
margin-top: 20px;
}
.dot {
cursor: pointer;
height: 15px;
width: 15px;
margin: 0 2px;
background-color: #bbb;
border-radius: 50%;
display: inline-block;
transition: background-color 0.6s ease;
}
.active,
.dot:hover {
background-color: #717171;
}
.fade {
-webkit-animation-name: fade;
-webkit-animation-duration: 1.5s;
animation-name: fade;
animation-duration: 1.5s;
}
@-webkit-keyframes fade {
from {
opacity: 0.4;
}
to {
opacity: 1;
}
}
@keyframes fade {
from {
opacity: 0.4;
}
to {
opacity: 1;
}
}
```
JavaScript代码:
```javascript
var slideIndex = 1;
showSlides(slideIndex);
function plusSlides(n) {
showSlides((slideIndex += n));
}
function currentSlide(n) {
showSlides((slideIndex = n));
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("dot");
if (n > slides.length) {
slideIndex = 1;
}
if (n < 1) {
slideIndex = slides.length;
}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex - 1].style.display = "block";
dots[slideIndex - 1].className += " active";
}
```
请注意,此示例代码仅用于演示目的。你需要根据自己的实际情况修改代码,例如更改图像的路径和数量,更改样式等。
此外,你还需要在HTML文件中包含jQuery库,以便使用jQuery库提供的animate()函数来实现动画效果。你可以在HTML文件的<head>标签中添加以下代码来包含jQuery库:
```html
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
```
