以下是一个简单的基于jQuery的轮播图代码:
HTML:
```
<div class="slider">
<div class="slider-container">
<div class="slide">
<img src="image1.jpg" alt="Slide 1">
</div>
<div class="slide">
<img src="image2.jpg" alt="Slide 2">
</div>
<div class="slide">
<img src="image3.jpg" alt="Slide 3">
</div>
</div>
<div class="slider-nav">
<button class="prev">Previous</button>
<button class="next">Next</button>
</div>
</div>
```
CSS:
```
.slider {
position: relative;
width: 100%;
height: 400px;
overflow: hidden;
}
.slider-container {
position: absolute;
top: 0;
left: 0;
width: 300%;
height: 100%;
display: flex;
}
.slide {
width: 33.33%;
display: flex;
align-items: center;
justify-content: center;
}
.slide img {
max-width: 100%;
max-height: 100%;
}
.slider-nav {
position: absolute;
bottom: 20px;
left: 50%;
transform: translateX(-50%);
}
.slider-nav button {
font-size: 18px;
padding: 10px 20px;
border: none;
background-color: #333;
color: #fff;
margin: 0 10px;
}
.slider-nav button:hover {
cursor: pointer;
background-color: #555;
}
```
JavaScript:
```
$(document).ready(function() {
var sliderContainer = $('.slider-container');
var slides = $('.slide');
var slideCount = slides.length;
var slideWidth = 100 / slideCount;
var currentIndex = 0;
sliderContainer.css('width', slideCount * 100 + '%');
slides.css('width', slideWidth + '%');
$('.next').click(function() {
if (currentIndex < slideCount - 1) {
currentIndex++;
sliderContainer.animate({left: -currentIndex * slideWidth + '%'}, 500);
} else {
currentIndex = 0;
sliderContainer.animate({left: 0}, 500);
}
});
$('.prev').click(function() {
if (currentIndex > 0) {
currentIndex--;
sliderContainer.animate({left: -currentIndex * slideWidth + '%'}, 500);
} else {
currentIndex = slideCount - 1;
sliderContainer.animate({left: -currentIndex * slideWidth + '%'}, 500);
}
});
});
```
这是一个基本的轮播图,点击“Previous”和“Next”按钮可以切换图片。你可以根据自己的需求进行修改和扩展。
