swiper 中点击active的轮播图
时间: 2023-10-06 18:08:09 浏览: 144
如果你想在 swiper 中点击 active 的轮播图,可以使用 Swiper 的回调函数 onSlideChangeEnd,例如:
```javascript
var mySwiper = new Swiper('.swiper-container', {
onSlideChangeEnd: function () {
var activeIndex = mySwiper.activeIndex;
var activeSlide = mySwiper.slides[activeIndex];
// 在这里处理点击 active 轮播图的逻辑
}
});
```
在 onSlideChangeEnd 回调函数中,可以获取当前 active 的索引和对应的 slide 元素,然后在里面处理点击事件的逻辑。

swiper 6实现堆叠轮播图
Swiper是一个流行的JavaScript库,用于创建响应式的触摸滑动幻灯片或轮播图。在Swiper v6版本中,实现堆叠式轮播图通常涉及到以下几个步骤:
1. **引入库**:首先需要在HTML中引入Swiper的CSS和JS文件:
```html
<link rel="stylesheet" href="swiper.min.css">
<script src="swiper.min.js"></script>
```
2. **初始化Swiper实例**:在需要堆叠的容器上添加一个`swiper`的ID,并配置堆叠模式:
```javascript
var swiper = new Swiper('.swiper-container', {
// 堆叠模式:horizontal 或 vertical,这取决于你想要水平还是垂直堆叠
spaceBetween: 0,
// 如果有多层堆叠,可以设置stackEffect,如'Stack'(默认),'Fade'等
stackEffect: 'Stack',
// 堆叠项之间是否可见,默认是true,若设置为false则隐藏堆叠项之间的间隙
observeParents: true,
});
```
3. **样式设置**:你可以通过CSS进一步定制堆叠项的样式、间隔等:
```css
.swiper-slide {
/* 样式 */
}
.swiper-pagination-bullet-active {
/* 鼠标悬停时或当前选中的指示器样式 */
}
```
4. **事件监听**:为了响应用户交互或控制轮播,可以在Swiper实例上添加事件处理程序:
```javascript
swiper.on('slideChangeEnd', function() {
// 某些操作在切换到新一排后触发
});
```
swiper 异形轮播图案例
以下是一个异形轮播图的案例,使用了Swiper库实现:
HTML代码:
```html
<div class="swiper-container">
<div class="swiper-wrapper">
<div class="swiper-slide" style="background-image:url('image1.jpg')"></div>
<div class="swiper-slide" style="background-image:url('image2.jpg')"></div>
<div class="swiper-slide" style="background-image:url('image3.jpg')"></div>
<div class="swiper-slide" style="background-image:url('image4.jpg')"></div>
<div class="swiper-slide" style="background-image:url('image5.jpg')"></div>
<div class="swiper-slide" style="background-image:url('image6.jpg')"></div>
<div class="swiper-slide" style="background-image:url('image7.jpg')"></div>
<div class="swiper-slide" style="background-image:url('image8.jpg')"></div>
</div>
<div class="swiper-pagination"></div>
</div>
```
CSS代码:
```css
.swiper-container {
width: 100%;
height: 500px;
margin: 0 auto;
position: relative;
overflow: hidden;
}
.swiper-slide {
width: 50%;
height: 100%;
background-size: cover;
background-position: center;
position: absolute;
top: 0;
left: 0;
transition: transform 0.5s ease-in-out;
}
.swiper-slide:nth-child(1) {
transform: translateX(0);
}
.swiper-slide:nth-child(2) {
transform: translateX(50%);
}
.swiper-slide:nth-child(3) {
transform: translateX(100%);
}
.swiper-slide:nth-child(4) {
transform: translateX(150%);
}
.swiper-slide:nth-child(5) {
transform: translateX(200%);
}
.swiper-slide:nth-child(6) {
transform: translateX(250%);
}
.swiper-slide:nth-child(7) {
transform: translateX(300%);
}
.swiper-slide:nth-child(8) {
transform: translateX(350%);
}
.swiper-pagination {
position: absolute;
bottom: 20px;
left: 50%;
transform: translateX(-50%);
z-index: 10;
}
.swiper-pagination-bullet {
width: 10px;
height: 10px;
border-radius: 50%;
background-color: rgba(255, 255, 255, 0.5);
margin: 0 10px;
cursor: pointer;
}
.swiper-pagination-bullet-active {
background-color: #fff;
}
```
JavaScript代码:
```javascript
var swiper = new Swiper('.swiper-container', {
slidesPerView: 'auto',
centeredSlides: true,
spaceBetween: 30,
pagination: {
el: '.swiper-pagination',
clickable: true,
},
on: {
slideChangeTransitionEnd: function() {
var activeIndex = this.activeIndex;
var slidesLength = this.slides.length;
var halfSlidesLength = Math.floor(slidesLength / 2);
var halfIndex = activeIndex % halfSlidesLength;
var translateX = halfIndex * 50;
var slides = this.slides;
for (var i = 0; i < slidesLength; i++) {
var slide = slides[i];
var slideIndex = slide.getAttribute('data-swiper-slide-index');
var halfSlideIndex = slideIndex % halfSlidesLength;
var zIndex = halfSlidesLength - Math.abs(halfIndex - halfSlideIndex);
slide.style.transform = 'translateX(' + (50 * (slideIndex - activeIndex)) + '%) scale(' + zIndex / halfSlidesLength + ')';
slide.style.zIndex = zIndex;
}
},
},
});
```
以上代码实现了一个基于Swiper的异形轮播图,通过CSS设置每个轮播项的位置以及过渡效果,通过JavaScript实现了轮播项的缩放和层叠效果。同时,通过Swiper的API实现了轮播图的自动轮播和分页器。
