微信小程序3D轮播图
作者:互联网
一、最终效果
二、利用原生swiper制作3D效果
1、需要注意的几个API
previous-margin:说白了就是前一张图片能露多少。
next-margin:说白了就是后一张图片能露多少。
circular:这个属性也是需要加的,加不加什么区别,一对比就知道。
2、上代码
wxml
<view class="swiper_wrapper">
<swiper
autoplay
indicator-dots
indicator-color="#8FA2EF"
indicator-active-color="#2F54EB"
class="swiper_two"
previous-margin="150rpx"
next-margin="150rpx"
circular
bindchange="handleChangeTwo">
<block wx:for="{{swiperTwoInfo}}" wx:key="key">
<swiper-item class="item">
<image mode="aspectFit" class="swiper_two_img {{currentIndex4 == index ? 'active' : ''}}" src="{{item.imgSrc}}" />
</swiper-item>
</block>
</swiper>
</view>
wxss
.swiper_wrapper{
margin-bottom: 34rpx;
}
.swiper_two{
width: 100%;
height: 500rpx;
}
.swiper_two_img{
width: 100%;
display: block;
//重点是以下三句
transform: scale(0.8);
transition: all 0.3s ease;
border-radius: 6px;
}
.active{
transform: scale(1);
}
js
现在data中定义当前图片的索引:
data:{
// 轮播图二当前突出图片索引
currentIndex4: 0,
swiperTwoInfo:[
{
key:'21',
imgSrc:'../../../static/imgs/department_introduce/achievements_summary/swiper_two.png'
},
{
key:'22',
imgSrc:'../../../static/imgs/department_introduce/achievements_summary/swiper_two.png'
},
{
key:'233',
imgSrc:'../../../static/imgs/department_introduce/achievements_summary/swiper_two.png'
},
],
}
其次是swiper的change事件处理函数;
/* 实现控制中间凸显图片的样式 */
handleChangeTwo: function(e) {
this.setData({
currentIndex4: e.detail.current
})
},
