    这是一个创建于 2180 天前的主题,其中的信息可能已经有所发展或是发生改变。

    对小程序知识薄弱,现在实现了 swiper 切换,所有图片地址存在 imgUrls 这个数组当中,然后循环出来。但是我现在想要在每个卡片弄一些文本,滑到不同得卡片显示不同的文本。






    下面是代码:



    index.wxml

    <swiper class="swiper-block" previous-margin="90rpx" next-margin="90rpx" current="0" bindchange="swiperChange">
    <block wx:for="{{imgUrls}}" wx:index="{{index}}">
    <swiper-item class="swiper-item">
    <image mode="aspectFill" src="{{item}}" class="slide-image {{swiperIndex == index ? 'active' : ''}}"/>
    </swiper-item>
    </block>
    
    </swiper>
    



    index.wxss

    .swiper-block{
    height: 1000rpx;
    width: 100%;
    margin-top: 30px;
    }
    
    .swiper-item{
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: flex-start;
    overflow:unset;
    }
    
    .slide-image{
    height:800rpx;
    width: 520rpx;
    border-radius: 9rpx;
    box-shadow: 0px 0px 30rpx rgba(0, 0,0,.2);
    margin: 0rpx 30rpx;
    z-index: 1;
    }
    
    .active{
    transform: scale(1.15);
    transition:all .2s ease-in 0s;
    z-index: 20;
    }
    



    index.js

    Page({
    
      data: {
    
        imgUrls: [
    
          'https://img.mukewang.com/5a72827d0001cb8006000338-240-135.jpg',
          'https://img.mukewang.com/57075b250001044506000338-240-135.jpg',
          'https://img.mukewang.com/5a72827d0001cb8006000338-240-135.jpg',
          'https://img.mukewang.com/5a72827d0001cb8006000338-240-135.jpg',
          'https://img.mukewang.com/5a72827d0001cb8006000338-240-135.jpg'
    
        ],
        indicatorDots: false,
        autoplay: false,
        interval: 5000,
        duration: 1000
      },
    
      swiperChange(e) {
        const that = this;
        that.setData({
          swiperIndex: e.detail.current,
        })
      }
    })
    

    只想增加划到每个卡片显示不同的文本!最好是有单独的 view 去写样式。
