<view class="device {{swiperIndex == index ?'active':''}}" data-currentTab="{{index}}">
<view class='device-img'>
<image src='{{device.deviceImg}}'></image>
</view>
</view>
</swiper-item>
</block>
</swiper>
index.js
Page({

},
{
deviceImg: "../../img/2.jpg"
},
{
deviceImg: "../../img/3.jpg"
}
],
},
swiper: function (e) {
let that = this;
let index = e.detail.current;
that.setData({
swiperIndex: index
});
}
})
index.wss
/* 轮播图 */
