2.css:
.swiperBox {
height: 6rpx;
width: 100%;
position: absolute;
bottom: 28rpx;
display: flex;
justify-content: center;
}
.swiperBox1 {
height: 100%;
width: 64rpx;
display: inline-block;
background: #849AB4;
margin-left: 16rpx;
}
.swiperBox1.select {
width: 64rpx;
height: 100%;
background:#fff;
border-radius: 3rpx;
display: inline-block;
margin-left: 16rpx;
}
3.js:
swiperChange(event){
this.setData({
current:event.detail.current
})
}
注意:1. selectCurrent 默認為 0 , 根據在自己的需求來決定要不要 (當前頁面有多個模塊,來回切換時需要回到輪播的第一張圖片),在切換后獲取數據時把selectCurrent 設置成默認的值
2. swiper 默認高度為150rpx (當內容不是圖片時,是一些其他東西,高度不確定的時候,需要獲取他的高度) 見另一文章(
