想要實現的效果:(滑動時顯示當前頁面index)
看小程序的官方文檔
代碼:index.wxml
<swiper class='sw-tu' circular="true" current="0" bindchange='onSlideChangeEnd'> <swiper-item class="sw-tuone" wx:for="{{list.img2}}"> <image class='sw-photo' src="{{item}}" /> </swiper-item> </swiper>
index.js
data: {
index: 1,
},
onSlideChangeEnd: function (e) {
var that = this;
that.setData({
index: e.detail.current + 1
})
},
