微信小程序swiper如何获得当前页面的index

想要实现的效果:(滑动时显示当前页面index)

看小程序的官方文档

代码: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
    })
  },
