swiper通过设置current切换页面，circular衔接效果失效 - WXOPEN Club

<view>
    <swiper circular="{{true}}" current="{{currentTap}}">

data: {

    console.log('点击上一页 newTap:' + newTap + '  currentTap:' + this.data.currentTap)
    this.setData({
        currentTap: newTap
    })

nextBtn: function () {
    let newTap = 0;
 
    if (this.data.currentTap == 0) {
        newTap = 1;
    } else if (this.data.currentTap == 1) {
        newTap = 2;
    } else if (this.data.currentTap == 2) {
        newTap = 0;
    }
    console.log('点击下一页 newTap:' + newTap + '  currentTap:' + this.data.currentTap)
    this.setData({
        currentTap: newTap
    })
},

swiper组件设置circular衔接滑动时，手势左右滑动可达到衔接效果；
但是当通过设置current属性时，一直点击下一页，没有衔接效果；
