Page({
data: {
imgUrls: imgUrls,
autoplay: true,//是否自动切换
indicatorDots: true,//是否显示圆点
interval: 5000,//自动切换间隔
duration: 500, //滑动动画时长
indicatorColor: "blue",//滑动圆点颜色
indicatorActiveColor: "white", //当前圆点颜色
current: 2, //当前所在页面的 index
circular: true //是否采用衔接滑动
//其中只可放置<swiper-item/>组件,否则会导致未定义的行为。
}, imageLoad: function () {
//bindload 图片加载的时候自动设定宽度
this.setData({

console.log("current 改变时会触发 change 事件")
