微信小程序 图片宽度自适应的实现
实例代码：
wxml 代码：
<swiper indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}"> <block wx:for="{{imgUrls}}" wx:key="image"> <swiper-item> <image src="https://www.jb51.net/{{item.image}}" model="aspectFit" bindload="imageLoad" /> </swiper-item> </block> </swiper>
JS 代码：
imageLoad: function () { this.setData({ imageWidth: wx.getSystemInfoSync().windowWidth,//图片宽度 imgUrls: [ { image: "http://img02.tooopen.com/images/20150928/tooopen_sy_143912755726.jpg" }, { image: "http://img06.tooopen.com/images/20160818/tooopen_sy_175866434296.jpg" }, { image: "http://img06.tooopen.com/images/20160818/tooopen_sy_175833047715.jpg" }], indicatorDots: false,//是否显示圆点 autoplay: true,//自动播放 interval: 2000,//间隔时间 duration: 1000//监听滚动和点击事件 }) }
