微信小程式swiper元件實現圖片寬度自適應

微信小程式 圖片寬度自適應的實現

例項程式碼:

wxml 程式碼:

<swiper indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}"> 
  <block wx:for="{{imgUrls}}" wx:key="image"> 
   <swiper-item> 
     <image src="{{item.image}}" model="aspectFit" style="width: {{imageWidth}}px;" bindload="imageLoad" /> 
   </swiper-item> 
  </block> 
</swiper> 
JS 程式碼:
imageLoad: function () { 
  this.setData({ 
   imageWidth: wx.getSystemInfoSync().windowWidth,//圖片寬度 
  
   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,//是否顯示圓點 
  autoplay: true,//自動播放 
  interval: 2000,//間隔時間 
  duration: 1000//監聽滾動和點選事件 
 }) 
}
