swiper step Detailed explanation

This time I will bring you a detailed explanation of the steps for swiper operation pictures. What are the precautions for swiper operation pictures? The following is a practical case, let's take a look.

1. Structure

<swiper indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}" indicator-active-color="{{bg}}" style=&#39;height:{{Height}}&#39;>
   <block wx:for="{{imgUrls}}">
    <swiper-item>
      <image src="{{item}}" class="slide-image" mode="widthFix" bindload=&#39;imgHeight&#39;/>  //bindload是绑定图片加载的事件,记得给image加上mode=“widthFix”这个属性哦,还有就是设置这个image 100%宽度哟
    </swiper-item>
   </block>
</swiper>
Copy after login

The various attributes of swiper are available in the official documents and will not be explained here. The most important thing is: style='height:{{Height}}' //Dynamicly set the height of the swiper

2. In the page:

data: {
  imgUrls: [          
    '../img/goodsDetail/goods.png',
    '../img/goodsDetail/goods.png',
    '../img/goodsDetail/goods.png'
  ],
  indicatorDots: true,
  autoplay: true,
  interval: 5000,
  duration: 1300,
  bg: '#C79C77',
  Height:""     //这是swiper要动态设置的高度属性
 },
imgHeight:function(e){
  var winWid = wx.getSystemInfoSync().windowWidth; //获取当前屏幕的宽度
  var imgh=e.detail.height;//图片高度
  var imgw=e.detail.width;//图片宽度
  var swiperH=winWid*imgh/imgw + "px"//等比设置swiper的高度。 即 屏幕宽度 / swiper高度 = 图片宽度 / 图片高度  ==》swiper高度 = 屏幕宽度 * 图片高度 / 图片宽度
  this.setData({
    Height:swiperH//设置高度
  })
},
Copy after login

Summary: Get the current screen width: wx .getSystemInfoSync().windowWidth

Dynamic setting of attributes in the mini program can only be set through setData({ }), which is a bit similar to directly operating css styles in js

Note: if image There is a container in the outer layer, and then after the width of the image is set to 100%, it is a little distance from the bottom of the container where it is placed. That is because the image has the display:inline-block attribute set by default. This attribute will Create a gap. If you want to fill the container, just set it to display:block.
