关于小程序swiper不显示图的那些事

Posted 2020-08-28

还有几天快过年了，在这里提前祝大家新年快乐！

今天没事研究了一下小程序，想整个轮播图玩玩，然后开始看看文档https://mp.weixin.qq.com/debug/wxadoc/dev/component/swiper.html?t=20161107（官网地址）

示例代码

index.wxml

<view class="container">

<swiper indicator-dots="{{indicatorDots}}"

  autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}">
  <block wx:for="{{imgUrls}}">
    <swiper-item>
      <image src="{{item}}" class="slide-image" width="355" height="150"/>
    </swiper-item>
  </block>
</swiper>
<button bindtap="changeIndicatorDots"> indicator-dots </button>
<button bindtap="changeAutoplay"> autoplay </button>
<slider bindchange="intervalChange" show-value min="500" max="2000"/> interval
<slider bindchange="durationChange" show-value min="1000" max="10000"/> duration
</view>

index.js

Page({
  data: {
    imgUrls: [
      ‘http://img02.tooopen.com/images/20150928/tooopen_sy_143912755726.jpg‘,
      ‘http://img06.tooopen.com/images/20160818/tooopen_sy_175866434296.jpg‘,
      ‘http://img06.tooopen.com/images/20160818/tooopen_sy_175833047715.jpg‘
    ],
    indicatorDots: false,
    autoplay: false,
    interval: 5000,
    duration: 1000
  },
  changeIndicatorDots: function(e) {
    this.setData({
      indicatorDots: !this.data.indicatorDots
    })
  },
  changeAutoplay: function(e) {
    this.setData({
      autoplay: !this.data.autoplay
    })
  },
  intervalChange: function(e) {
    this.setData({
      interval: e.detail.value
    })
  },
  durationChange: function(e) {
    this.setData({
      duration: e.detail.value
    })
  }
})

代码贴好了，开始保存运行！咦？图片呢？然后初步怀疑是不是图片地址不能用了，果断试了下，没问题呀！
最后才知道原来是index.wxml中container的app.wxss搞的鬼 align-items: center;这句话删除了，保存运行。这才看到了结果。
