    swiper组件

 

 

一、swiper组件

  indicator-dots:是否显示面板指示点【默认值false】

  autoplay:是否自动切换【默认值false】

  interval:自动切换时间间隔【默认值5000】

  duration:滑动动画时长【默认值500】

 

  swiper滑块组件代码,初始化indicator-dots,autoplay,interval,duration四个属性

<swiper
  indicator-dots="{{indicatorDots}}"
  autoplay="{{autoplay}}"
  interval="{{interval}}"
  duration="{{duration}}"
>
  <block wx:for="{{imgUrls}}" wx:key="">
    <swiper-item>
      <image src="{{item}}" class="slide-image" width="355" height="150" />
    </swiper-item>
  </block>
</swiper>

 

  添加<button>组件绑定函数,去修改indicator-dots,autoplay,interval,duration四个属性

<button bindtap="changeIndicatorDots">indicator-dots</button>
<button bindtap="changeAutoplay">autoplay</button>
interval自动切换时间间隔
<slider bindchange="intervalChange" show-value min="500" max="2000" />
duration滑动动画时长
<slider bindchange="durationChange" show-value min="1000" max="10000" />
