　　　　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" />

<!-- 建立swiper代码块 -->
<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>

<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" />
