swiper轮播图

swiper中只能放swiper-item
block 并不是一个组件，它仅仅是一个包装元素，不会在页面中做任何渲染，只接受控制属性。

<swiper indicator-dots="{ {indicatorDots}}" autoplay="{ {autoplay}}" interval="{ {interval}}" duration="{ {duration}}">
  <block wx:for="{ {imgUrls}}">
    <swiper-item>
      <image src="{ {item}}" class="slide-image" />
    </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
.slide-image{ 
  width: 100%;
  height: 100%;
}
