支付宝小程序轮播组件

轮播组件传值有个奇怪现象，就是必须为propArray

axml部分

<view class="swiper-container">
  <swiper indicator-dots="{{indicatorDots}}" interval="{{interval}}" duration="{{duration}}" circular="{{duration}}"
   onChange="swiperChange" class="swiper" autoplay="{{autoplay}}">
    <block a:for="{{propArray}}" a:key="unique">
      <swiper-item>
        <image src="{{item.imgs}}" data-link="{{item.link}}" class="img" onTap="swipclick"  />
      </swiper-item>
    </block>
  </swiper>
  <view class="dots">
    <block a:for="{{propArray}}" a:key="unique">
      <view class="dot{{index == swiperCurrent ? ' active' : ''}}" data-id="{{item.id}}" onTap="chuangEvent"></view>
    </block>
  </view>
</view>
