<!-- 广告展示 -->
<view class="AdView" hidden="{{showAd}}" catchtouchmove="preventMove">
<view class="bg" ></view>
<view class="active active-sport" >
<view class="cancel" bind:tap = "cancelTap" ></view>
<view class="active-content" bind:tap ="activeContent" data-id='2340173092'>
<text>this is ad</text>
<image class="active-img" src ='cloud://international-3bp20.696e-international-3bp20-1300609829/my-image.jpeg' mode="aspectFit"></image>
</view>
</view>
</view>
//事件 catchtouchmove方法主要作用是固定广告防止点击穿透，就是使用弹出广告的后面内容不能上下拉动。其中对应的.js方法可以不做任何处理。此处只能在真机上看到实际效果，在电脑上不能。并且此方法要放到广告view最外层

此处cancel的背景图片只能使用base64或本地。
image 只能是网络或者fieldId上
可以作用CSS3特性，制作动画，制作动画时要注意加上transform之后，才可以增加rotate旋转，skew翻转，scale缩放，translate移动。
