微信小程序swiper禁止用户手动滑动

用 catchtouchmove 事件来截获用户手动滑动事件，这样既解决了禁用用户手动滑动，有解决了有点击按钮不影响使用

wxml

<swiper class='yaohe' vertical='true' circular='true' autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}">
    <block wx:for='{{yaohe}}'>
      <swiper-item catchtouchmove='catchTouchMove'>   
        <block wx:for='{{item}}'>
          <view class='yaohe_item'>
            <view class='yaohe_img'>
              <image src='{{item.goods_icon}}'>image>
            view>
            <view class='yaohe_right'>
              <view class='yaohe_text'>{{item.goods_feature}}view>
              <view class='boss_price'>
                <view class='boss'>{{item.shop_name}}view>
                <view class='price' bindtap='goGoodsDetail' data-shop_goods_id='{{item.shop_goods_id}}'>￥{{item.goods_price}}view>
              view>
            view>
          view>
        block>
      swiper-item>
    block>
  swiper>

重点js

// 截获竖向滑动
  catchTouchMove:function(res){
    return false
  }
