<block wx:for-items="{{newGoods}}" wx:key="id">
            <view  catchtap="catchTapCategory" data-goodsid="{{item.id}}">
              <view>
                <image src="{{item.imgUrl}}" /> 
              </view>
              <view class="product-name">
                {{item.name}}           
              </view>
</view>
</block>

catchTapCategory: function (e) {
    var that = this;
    var goodsId = e.currentTarget.dataset.goodsid;
    console.log('goodsId:' + goodsId);    
    wx.navigateTo({ url: '../detail/detail?goodsId=' + goodsId })
