微信小程序实现锚点定位楼层跳跃的实例

微信小程序实现楼层锚点跳跃，点击不同的锚点进行位置跳跃：

利用：scroll-into-view 来实现

效果图如下：

WXML:

<scroll-view class="content" scroll-into-view="{{toView}}" scroll-y="true" scroll-with-animation="true">
 <view wx:for="{{act_addList}}">
  <view class="address_top" id="{{ 'inToView'+item.id}}">{{item.region}}</view>
  <view wx:for="{{item.city}}">
   <view class="address_bottom">{{item.name}}</view>
  </view>
 </view>
</scroll-view>
<view class="orientation_region">
 <view class="orientation">自动定位</view>
 <block wx:for="{{orientationList}}" >
  <view class="orientation_city" bindtap="scrollToViewFn" data-id="{{item.id}}">{{item.region}}</view>
 </block>
</view>

WXSS:

page{ height: 100%;}
.content{padding-bottom: 20rpx; box-sizing: border-box; height: 100%;}
.location{width: 100%;}
.location_top{height: 76rpx;line-height: 76rpx; background: #f4f4f4;color: #606660;font-size: 28rpx;padding: 0 20rpx;}

.location_img{width: 48rpx;height: 48rpx;position: absolute;right: 20rpx;top: 125rpx;}
.add_city{width: 228rpx;height: 60rpx;line-height: 60rpx; text-align: center; border: 2rpx solid #ebebeb; color: #000000;margin-right: 20rpx; }
.add_citying{width: 228rpx;height: 60rpx;line-height: 60rpx; text-align: center; border: 2rpx solid #09bb07; color: #09bb07;margin-right: 20rpx;}
.orientation{white-space:normal;display: inline-block; width: 55rpx;height:58rpx; color: #999; text-align: center;}
.orientation_region{ width: 55rpx;font-size: 20rpx;position: fixed;top: 220rpx; right: 0rpx;}
.orientation_city{height: 50rpx; line-height: 50rpx;color: #000;text-align: center;}
