小程式開發實現樓層錨點跳躍實例詳解

這篇文章主要介紹了微信小程式實現錨點定位樓層跳躍的實例的相關資料,需要的朋友可以參考下

微信小程式實現樓層錨點跳躍，點擊不同的錨點進行位置跳躍：

利用：scroll-into-view 來實現

效果圖如下：

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="{{ &#39;inToView&#39;+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_bottom{height: 140rpx;line-height: 140rpx;color: #d91f16;font-size: 28rpx;border-top: 2rpx #ebebeb solid; border-bottom: 2rpx #ebebeb solid;padding: 0 20rpx; align-items: center;display: -webkit-flex;} 
.address_top{height: 76rpx;line-height: 76rpx; background: #f4f4f4;color: #999999;font-size: 28rpx;padding: 0 20rpx;} 
.address_bottom{height: 88rpx;line-height: 88rpx; background: #fff;color: #000000;font-size: 32rpx;padding: 0 20rpx; border-bottom: 2rpx #ebebeb solid;margin-left: 20rpx;margin-right: 50rpx; } 
.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;}
