小程序 实现两种导航功能

第一种:导航到店

第二种:点击地图标记

小程序map组件用的是腾讯地图,我这里两种方法都是用经纬度来获取定位,先在腾讯地图经纬度查询,查询到后,再修改data里相对应的longitude和latitude就可以了,代码如下

<!--wxml-->

<!--导航到店-->
<view class="item">
    <image class="item_img4" src="../../images/map.png"></image>
    <view class="look">{{map}}</view>
    <button bindtap="getLocationInfo" class="item_dd">{{stop}}</button>
    <view class="right_arrow" bindtap="getLocationInfo"></view>
</view>

 	
<!--显示地图-->
<!--markers 标记点-->
<!--show-location  显示带有方向的当前定位点-->
<!--scale  缩放级别,取值范围为3-20-->
<map class="map" longitude="{{markers[0].longitude}}" latitude="{{markers[0].latitude}}" scale="16" markers="{{markers}}" bindmarkertap="clickMap" data-markers='{{markers[0]}}' show-location></map>
