微信小程序：简单实现地图导航功能实现

微信小程序：简单实现地图导航功能实现

里面的小图片需要自己找，真机调试时，点击导航即可进入地图，可导航，规划路线…

效果图

代码：

wxml

<view class="map_container">
    <map class='map' longitude='{{longitude}}' latitude='{{latitude}}' scale='{{scale}}' markers='{{markers}}' controls="{{controls}}" bindcontroltap="bindcontroltap" polyline='{{polyline}}' circles="{{circles}}" bindmarkertap='bindmarkertap' bindcontroltap='bindcontroltap' show-location >
    map>
view>

<view class='list-guide'>
    
    <view bindtap="onGuideTap" data-latitude='39.92392' data-longitude='116.411885' data-bankName='最高人民检察院'>
        <image src='http://10.3.236.167/images/1.png' class='list-guide-imgae'>image>
        <text class='list-guide-text'>导航text>
