微信小程序callout自定义气泡

callout呢，是在标记的点上面显示 一个 气泡，作为提示用

最后展示下 效果 可以展示 顶部气泡以及监听被点击。

废话不多说，直接上代码

wxml

<map id="map" scale="{{scale}}" bindcontroltap="controltap" markers="{{markers}}" bindmarkertap="markertap"
latitude="{{latitude}}" bindcallouttap = "bindcallouttap"
longitude ="{{longitude}}"
controls="{{controls}}" show-location bindregionchange="regionchange" style="width: 100%; height: {{view.Height}}px;"></map>

js

var app = getApp();
