小程序多点地图标记

wxml:

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

js:

var app = getApp();

Page({
  data: {
    url: '',
    listData: [
      {
        "id": 1,

  createMarker(point) {

    let latitude = this.strSub(point.placeLatitude);
    let longitude = point.placeLongitude;
    let marker = {
      iconPath: "/image/tbs.jpg",
      id: point.id || 0,
      name: point.placeName || '',
      title: point.placeName || '',
      latitude: latitude,
      longitude: longitude,
      label: {
        x: -24,
        y: -26,
        content: point.placeName
      },
       30,
      height: 30
    };
    return marker;
  }
})

效果:(开发工具上不能放大缩小，所以其他点看不见，手机可见)
