关于微信小程序map地图的使用
结构部分:
<map id='mymap' bindregionchange='bindregionchange' show-location longitude='{{longitude}}' latitude='{{latitude}}' markers='{{markers}}' class="maps" scale='18' >
<cover-image class='position_img' bindtap='getlocation' src='../images/position.png'></cover-image>
</map>
逻辑部分:
// pages/index/index.js
const app = getApp()
Page({
/**
* 页面的初始数据
*/
data: {
latitude: 22.3434,
longitude: 113.535,
markers: [
{
id: 1,
iconPath: '../images/core1.png',
latitude: 22.3434,
longitude: 113.535,
width: 40,
height: 40
}
],
},
/**
* 生命周期函数--监听页面加载
*/
onLoad: function (options) {
this.getLocationInfo()
console.log(app)
},
/**

*/
onReady: function () {
var that = this
that.mapCtx = wx.createMapContext('mymap')

*/

/**

/**

// 获取用户的位置

// 当视图发生变化时触发
