使用微信小程序实现地图定位功能

<view class="container">
  <map id="map" latitude="{{latitude}}" longitude="{{longitude}}" scale="{{scale}}" bindmarkertap="markertap" markers="{{markers}}" show-location="{{true}}">
  </map>
</view>

Page({
  data: {
    latitude: 0,
    longitude: 0,
    scale: 15,
    markers: []
  },

  onShow: function () {
    wx.getLocation({
      type: 'GCj02',
      success: (res) => {
        this.setData({
          latitude: res.latitude,
          longitude: res.longitude,
          markers: [{
            id: 0,
            latitude: res.latitude,
            longitude: res.longitude,
            iconPath: '/image/location.png',
            width: 30,
            height: 30
          }]
        })
      },
      fail: (res) => {
        wx.showToast({
          title: '定位失败',
          icon: 'none'
        })
      }
    })
  },

  markertap: function (e) {
    // 地图标记被点击事件的处理函数
  }
})
