大家好

我在做小程序地图标注的时候，
用makers在开发工具里能够全部展示，
但是通过手机去预览程序，
发现标注的点全不在地图上，
大家知道这个是什么原因吗，
代码如下：
Page({
  data: {
    markers: [],
    scale: 14,
  },
  onShow: function () {
    var that = this
    console.log('onShow')
    //var that = this
    var checkTimer = setInterval(function () {
      var markerArray = []
      wx.request({
        url: 'XXXXXXXXXXXXXXXXXX',
        header: {//请求头
          "Content-Type": "applciation/json"
        },
        method: "GET",
        success: function (res) {

          var busArr = res.data.localist

          for (var i = 0; i < busArr.length; i++) {
            var busLat = res.data.localist[i].la
            var busLong = res.data.localist[i].lo
            var id = Number(res.data.localist[i].id)
            var marker = {
              latitude: busLat,
              longitude: busLong,
              iconPath: "../../images/my.png",
              id: id,
              width: 20,
              height: 40
            }
          markerArray.push(marker)
          }
          that.setData({
            markers: markerArray
          })
        },
        complete: function () {
          console.log("请求complete")
          setTimeout(function () {
            wx.hideToast()
          })
        }
      })
    }, 3000)
  },
 
})
