ios translateMarker 报错invalid markerid
发布于 6 年前 作者 yongdeng 19260 次浏览 来自 问答

使用 mapContext的translateMarker，在调试工具和安卓手机上Marker都可以正常移动到服务器传过来的地理定位，但是ios上就会经常报出errMsg:“translateMapMarker:fail invalid markerid”，偶尔也可以正常显示，一下是部分关键代码，请大神指教一下。

map组件

<map id="mymap" longitude="{{mapLon}}" latitude="{{mapLat}}" markers="{{markers}}" scale="14">
 
map>

markers

markers: [{
 iconPath: '../assets/image/icon_map_location.png',
 id: 0,
 latitude: 0,
 longitude: 0,
 width: 12,
 height: 16
}]

translateMarker

translateMarker (lat, lon) {
 lat = parseFloat(lat)
 lon = parseFloat(lon)
 const self = this
 self.mapCtx = wx.createMapContext('mymap')
 self.mapCtx.translateMarker({
   markerId: 0,
   autoRotate: false,
   duration: 1000,
   destination: {
     latitude: lat,
     longitude: lon
   },
   animationEnd () {
     console.log('animation end')
   },
   fail (err) {
     console.log(err)
   }
 })
}

不清楚为什么会这样 ，但是如果是在chooseLoacation.then里面调用 就有可以正常显示

self.chooseLocation().then(res => {
  self.mapLon = res.longitude
  self.mapLat = res.latitude
  console.log('为空self.mapLon：',self.mapLon)
  self.translateMarker(+res.latitude, +res.longitude)
  self.mapMask.bg = 'rgba(0,0,0,0)'
  self.mapMask.none = 'none'
  self.$apply()
})

ios11 微信6.6.3 为什么从服务器获取经纬度信息，在移动translateMarker会显示 invalid markerid

什么时机调用translateMarker，麻烦提供一下完整一点的代码

@黄思程

    getCardInfo ($id) {
      const self = this
      wepy.request({
        method: api.cardBseInfo.method,
        url: api.cardBseInfo.url,
//      data: {card_id: $id, simple: 1},
        data: {card_id: $id},
        header: {
          token: self.token,
          appname: 'weappInvitationCard'
        }
      }).then(res => {
        let resObj = res.data.data
        let timeArr = resObj.time.split(' ')
        let hoursMin = timeArr[1].substr(0, 5);
        let lat = self.mapLat = resObj.latitude
        let lon = self.mapLon = resObj.longtitude
//        let lat = self.editorPageLat = resObj.latitude
//        let lon = self.editorPageLon = resObj.longtitude
        self.groom_val = resObj.groom_name
        self.bride_val = resObj.bride_name
        self.wed_add_val = resObj.place
        self.front_page_id = resObj.front_page.id
        self.speech_page_id = resObj.speech_page.id
        self.front_page_imgArr = resObj.front_page.images
        self.speech_page_imgArr = resObj.speech_page.images
        console.log(resObj.front_page.images,self.front_page_imgArr)
        self.date = timeArr[0]
        self.time = hoursMin
        self.positionIcon = '16px'
        self.positionIconBlock = 'block'
        self.mapMask.parentNone = 'block'
        self.mapMask.bg = 'rgba(0,0,0,0)'
        self.mapMask.none = 'none'
        self.theme_id = resObj.theme_id
        self.editorCardMode = true
        self.translateMarker(parseFloat(lat), parseFloat(lon))
        self.$apply()
      })
    }
 
    translateMarker (lat, lon) {
      const self = this
      self.mapCtx = wx.createMapContext('mymap')
 
      self.mapCtx.translateMarker({
        markerId: 0,
        autoRotate: false,
        duration: 1000,
        destination: {
          latitude: lat,
          longitude: lon
        },
        animationEnd () {
          console.log('animation end')
        },
        fail (err) {
          console.log('ni ma')
          console.log(err)
        }
      })
    }

不是一直没有，是时有时无，很郁闷
