  <view wx:if="{{latitude !=''}}">
    <view>纬度:{{latitude}}view>
    <view>经度:{{longitude}}view>
    <view>速度:{{speed}}view>
    <view>位置的精确度:{{accuracy}}view>
    <view>高度:{{altitude}}view>
    <view>垂直精度:{{accuracy}}view>
    <view>水平精度:{{accuracy}}view>
  view>

const app = getApp()

Page({
  data: {
    latitude: '',

    speed: '',
    accuracy: '',
    altitude:'',
    verticalAccuracy: '',
    horizontalAccuracy:''
  },

  onLoad: function () {

  getLocation:function(){
    var _this=this;
    wx.getLocation({
      type: 'wgs84',
      success: function (res) {
        var latitude = res.latitude
        var longitude = res.longitude
        var speed = res.speed
        var accuracy = res.accuracy
        var altitude = res.altitude
        var verticalAccuracy = res.verticalAccuracy
        var horizontalAccuracy = res.horizontalAccuracy
        _this.setData({
          latitude: latitude,
          longitude: longitude,
          speed: speed,
          accuracy: accuracy,
          altitude: altitude,
          verticalAccuracy: verticalAccuracy,
