Ruby on rails gmaps4rails在刷新时检测位置跳转

我在Rails 3.1.3应用程序中使用gmaps4rails，我在gmaps4rails.base.js.coffee文件中设置了位置检测，如下所示

@default_map_options =
  id: 'map'
  draggable: true
  detect_location: true  # should the browser attempt to use geolocation detection features of HTML5?
  center_on_user: true   # centers map on the location detected through the browser
  center_latitude: 0
  center_longitude: 0
  zoom: 7
  maxZoom: null
  minZoom: 10
  auto_adjust : true      # adjust the map to the markers if set to true
  auto_zoom: true         # zoom given by auto-adjust
  bounds: []              # adjust map to these limits. Should be [{"lat": , "lng": }]
  raw: {}                  # raw json to pass additional options

这种方法有一半的时间有效。我注意到，当我按F5或Ctrl+r刷新浏览器时，它有时会将我置于Broken Hill，而我本应在墨尔本（相差840公里）

有时我看到它很快就去了破山，然后在装货的时候切换到墨尔本。以下是我安装的所有其他插件：

#= require gmaps4rails/gmaps4rails.base
#= require gmaps4rails/gmaps4rails.googlemaps
#= require jquery
#= require jquery_ujs
#= require jquery.ui.datepicker
#= require jquery-ui-timepicker-addon
#= require jquery.ui.autocomplete
#= require jquery.ui.slider
#= require jquery.flexslider
#= require jquery.ui.widget
#= require jquery.ui.mouse
#= require jquery.ui.touch-punch.min
#= require jQuery.BlackAndWhite
#= require form-accordion
#= require modernizr
#= require lovesjavascript
#= require jquery.tokeninput
#= require authentications
#= require inquiries
#= require registrations
#= require search
#= require tinymce-jquery
#= require jquery.sticky
#= require_self

我只尝试过gmaps4rails base和Google地图，但仍然存在问题。

我使用标准的html5地理定位。这有时会失败。酷，我还以为只有我。
