javascript - Client Location Detection Works on Safari Desktop But Not Safari Mobile -

-

i'm trying set client location detection mobile web site using code below:

<html>    <head>    </head>    <body>       <script type="text/javascript" src="http://www.google.com/jsapi"></script>       <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false&libraries=geometry"></script>       <script>          var geocoder = new google.maps.geocoder();          var loc = {};          if(google.loader.clientlocation) {          loc.lat = google.loader.clientlocation.latitude;          loc.lng = google.loader.clientlocation.longitude;          }          var clientlocation = new google.maps.latlng(loc.lat, loc.lng);          alert(clientlocation);       </script>    </body> </html>

this works fine on safari on desktop returns (nan,nan) when run on safari mobile browser. can suggest might going wrong?

i believe above code works.

i tested on iphone 5 using safari, , works okay.

are sure have location services enabled on iphone safari? make sure haven't turned them off.

-
i using tfs's team explorer manage visual studio projects. recently, i've created new java project (not in visual studio) manually added tfs using source control control explorer in visual studio. after added java project tfs, made changes , bug fixes. then, went visual studio , opened source control explorer check in changes, tfs thinks no changes made. it seems needed check out project before making changes. guess erroneously expected tfs track automatically, okay. so, using source control explorer in tfs, checked out project, , tried check in pending changes. when tried check in, got following message: all of changes either unmodified files or locks. changes have been undone server. is there way convince server indeed project has changed? how can check in changes have made? thank help.
