javascript - Google maps not drawing the map on localhost -

-

am trying first current co-ordinates using navigator.geolocation , use latitude , longitude draw map.

but it's not showing map, blank white screen.

<html> <style type="text/css">         html{height: 100%}         body{height: 100%; margin: 0; padding: 0}         #map-canvas{height: 100%} </style> <script src="https://maps.googleapis.com/maps/api/js?sensor=false"></script> <script> function getlocation() {     if (navigator.geolocation){         navigator.geolocation.getcurrentposition(showposition);     }     else         alert("geolocation not supported browser"); } function showposition(position) {     coord = {};     coord.lat = position.coords.latitude;     coord.longi = position.coords.longitude;     initialize(coord); }  function initialize(coord) {   var map_canvas = document.getelementbyid('map_canvas');   var map_options = {     center: new google.maps.latlng(coord.lat, coord.longi),     zoom:8,     maptypeid: google.maps.maptypeid.roadmap   }   var map = new google.maps.map(map_canvas, map_options); } google.maps.event.adddomlistener(window, 'load', getlocation);   </script> <body> <div id="map_canvas" data-role="page"></div> </body> </html>

i going post http://jsfiddle.net/n5jqpo9u/1/ , don't see problem in code , mine works...

and right before press post button, realized, used map-canvas rather map_canvas css...

- , _ :(

and way, can not location when run file using chrome. if operation timed out , or app has no permission location, display white page too. , should add error handling this:
