You have an issue with the scope of your map variable. I have posted an example that fixes your code here: <a href="http://jsfiddle.net/XwbsU/3/" rel="noreferrer">http://jsfiddle.net/XwbsU/3/</a>

You should receive the browser geolocation popup when you click 'Find me!'.

Hopefully that helps you.

Here is a quick hack. I recommend this plugin <a href="https://github.com/domoritz/leaflet-locatecontrol" rel="noreferrer">https://github.com/domoritz/leaflet-locatecontrol</a>

<pre><code>var loadMap = function (id) {
 var HELSINKI = [60.1708, 24.9375];
 var map = L.map(id);
 var tile_url = 'http://{s}.tile.osm.org/{z}/{x}/{y}.png';
 var layer = L.tileLayer(tile_url, {
 attribution: 'OSM'
 });
 map.addLayer(layer);
 map.setView(HELSINKI, 19);

 map.locate({setView: true, watch: true}) /* This will return map so you can do chaining */
 .on('locationfound', function(e){
 var marker = L.marker([e.latitude, e.longitude]).bindPopup('Your are here :)');
 var circle = L.circle([e.latitude, e.longitude], e.accuracy/2, {
 weight: 1,
 color: 'blue',
 fillColor: '#cacaca',
 fillOpacity: 0.2
 });
 map.addLayer(marker);
 map.addLayer(circle);
 })
 .on('locationerror', function(e){
 console.log(e);
 alert("Location access denied.");
 });
};

loadMap('map');
</code></pre>

blocks|key|2507664|text|或者，您可以将所有代码放在getLocation()函数下，并在加载网页时调用该函数，这样就完成了所有的设置。我使用这种方法，一旦浏览器加载，它就会弹出一个问题来共享数据。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2507665|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

alternatively you can put all your code under getLocation() function and call that function at the loading of the webpage and you should be all set. I used this way and as soon as browser loads it popups a question to share data.

I'm trying to locate a user and set the map to this position with leaflet:

<pre><code> &lt;script&gt;
 var map;

 function initMap(){
 map = new L.Map('map',{zoomControl : false});
 var osmUrl = 'http://{s}.tile.openstreetmap.org/mapnik_tiles/{z}/{x}/{y}.png',
 osmAttribution = 'Map data &amp;copy; 2012 OpenStreetMap contributors',
 osm = new L.TileLayer(osmUrl, {maxZoom: 18, attribution: osmAttribution});
 map.setView(new L.LatLng(51.930156,7.189230), 7).addLayer(osm);
 }

 function locateUser(){
 map.locate({setView : true});
 }
&lt;/script&gt;
</code></pre>

On execute the browser ask for permission, but then nothing happens? What's wrong with my code?
