I'm working on my first google map, the purpose of the map is to show various markers in one city but the map should be zoomed into the marker which I set within the code.
So far I have everything working as it should but I can't figure out how to zoom to a specific marker, at the minute the maps centers and fits in all the markers. Below is my code:
<script>
jQuery(function($) {
// Asynchronously Load the map API
var script = document.createElement('script');
script.src = ";callback=initialize";
document.body.appendChild(script);
});
function initialize() {
var map;
var bounds = new google.maps.LatLngBounds();
var mapOptions = {
mapTypeId: 'roadmap'
};
// Display a map on the page
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
map.setTilt(45);
// Multiple Markers
var markers = [

- How do you "set the code" in the code? example of linkto functionality – geocodezip Commented May 21, 2014 at 13:34
- According to the documentation you must give your map a center location (required). Now which marker you want your map to center on? – MrUpsidown Commented May 21, 2014 at 14:21

Reset to default 5Set the correct zoom and pass the marker position as below
map.setZoom(17);
map.panTo(currentmarker.position);
Further details can be found here Zoom in to marker google.maps
To center the map on the third marker, you can do this:
push your markers into a global array (gmarkers):
for( i = 0; i < markers.length; i++ ) { var position = new google.maps.LatLng(markers[i][1], markers[i][2]); bounds.extend(position); var iconBase = 'images/'; marker = new google.maps.Marker({ position: position, map: map, title: markers[i][0] /*, icon: iconBase + 'carlisle_icon.png' */ }); gmarkers.push(marker); // Allow each marker to have an info window google.maps.event.addListener(marker, 'click', (function(marker, i) { return function() { infoWindow.setContent(infoWindowContent[i][0]); infoWindow.open(map, marker); } })(marker, i)); // Automatically center the map fitting all markers on the screen map.fitBounds(bounds); }center on the third marker (gmarkers[2]):
var boundsListener = google.maps.event.addListener((map), 'bounds_changed', function(event) { map.setZoom(15); map.setCenter(gmarkers[2].getPosition()); google.maps.event.removeListener(boundsListener); });
working fiddle
Note: both map and the gmarkers array are global variables.
You can try something like this :
map.setCenter(new google.maps.LatLng(53.634976, -113.426110));
