Hi there,
I'm actually developing a map using the new google maps API (v3),
which I read is thought to be optimized for better performances..
I'm trying to display approximatively 900 markers on the map,
retrieving data from a json callback, and it takes a very long time
(around 20 seconds)..
this is how I create the markers (that seems to be adherent to how it
is explained in the documentation):
myapp.setMarkerSmall= function(amap) {
//Loop begins ;
for (var i = 0; i < myapp.data.results.length; i++) {
var image = new google.maps.MarkerImage('http://
www.moncalvomarco.it/map/small.gif' , new google.maps.Size(4, 4), new
google.maps.Point(0,0), new google.maps.Point(0, 0));
var shape = { coord: [4,4],type: 'poly'};
var spot = myapp.data.results[i];
var myLatLng = new google.maps.LatLng(spot[5], spot[6]);
var content = spot[4];
myapp.smallmarkers[i] = new google.maps.Marker({
position: myLatLng,
map: amap,
icon: image,
flat: true,
title: spot[4],
zIndex: spot[3],
});
// From zoom=1 (small markers are visible) the function zooms to 3 and
pan to the marker latlng
pantolatlng = function(alatlng){
return function(e){
myapp.deletetMarkers(myapp.smallmarkers);
myapp.map.set_zoom(myapp.map.getZoom() + 1);
myapp.map.panTo(alatlng);
//console.log(acontent);
}
}
//click event handler for smallmarkers
google.maps.event.addListener(myapp.smallmarkers[i], 'click',
pantolatlng(myLatLng)
);
//loop ends
};
// myapp.setMarkerSmall ends
}
I'm new to this group and development in general, and it's is probable
I could code this better..
Is there any reference or real world example any of you can provide,
to help me decreasing loading time (displaying 50-60 markers makes the
map work fine)..
Thank you so much.
M.
