KML file more than 2000 placemarks - google-maps-api-3

Question

I want to import kml files that contains more than 2000 placemarks into googla map.
I use google api v3.
I can only show 200 placemarks.
I know that I can use more layers, but I want only one because I have to refresh it weekly and I don't want to split every time.
Thanks for your replays
THIS IS THE CODE:
<script>
var map;
function initialize() {
var mapOptions = {
zoom: 8,
center: new google.maps.LatLng(47.25,19.5),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
loadKmlLayer(map);
}
function loadKmlLayer(map) {
var ctaLayer2 = new google.maps.KmlLayer('https://.../asdf.kml', {
suppressInfoWindows: false,
preserveViewport: false,
map: map
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>

Answer 1

If your KML isn't very complex, you could try rendering it with a third-party KML parser (geoxml3 or geoxml-v3), see if that works (or points to the problem you are having with KmlLayer)

Answer 2

(function() {
window.onload = function() {
// Creating a new map
var map = new google.maps.Map(document.getElementById("map"), {
center: new google.maps.LatLng(47.10,19.5),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
// Creating the JSON data
var json = [
DATA HERE LIKE:
{"title" :"City ZIP CODE STREET" , "lat" :47.2876 , "lng" :20.4978 ,"description" :"YOUR DESCRIPTION"},
]
// Creating a global infoWindow object that will be reused by all markers
var infoWindow = new google.maps.InfoWindow();
// Looping through the JSON data
for (var i = 0, length = json.length; i < length; i++)
{
var data = json[i],
latLng = new google.maps.LatLng(data.lat, data.lng);
// Creating a marker and putting it on the map
var marker = new google.maps.Marker({
position: latLng,
map: map,
title: data.title,
// icon: iconimage
});
// Creating a closure to retain the correct data, notice how I pass the current data in the loop into the closure (marker, data)
(function(marker, data) {
// Attaching a click event to the current marker
google.maps.event.addListener(marker, "click", function(e) {
infoWindow.setContent(data.description);
infoWindow.open(map, marker);
});
})
//OnClick event
(marker, data);
}
} })();
