I am trying to create marker categories and display markers on click...
For example, "Eat", "Banks", "Places of Interest" and clicking on them would produce only the markers in those categories. You can see it live HERE
Here is a code snippet:
//<![CDATA[
//<![CDATA[
var map = null;
var gmarkers = [];
var gicons = [];
var icon = [];
function initialize() {
var myOptions = {
zoom: 13,
center: new google.maps.LatLng(37.979183,-121.302381),
mapTypeControl: true,
mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU},
navigationControl: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
// Add markers to the map
// Set up three markers with info windows
///////////////////////// EATS //////////////////////////////////////////////
var point = new google.maps.LatLng(37.988012,-121.311901);
var image = 'icons/orangepointer.png';
var marker = createMarker(point,'<div style="width:205"><center><img src="icons/tigeryogurt.jpg" /></center><br><b>Tiger Yogurt</b><small><br>4343 Pacific Avenue<br>209.952.6042<br><br><a href="http://maps.google.com/maps?saddr=&daddr=' + point.toUrlValue() + '" target ="_blank">Get Directions<\/a></small><\/div>', image);
// this will be gmarkers[0]
var point = new google.maps.LatLng(37.987054,-121.311655);
var image = 'icons/orangepointer.png';
var marker = createMarker(point,'<div style="width:205"><center><img src="icons/mwbakery.jpg" /></center><br><b>M&W Bakery<br>Cakes & Sandwiches</b><small><br>4343 Pacific Avenue<br>209.473.3828<br><br>On the web visit:<br><a href="http://www.mandwdutchamericanbakery.com" target ="_blank">MandWDutchAmericanBakery.com<\/a><br><br><a href="http://maps.google.com/maps?saddr=&daddr=' + point.toUrlValue() + '" target ="_blank">Get Directions<\/a></small><\/div>', image);
// this will be gmarkers[1]
Currently, all markers display. I can easily get the markers not to display... however, i am trying to have only categories display and individual listings to display on click only!
CREATE MARKER FUNCTION:
}
var infowindow = new google.maps.InfoWindow(
{
size: new google.maps.Size(150,50)
});
function triggerClick(i) {
google.maps.event.trigger(gmarkers[i],"click")
};
function createMarker(latlng, html, img) {
var contentString = html;
var marker = new google.maps.Marker({
position: latlng,
map: map,
icon: img,
zIndex: Math.round(latlng.lat()*-100000)<<5
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map,marker);
});
gmarkers.push(marker);
}
I would think the simplest way to do it would be to assign your markers to arrays, with each marker upon creation having setMarker(null). You'd either use a separate array for each category, or a single array of objects each with a category attribute. Then when the user clicks on a category you would iterate through the appropriate array and setMarker(map) for each of its markers.

I am making an aspx page to track vehicles. The only thing I am sticking with is that I don't know how to remove tooltip text from google markers.
The data is displaying correctly.
In the image above, (1) is being shown when I am taking my cursor on marker image and (2) is coming when I am clicking on the marker.
I want to hide (1). How to do that?
I am using the following code:
function initMap() {
var image = '../images/FireTruck.png';
var markers = JSON.parse('<%=ConvertDataTabletoString() %>');
var mapOptions = {
center: new google.maps.LatLng(markers[0].lat, markers[0].lng),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var infoWindow = new google.maps.InfoWindow();
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
for (i = 0; i < markers.length; i++) {
var data = markers[i]
var myLatlng = new google.maps.LatLng(data.lat, data.lng);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: data.title,
icon: image
});
(function (marker, data) {
google.maps.event.addListener(marker, "click", function (e) {
infoWindow.setContent(data.title);
infoWindow.open(map, marker);
});
})(marker, data);
}
}
Don't set the title property of the marker (that is what sets the tooltip).
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: data.title, // <<<<<<<<<<<<<<<<<< REMOVE THIS
icon: image
});
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>
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)
(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);
}
} })();
The code I found for this google map seems to work fine but, The initial marker isn't showing up when I load the map. The map is centered on the initial location but with no Marker. I'm using the php to populate the initial Lat and Lon. Also is there a way to remove the old marker once dragged to a new location?

var marker = null;

});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map,marker);
});
google.maps.event.trigger(marker, 'click');
return marker;
}

});
// populate the form fields with lat & lng
formlat = document.getElementById("latbox").value = event.latLng.lat();

The Map-Tag needed to be added. I had someone try help me but, when his answer created more problems he removed his answer and then down voted my question.... Thanks Buddy.. Here is where the Map-Option needed to go.
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
// establish the initial marker/pin
var myMarker = new google.maps.Marker({
position: new google.maps.LatLng(<?=$a1[lat]?>, <?=$a1[lon]?>),
map: map, /// <-------This is what I added and seems to have fixed my problem
draggable: true,
});
I have the next code to retrieve some data from a xml file. The problem is that when I want to refresh the markers, the response that I get is a duplicated marker in the map. How can I update the points without having duplicated markers?
Best regards

Give your markers unique ids (maybe one of your existing attributes is already unique). If the unique id already exists, move that marker to the new location (or just don't add it again),if it doesn't, create a new marker.
If they don't move, you can also avoid duplicates by checking the distance between new markers and all your existing markers, if it is less than a "same marker" threshold (say ~0.1 meters), don't add it again.
There is a problem with your clearOverlays method (getMarkers(null) just calls getMarkers):
// Removes the overlays from the map, but keeps them in the array.
function clearOverlays() {
for (var i=0; i<gmarkers.length; i++)
{
gmarkers[i].setMap(null);
}
}
I'm quite new to Google Maps API 3 and can't figure out the following error: All clicks on my markers open the infowindow on the same marker (bad), but with different text (good).
I'm pulling the data out of wordpress custom meta data into an xml, which i then parse; What makes me wondering is the fact that generating the markers works this way, but adding the listener for the infowindow obviously fails.
Any ideas what's happening here?

Would be grateful for any ideas ...
One thing I notice is that the marker you are creating in createMyMarker is not declared using var marker, so it looks like you are inadvertently creating a global marker reference. Also, it appears that the statement: return marker is actually after the end of your createMyMarker function, although that may just be a typo that was introduced when you set up your code sample in your question.
At any rate, I believe if you change the code in createMyMarker to declare the marker using var marker within that function, it will give you better results.
