I want to show all markers on google map , but the looping only show the last record. How can fix it?
function initMap() {
for (i = 0; i < markers.length ; i++) {
var location = {lat: markers[i][0], lng: markers[i][1]};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: location
});
var marker = new google.maps.Marker({
position: location,
// prevent the user move the marker
draggable: false,
map: map
});
}
}
You are creating the map each time in the loop. Due to this only the last marker is seen. Move the code of creating the map outside the loop.
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: {lat: markers[0][0], lng: markers[0][1]}
});
for (i = 0; i < markers.length ; i++) {
var location = {lat: markers[i][0], lng: markers[i][1]};
var marker = new google.maps.Marker({
position: location,
// prevent the user move the marker
draggable: false,
map: map
});
}
}
If you want the map to be zoomed in to view all the markers then you can use the LatLngBounds class.

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
});
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?
// global "map" variable
var map = null;
var marker = null;
// popup window for pin, if in use
var infowindow = new google.maps.InfoWindow({
size: new google.maps.Size(150,50)
});
// A function to create the marker and set up the event window function
function createMarker(latlng, name, html) {
var contentString = html;
var marker = new google.maps.Marker({
position: latlng,
map: map,
zIndex: Math.round(latlng.lat()*-100000)<<5
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map,marker);
});
google.maps.event.trigger(marker, 'click');
return marker;
}
function initialize() {
// the location of the initial pin
var myLatlng = new google.maps.LatLng(<?=$a1[lat]?>,<?=$a1[lon]?>);
// create the map
var myOptions = {

}
var myMarker = new google.maps.Marker({
position: new google.maps.LatLng(<?=$a1[lat]?>, <?=$a1[lon]?>),
draggable: true
});
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]?>),
draggable: true
});
// establish the initial div form fields
formlat = document.getElementById("latbox").value = myLatlng.lat();
formlng = document.getElementById("lngbox").value = myLatlng.lng();
// close popup window
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
// removing old markers/pins
google.maps.event.addListener(map, 'click', function(event) {
//call function to create marker
if (marker) {
marker.setMap(null);
marker = null;
}
// Information for popup window if you so chose to have one
marker = createMarker(event.latLng, "name", "<font color=#660000><b><?=$a1[name]?></b><br>"+event.latLng);
var image = '/images/googlepins/pin2.png';
var myLatLng = event.latLng ;
/*
var marker = new google.maps.Marker({
by removing the 'var' subsquent pin placement removes the old pin icon
*/
marker = new google.maps.Marker({
position: myLatLng,
map: map,
icon: image,
title:"Property Location"
});
// populate the form fields with lat & lng
formlat = document.getElementById("latbox").value = event.latLng.lat();
formlng = document.getElementById("lngbox").value = event.latLng.lng();
});
}

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,
});
Hi,
that's normal code at Google
var map;
function initialize()
{
var latLng = new google.maps.LatLng(41.079120183660486, 28.994637246032653);
var mapOptions = {
center: latLng,
zoom: 8,
mapTypeId : google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
var marker = new google.maps.Marker({
position: map.getCenter(),
map: map,
});
google.maps.event.addListener(map, 'click', function (event) {
//map.setZoom(9);
//map.setCenter(marker.getPosition());
});
}google.maps.event.addDomListener(window, 'load', initialize);
and I want to multiply marker from my DB and I can't do it. I searched in site but always result is gray map.
And my code is:
<script type="text/javascript">
var map;
var latLng;
function initialize() {
var mapOptions = {
//center: latLng,
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
var markers = [];
#foreach (var item in Model)
{
#:markers.push("#item.map")
// item.map content coming like this : 41.079120183660486,28.994637246032653
}
for (var i = 0; i < markers.length; i++) {
var marker = new google.maps.Marker({
position: latLng,
map: map,
});
}
//google.maps.event.addListener(map, 'click', function (event) {
// //map.setZoom(9);
// map.setCenter(marker.getPosition());
// //placeMarker(event.latLng);
//});
}
google.maps.event.addDomListener(window, 'load', initialize);
I can't add markers. I think missing a lot of things? I really need your opinion. Thanks
Based on your code, it looks like you're adding markers to the same lat/lng. The code below adds a few markers in a loop.
<script>
var map;
var center = new google.maps.LatLng(39.715, -84.103);
$(document).ready(initialize);
function initialize() {
// Create map
var mapOptions = {
zoom: 10,
center: center,
panControl: false,
zoomControl: true,
mapTypeControl: true,
scaleControl: true,
streetViewControl: true,
overviewMapControl: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map($('#map_canvas')[0], mapOptions);
for (var ii = 0; ii < 5; ii++) {
var lat = center.lat() + (0.1 * ii);
var lng = center.lng() + (0.1 * ii);
var loc = new google.maps.LatLng(lat, lng);
var marker = new google.maps.Marker({
position: loc,
map: map
});
}
}
</script>
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,

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';

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.
Im having some problems with a street view map: http://server.patrikelfstrom.se/johan/fysiosteo/?page_id=118
Sometimes the window gets grey instead of showing the streetview. So my question is; Is there any way to know when the map has finished loading? I guess its treying to render the map before its completly loaded? Thanks
function initialize() {
var myLatlng = new google.maps.LatLng(57.6988062, 11.9683293);
var myOptions = {
zoom: 16,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP,
disableDefaultUI: true
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
animation: google.maps.Animation.DROP,
title:"Fysiosteo"
});
var panoramaOptions = {
position: myLatlng,
addressControl: false,
pov: {
heading: 90,
pitch: 0,
zoom: 0
}
};
var panorama = new google.maps.StreetViewPanorama(document.getElementById("pano"),panoramaOptions);
map.setStreetView(panorama);
google.maps.event.addListener(panorama, 'idle', function() { console.log('done'); });
}
function loadScript() {
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://maps.googleapis.com/maps/api/js?sensor=false&callback=initialize";
document.body.appendChild(script);
}
window.onload = loadScript;
I tried with this code to print "done" to the console when the map has finished loading, but it didnt work. Am i doing it wrong? :)
The answer to your specific question ("Is there any way to know when the map has finished loading?") is: Yes. When a Map object is finished loading, it will trigger an idle event. Documentation of events that a Map object fires can be found at http://code.google.com/apis/maps/documentation/javascript/reference.html#Map.
