Can somebody help me put the current location in front of all others? I have read about MAX_ZINDEX and setZindex() but I cannot understand it. This is my code:
var latlng = new google.maps.LatLng(lat,lng);
var image = "";
var currentplace = "Ohla Hotel";
var zInd = "";
if( name == currentplace ) {
image = "../img/hotel_icon.png";
}
else {
image = "../img/home_icon.png";
}
//alert();
var maxZindex = google.maps.Marker.MAX_ZINDEX;
if( name == currentplace ) {
zInd = (maxZindex + 1);
}
var locationDescription = this.locationDescription;
var marker = new google.maps.Marker({
map: map,
position: latlng,
title:'pk:'+name,
MAX_ZINDEX: zInd,
icon: image
});
bounds.extend(latlng);
setMarker(map, marker, name, locationDescription);
MAX_ZINDEXis a constant, not an attribute of a marker.
The relevant MarkerOption is zIndex:
var marker = new google.maps.Marker({
map: map,
position: latlng,
title:'pk:'+name,
zIndex: zInd,
icon: image
});
This sets the marker's zIndex attribute to the value you have calculated, which is one more than the API's maximum value.
Most of your code makes sense, but your definition of the MarkerOptionsapi-doc object doesn't make sense. Try changing your marker creation code to this:
var marker = new google.maps.Marker({
map: map,
position: latlng,
title:'pk:'+name,
zIndex: zInd,
icon: image
});
Since you have already set the value of zInd higher than google.maps.Marker.MAX_ZINDEX, making this change should place the marker higher in the zIndex and thus above the other markers on the map.

I'm trying to show a marker on a map with set coordinates and then show the users geolocation in relation to the marker. I'm able to show both the marker and geo location (if available) on the map but the map is only positioned on the geo location. I think I need to use fitBounds to fit both markers in view but I can't get this to work. Can anyone help?
function initialize() {
var latitude = 51.5039713;
var longitude = -0.114518;
var mapCanvas = document.getElementById('map-directions');
var center = new google.maps.LatLng(latitude, longitude);
var zoom = 18;
var mapOptions = {
center: center,
zoom: zoom,
mapTypeId: google.maps.MapTypeId.ROADMAP,
scrollwheel: false
}
var map = new google.maps.Map(mapCanvas, mapOptions)
marker = new google.maps.Marker({
map:map,
animation: google.maps.Animation.DROP,
position: center,
icon: '/pickup.png'
});
// Try HTML5 geolocation
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var bounds = new google.maps.LatLngBounds();
var pos = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var geolocation = new google.maps.Marker({position: pos, map: map, title: 'Your geolocation', });
bounds.extend(geolocation.getPosition());
map.fitBounds(bounds);
}, function() {
handleNoGeolocation(true);
});
} else {
// Browser doesn't support Geolocation
handleNoGeolocation(false);
}
}
initialize the bounds with the position of marker as argument:
var bounds = new google.maps.LatLngBounds(center);
Related to the comment:
To have both markers in viewport but 1 in center you may:
create a circle` with:
pos as `center
the distance between pos and center as radius
call map.fitBounds() by using the bounds of the circle as argument
var pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude),
circle = new google.maps.Circle({center:pos,
radius: google.maps.geometry.spherical.computeDistanceBetween(pos,center)}),
geolocation = new google.maps.Marker({position: pos, map: map, title: 'Your geolocation'});
map.fitBounds(circle.getBounds());
I have a map I am developing. The basic Google RED DROPLET icon shows up as my marker image. How can I get my own custom image to come up? I have individual images for just about all 50 of my markers (will be company's logo).
Can someone help? Here's the link.
Any help setting custom markers with the code I have presently would be great.
From actual code:
var image = './beachflag.png';
[...]
var marker=new google.maps.Marker({
position: myPosition,
map: map,
icon: image
});
Your code:
var point = new google.maps.LatLng(37.984798,-121.312094);
var marker = createMarker(point,'<div style="width:205px"><center><img src="images/sampleuopsign.jpg" /></center><h2>University of the Pacific</h2>3601 Pacific Avenue<br>Stockton, California 95211<br>209.946.2011<br><small>On the web visit: <a href="http://www.pacific.edu">www.Pacific.edu<\/a></small><\/div>');
var image = 'icons/orange_arrow.png'; // this will be gmarkers[0]
What you need to do:
var point = new google.maps.LatLng(37.984798,-121.312094);
var image = 'icons/orange_arrow.png'; // this will be gmarkers[0]
var marker = createMarker(point,'<div style="width:205px"><center><img src="images/sampleuopsign.jpg" /></center><h2>University of the Pacific</h2>3601 Pacific Avenue<br>Stockton, California 95211<br>209.946.2011<br><small>On the web visit: <a href="http://www.pacific.edu">www.Pacific.edu<\/a></small><\/div>', image);
And change CreateMarker:
function createMarker(latlng, html, img) {
// Note here the addition of the img parameter
var contentString = html;
var marker = new google.maps.Marker({
position: latlng,
map: map,
***icon: img,***
zIndex: Math.round(latlng.lat()*-100000)<<5
});
[...]
EDIT
A quick test with your code and my mods.
You can select the image and later associated that image with your lat and long, in this case there is one function that creates the marker.
if(location.category=="TEAMNAME"){
var image='img/blueMarker.png';
}
if(location.category=="TEAMNAME2"){
var image='img/redMarker.png';
}
function displayLocation(location){
var content = '<strong><p>Team: ' +location.category + '</strong>';
var latLng = new google.maps.LatLng(parseFloat(location.latitud), parseFloat(location.longitud));
var marker = new google.maps.Marker({
position: latLng,
map: map,
draggable: true,
visible: true,
title: location.category,
icon: image
});
/*Content window asociated to created markers*/
google.maps.event.addListener(marker, 'click', function(){
infowindow.setContent(content);
infowindow.open(map, marker);
});
return marker;
}
I've 2 function as below:
function addMarker() {
marker = new google.maps.Marker({
position: Gpoint,
map: map,
draggable: true,
animation: google.maps.Animation.DROP
});
map.panTo(Gpoint);
google.maps.event.addListener(marker, "rightclick",
function (point) {
showContextMarker(point.latLng); } );
$('.contextmenu').remove();
};
function delMarker() { marker.setMap(null); $('.contextmenu').remove(); };
So, as may understand I have a Context Menu having "Delete Marker" option on it.
I am binding a "rightclick" listener during adding a marker, to show this menu.
Everything is working without any problem till this moment.
But when I try to click on a marker to delete; it is effecting only the last added marker.
When I try again; nothing happens.
So my idea is to get the clicked marker's id (or something that may well be useful) and run this deleting function according to this.
Briefly; I want to delete the marker that I clicked on, from a map having multiple markers.
Do you have any approach to solve this problem ?
Thanks in advance!
SOLVED!
Here is the solution. Thank you Fatih. it was impossible without your guidance:
var id;
var markers = {};
var addMarker = function () {
marker = new google.maps.Marker({
position: Gpoint,
map: map,
draggable: true,
animation: google.maps.Animation.DROP
});
map.panTo(Gpoint);
id = marker.__gm_id
markers[id] = marker;
google.maps.event.addListener(marker, "rightclick", function (point) { id = this.__gm_id; delMarker(id) });
}
var delMarker = function (id) {
marker = markers[id];
marker.setMap(null);
}
Calling delete function by: delMarker(id)
Ps: "Right clicking is enough on this case"
Thank you!
Working Sample on jsFiddle
Google Maps doesn't manage your markers. So all your markers should be managed by yourself.
Make a global marker object and push all markers to this object. And give unique id to each marker when getting a marker instance. Then when you want to delete a marker take its id and find this marker in global marker object and finally call this marker instance's setMap method with passing null argument.
Also I've added a demo that works on jsFiddle. Code is heavily documented.
Your psuedo code should be like this. For more detailed code please look the demo.
var currentId = 0;
var uniqueId = function() {
return ++currentId;
}
var markers = {};
var createMarker = function() {
var id = uniqueId(); // get new id
var marker = new google.maps.Marker({ // create a marker and set id
id: id,
position: Gpoint,
map: map,
draggable: true,
animation: google.maps.Animation.DROP
});
markers[id] = marker; // cache created marker to markers object with id as its key
return marker;
}
var deleteMarker = function(id) {
var marker = markers[id]; // find the marker by given id
marker.setMap(null);
}
Complementing the #Fatih answer you should manage the markers. For example you could add each marker in a array and then to remove, you could find this marker into the array and set the val in the map null.
Just pass your marker in the rightclick function. For example:
var marker = new google.maps.Marker({
position: event.latLng,
map: map,
draggable: true,
title: 'Hello World!'
});
google.maps.event.addListener(marker, "rightclick", function (point) {delMarker(marker)});
And make the function look this:
var delMarker = function (markerPar) {
markerPar.setMap(null);
}
Your markers will be removeable on the rightclicks.
this worked for me:
a second currentId, if you have a better idea, let me know
var actualMarkerId = 0;
var currentId = 0;
if (actualMarkerId>0) {
deleteMarker(actualMarkerId);
console.log(actualMarkerId);
}
var id = uniqueId(); // get new id
actualMarkerId = id;
For minimal changes
var newid=0;
for (var index in results){
var marker = new google.maps.Marker({
map: map,
icon: image,
__gm_id: = newid+1,
});
}
Now marker['__gm_id'] still has a value
Simple,Use Global array for marker Objects.
Push marker object in that array on plotting marker.
Yes,We can use Id in Marker Object for Unique Reference.
Code As Below
MarkerArray = []
marker = new google.maps.Marker({
Id: 1,
position: new google.maps.LatLng(Lat,Long),
type: 'info'
});
MarkerArray.push(marker);
To remove particular Marker,Find that Element Index using Unique Id for Each Marker.
var MarkerIndex = MarkerArray.findIndex(function GetIndex(element) {
return element.Id == 1;
});
MarkerArray[MarkerIndex].setMap(null);
MarkerArray.splice(MarkerIndex, 1); // to remove element from global array
I am using google map API V3. i want to use a custom marker instead of that red marker. Earlier the code was
var myOptions = {
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
// display map
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
if(display_marker) {
// create a map marker
var marker = new google.maps.Marker({
map: map,
position: latlng
});
}
but for the custom marker, i changed the code to
var myOptions = {
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
// display map
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
// create a map marker
var image = 'imgs/pin.png';
var marker = new google.maps.Marker({
map: map,
position: latlng,
icon: image
});
but yet this is not working.
The image path is likely incorrect but,
You could also eliminate var image and just define the icon under var marker depending on your situation.
var marker = new google.maps.Marker({
map: map,
position: latlng,
icon: 'imgs/pin.png',
});
Your code looks okay.
Perhaps the image path is off.
Try putting the pin.png in the same folder as the map and then changing the
var image = 'imgs/pin.png';
to
var image = 'pin.png';
If it works, then you need to revise the path, probably to something like
var image = '/imgs/pin.png';
or
var image = '../imgs/pin.png';
I am doing a google map which will read a set of coordinates and put the marker on the map one by one.
Below is my idea:
function A{
for loop(
set marker
call setTimeout('A',2seconds)
)
}
my idea is to set a marker and use setTimeout to wait 2 seconds and then set the next marker.
However, it doesn't work. it show all the markers at the same time and repeat to renew all markers.
How can i achieve my goal?
Thanks for your help!!!!!!!!!!!!!!!
Here is my code:
function marker(){
var marker;
var i=0;
while(i<locations.length){
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
animation: google.maps.Animation.DROP,
map: map
});
i=i+1;
var t=setTimeout("marker()",2000);
}
}
marker();
You need to return after setting the first marker. You also need a parameter to A which specifies which marker to show.
function marker(i){
if (i > locations.length) return;
var marker;
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
animation: google.maps.Animation.DROP,
map: map
});
var t=setTimeout("marker("+(i+1)+")",2000);
}
marker(0);
