I want to pass related marker id by clicking marker on google map. I am using marker.getId() function to retrieve marker id. But the marker id is not passing along with url. How can i do this? Any Help?
function AddressMap(lat,lang,markerid)
{
var latLng = new google.maps.LatLng(lat,lang);
var marker = new google.maps.Marker({
'map': map,
position: latLng,
'latitude' :lat,
'longitude' :lang,
icon: image,
shadow: shadow,
id: markerid
});
markers.push(marker);
google.maps.event.addListener(marker, 'click', function() {
window.location = "www.cickstart.com/" + marker.getId();
});
}
you can try directly to access the id:
google.maps.event.addListener(marker, 'click', function() {
window.location = "www.cickstart.com/" + marker.id;
});
the best way to do this is add a metadata to marker
var marker = new google.maps.Marker(markerOptions);
marker.metadata = {type: "point", id: 1};
if you have so many marker push the marker to array marker.
You can add any data that you want. and simply call it, set it or get it.
the sample like this one:
markers[0].metadata.id

I am trying to activate the infowindow for a custom marer, yielding a small description about the marker, I'm having some trouble at the moment, I have the custom marker working but I can't get the infowindow to show.
I tried calling the listener for the marker and storing it in a variable "customMarker", then calling another mouseover listener to activate the infowindow, but I'm having no luck, can anyone help me out?
var map;
//Creates a custom icon to be placed on the map
var goldStar = 'https://cdn2.iconfinder.com/data/icons/august/PNG/Star%20Gold.png';
function initialize() {
//Sets the zoom amount for the map, the higher the number, the closer the zoom amount
var mapOptions = {
zoom: 18
//center : myLatLng
};
//The map object itself
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
var contentString = 'This is a custom toolTip';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
// Tries to find user location using HTML 5
if(navigator.geolocation)
{
//sets the map to the position of the user using location
navigator.geolocation.getCurrentPosition(function(position) {
var pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
map.setCenter(pos);
}, function() {
handleNoGeolocation(true);
});
} else {
// Browser doesn't support Geolocation
handleNoGeolocation(false);
}
var customMarker = google.maps.event.addListener(map, 'click', function(event) {
placeMarker(event.latLng, map);
});
//This listener is not working
//google.maps.event.addListener(customMarker, 'mouseover', function() {
//infowindow.open(map,customMarker);
//});
}
function placeMarker(location, map)
{
var marker = new google.maps.Marker({
position: location,
icon: goldStar,
map: map,
title: "custom marker",
draggable:true
});
map.panTo(location);
}
The google.maps.event.addListener function does not return a marker. This won't work:
var customMarker = google.maps.event.addListener(map, 'click', function(event) {
placeMarker(event.latLng, map);
});
Assign the event listener in your placeMarker function to the marker you create (also gives the advantage of maintaining function closure on the marker):
function placeMarker(location, map) {
var marker = new google.maps.Marker({
position: location,
icon: goldStar,
map: map,
title: "custom marker",
draggable: true
});
var contentString = 'This is a custom toolTip';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
google.maps.event.addListener(marker, 'mouseover', function() {
infowindow.open(map,marker);
});
map.panTo(location);
}
working fiddle
in the following code generated an undetermined number of markers, this works well.
for(i=0;i<idr.length;i++){
var LatLng = new google.maps.LatLng(lat[i], lng[i]);
m[i] = new google.maps.Marker({
position: LatLng,
icon: image,
map: map,
draggable: false,
val: idr[i]
});
}
I want to get the properties of the corresponding marker when the mouse passes over this
This does not apply for you should create a function for each marker and can not be that many
This function only access the first marker
google.maps.event.addListener(m[0], "click", function(e) {
var latitud = e.latLng.lat();
alert(latitud);
});
use this inside the callback to get access to the current marker(m[i] will not work there, because it will always refer to the last created marker)
google.maps.event.addListener(m[i], 'mouseover', function() {
alert(this.val)
});
for(i=0;i<idr.length;i++){
var LatLng = new google.maps.LatLng(lat[i], lng[i]);
m[i] = new google.maps.Marker({
position: LatLng,
icon: image,
map: map,
draggable: false,
val: idr[i]
});
google.maps.event.addListener(m[i], 'mouseover', function() {
//Do stuff
});
}
The above is how I would do it.
I have created a function to add the marker when there is no marker on map or remove the original marker and added a new one to replace it. However, i can add the first part of script successfully to add the marker on map. however, the original marker can not be removed and new marker could not added when i click the map again. Can anyone suggest what is the problem?
/*Create a listener to record the Click event of the google map and define it as the starting point (i.e. Origin in Google Direction
service*/
google.maps.event.addListener(map, 'click', function(event) {
if (origin == null) {
origin = event.latLng;
lat = origin.lat();
lng = origin.lng();
UpdateLatLng();
var startimage = 'images/Start4.png';
StartMarker = new google.maps.Marker({
map: map,
position: origin,
icon: startimage
});
} else {
//Relocate the Starting point and assign the new position to Textbox
alert ("The starting point was relocated on screen");
StartMarker.setMap(null);
directionsDisplay.setMap(null);
directionsDisplay.setPanel(null);
directionsDisplay.setDirections({routes: []});
var origin = event.latLng;
lat = origin.lat();
lng = origin.lng();
UpdateLatLng();
var startimage = 'images/Start4.png';
StartMarker = new google.maps.Marker({
map: map,
position: origin,
icon: startimage
});
}
});
This works for me:
var StartMarker = null;
/*Create a listener to record the Click event of the google map and define it as the starting point (i.e. Origin in Google Direction
service*/
google.maps.event.addListener(map, 'click', function(event) {
if (!StartMarker) {
origin = event.latLng;
lat = origin.lat();
lng = origin.lng();
StartMarker = new google.maps.Marker({
map: map,
position: origin
});
} else {
//Relocate the Starting point and assign the new position to Textbox
alert ("The starting point was relocated on screen");
StartMarker.setMap(null);
var origin = event.latLng;
lat = origin.lat();
lng = origin.lng();
StartMarker = new google.maps.Marker({
map: map,
position: origin
});
}
});
working example
Try to use the existing Marker like:
// Will change the poisition
StartMarker.setPosition(origin);
// Will change the Icon
StartMarker.setIcon(startimage);
I have created a google map using V3 js API, and inside the map I am showing multiple markers. When I am clicking on a markers it does an ajax call and shows the result in the infowindow. I have added an external link outside the map, clicking on which it will display the corresponding marker result in side the map. I have used the below code to do the functionality..
$('#marker_link').click(function () {
var longitude = $(this).find("#longitude").val();
var latitude = $(this).find("#latitude").val();
var index = $(this).find("#index").val();
google.maps.event.trigger(gmarkers[index], "click", {
latLng: new google.maps.LatLng(latitude, longitude)
});
});
This code is pulling the marker data correctly and showing in a window. But at that time the map goes blank. How can we fix it. How can we keep the map along with the store result.
Here gmarkers[ ] is a global array where I am keeping all the markers that are created during the map is rendered.
The below code I have used while showing markers in the map for the first time.
var marker = new google.maps.Marker({
map: map,
position: new google.maps.LatLng(pLat, pLong),
});
gmarkers.push(marker);
google.maps.event.addListener(marker, 'click', function (event) {
var dataString = 'store_id=' + {{ store.store_id }}
$.ajax({
type: "GET",
url: GET_STORE_DATA,
data: dataString,
success: function(res) {
if(res != '') {
var contentString = res;
var infoWindow = new google.maps.InfoWindow({ content: contentString });
infoWindow.setPosition(event.latLng);
infoWindow.open(map);
google.maps.event.addListener(map, 'click', function() {
infoWindow.close();
});
} else {
alert('No data found')
}
}
});
});
My Code looks like this:
var map = /*some google map - defined earlier in the code*/;
var geocoder = new google.maps.Geocoder();
var address = 'Some Address, Some Street, Some Place';
geocoder.geocode({'address':address},function(results,status){
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var infobox = new google.maps.InfoWindow({
content: 'Hello world'
});
for(i in results){
var marker = new google.maps.Marker({
map: map,
position: results[i].geometry.location
});
google.maps.event.addListener(marker, 'click', function() {
infobox.setContent('blablabla');
infobox.open(map,marker);
alert(infobox.content); //displays 'blablabla'
});
}
}
});
Basically it's creating some markers on a single map based on a given address-string. It adds an infoWindow to the markers that opens on click.
Problem is: the infoWindow displays empty.
Screenshot here:
PS: Using Maps API V3
I just ran into the same problem, and found the very simple cause of it: The text in the info window was actually displayed, but in white color, and therefore just not visible on the white background. Giving the content a different color via CSS solved the problem for me.
Basically you need to use a function external to your marker adding-loop to add the infobox message to each marker... for an example and detailed explanation see:
http://code.google.com/apis/maps/documentation/javascript/events.html#EventClosures
Here is how I have done it.
var map,markersArray,infowindow; //infowindow has been declared as a global variable.
function initialize(){
var myOptions = {
zoom: 14,
center: new google.maps.LatLng(51.5001524,-0.1262362),
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
infowindow = new google.maps.InfoWindow(
{
size: new google.maps.Size(150,50)
});
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
markersArray = [];
}
function createMarker(latlng, html,zoom) {
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);
});
marker.MyZoom = zoom;
return marker;
}
You can find the working example here and the complete javascript here.
I have resolved issue by adding below code.
setTimeout(function () { GeocodeMarker.info.open(GoogleMap,
GeocodeMarker); }, 300);
Thanks
