Im building a site for a friend of mine and im having a hell of time trying to get the map marker to show up, I gotta admit im not much for java coding but Ive done my share of it. Im a designer and 3d motion graphics artist.
Im currently working on this template in Dreamweaver CC and I chose it cause thats how Ive been constructing sites for years.
So he gave me a template that he wanted me to use 427_timeline (its A freebie).
The modified version of this template can be seen here http://johnnybobs3ddesignz.com/
My first time but works the same pretty much. Heres My code, if someone could help me Id appreciate that so much, it would be mighty groovy dude ;)
<script>
function initialize()
{
var mapOptions = {
center: new google.maps.LatLng(34.073809, -118.323371),
zoom: 15,
scrollwheel: false,
mapTypeId:google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("templatemo-map")
,mapOptions);
var location = new google.maps.LatLng(34.073809, -118.323371);
var contentString = '<h2>Runyon Investment & Realty</p>';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
var marker = new google.maps.Marker({
position: mylatLng,
title: 'Runyon Investment & Realty',
visible: true
});
marker.setMap(map);
}
google.maps.event.addDomListener(window, 'load', initialize);
google.maps.event.addDomListener(window, 'resize', function()
{
map.setCenter(center);
});
</script>
I get two javascript errors with your code as is:
Uncaught ReferenceError: mylatLng is not defined
Uncaught ReferenceError: map is not defined
Because mylatLng is not defined in your code (you define location) and map is local to your initialize function
Working code snippet:
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(34.073809, -118.323371),
zoom: 15,
scrollwheel: false,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("templatemo-map"), mapOptions);
var location = new google.maps.LatLng(34.073809, -118.323371);
var contentString = '<h2>Runyon Investment & Realty</p>';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
var marker = new google.maps.Marker({
position: location,
title: 'Runyon Investment & Realty',
visible: true
});
marker.setMap(map);
google.maps.event.addDomListener(window, 'resize', function() {
map.setCenter(center);
});
}
google.maps.event.addDomListener(window, 'load', initialize);

Just use this link
https://developers.google.com/maps/documentation/javascript/
to get desired informations.
for example use the following snippet.
They use the
map - option
in the init of the marker. Just try that in your code too.

First I checked without setTimeout function google map API is fully loaded or not using map idle function. it's working fine. but I tried using the setTimeout function in the google map loading page. the map is loaded successfully. but map idle function is not working on how to fix this issue.

How to achieve this scenario.
You can use the tilesloaded event of the Maps Javascript API Events. The tilesloaded is used to detect when the map has been fully loaded. A sample POC below using your current implementation.
var map;
function initMap() {
var myLatLng = {lat: -25.363, lng: 131.044};
map = new google.maps.Map(document.getElementById('map'), {
zoom: 4,
center: myLatLng
});
map.addListener('tilesloaded', function() {
console.log('map is loaded');
});
google.maps.event.addListenerOnce(map, 'idle', function(){
console.log('map is idle')
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: 'Hello World!'
});
});
}
If this doesn't help you, you can also check the answer from this Stackoverflow question How can I check whether Google Maps is fully loaded?. It appears a lot of users were also experiencing this issue before.
Hope this information find you helpful and good luck on your applicaion!
Use titesloaded event to listen to complete map load.
New to coding so apologies in advance... am looking to add custom icon markers (multiple) to my map, but having trouble displaying even one (the map itself shows fine though).
What's wrong with my code as it stands? (below):

<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />

<script src="http://maps.googleapis.com/maps/api/js?key=TEST (I have a valid key here)"
type="text/javascript"></script>
</head>
<body>
<div id="map" style="width: 700px; height: 500px;"></div>
<script type="text/javascript">
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 11,
center: new google.maps.LatLng(53.480782, -2.2445527),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var image = 'https://developers.google.com/maps/documentation/javascript/examples/full/images/beachflag.png';
var marker = new google.maps.Marker({
position: {lat: 53.480782, lng: -2.2445527},
title:"TEST",
map: map,
icon: image
});
marker.setMap(map);
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</body>
</html>
You don't have an initialize function, so your code executes before the DOM is rendered. Look at the javascript console, you will see an error Uncaught TypeError: Cannot read property 'offsetWidth' of null, if you search SO for that you will find that is due to the <div id="map"></div> not being rendered when the map code runs (related question: Google MAP API Uncaught TypeError: Cannot read property 'offsetWidth' of null).

I have been using the Google Developers Tutorial on how to add a map to my website:
https://developers.google.com/maps/tutorials/fundamentals/adding-a-google-map#the_finished_code
I cannot seem to find a way to add a pin to the map, I have used the "centre" function so that the map is centred on the lat and long of the pin, but the pin itself is not visible.
Any way to create a pin at that lat and long?
Just need to instantiate a marker Object and place it at the coordinates:
<!DOCTYPE html>
<html>
<head>
<style>
#map {
width: 500px;
height: 400px;
}
</style>
<script src="https://maps.googleapis.com/maps/api/js"></script>
<script>
function initialize() {
var mapCanvas = document.getElementById('map');
var myLatLng = {lat: 44.5403, lng: -78.5463};
var mapOptions = {
center: new google.maps.LatLng(myLatLng),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(mapCanvas, mapOptions)
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: 'Hello World!'
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map"></div>
</body>
</html>
Fiddle
Try the following:
replace center with location
before:
center: new google.maps.LatLng(myLatLng),
after:
location: new google.maps.LatLng(myLatLng),
That should do the trick (should add the Pin automatically).
The title says the question. Now, is it good to use a counter that starts from zero and when it is 1 or more I wouldn't add a marker. Or should I try to make it such that when someone clicks on the map the old marker disappears and the new one is assigned? The following code is what I have so far.. Thanks for any kind of help.
Also, how can I access the longitude and latitude in the next page?
And about capturing the map into a blob, is it a different topic or it is also related?
Thanks

I would say its up to you and your application later how you handle the markers.
You can implement a counter, create a dragable marker, depends how the app will work later on.
How will your next page look like?
One simple way could be something like this:
I use addListenerOnce to call the placeMarker function only one time and during this i write the latitude and longitude in a form field.
now you can add action parameters plus a submit button and you can access the values on your next page.
Thats the fiddle + code:
http://jsfiddle.net/iambnz/LcKy2/
function initialize() {
var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(-25.363882,131.044922),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
google.maps.event.addListenerOnce(map, 'click', function(e) {
placeMarker(e.latLng, map);
// alert(e.latLng.toString());
document.getElementById("latitude").value = e.latLng.lat();
document.getElementById("longitude").value = e.latLng.lng();
});
}
function placeMarker(position, map) {
var marker = new google.maps.Marker({
position: position,
map: map
});
map.panTo(position);
}
google.maps.event.addDomListener(window, 'load', initialize);
I am trying to get a marker to show on the google map for a website I am doing. Without the marker code the map loads fine and shows the correct location (with no marker), when I add the marker code the map no longer loads. Clearly I am missing something simple but I am not too familiar with Jquery.

Thanks for any assistance.
The map-property is expected to be a google.maps.Map-instance and the position-property has to be a google.maps.LatLng:
Furthermore you must create the marker when the map already has been created and in a scope where the maps-instance is accessible, e.g. at the end of initialize().
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(53.154662, -1.208357),
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
var marker = new google.maps.Marker({
position:new google.maps.LatLng(53.154662, -1.208357),
map: map,
title:"Hello World!"
});
}
