I am totally lost, my marker won't show on the map. I did the exactly as shown on the Google Maps example. I can't get the marker to appear on mylatlng. The icon image is in the same folder as the html page.
$("#b1").on("click",function(){
function initialize(){
var myLatLng = new google.maps.LatLng(40.7404, -74.1789);
var mapOptions = {
zoom:5,
center: myLatLng
}
var map=new google.maps.Map(document.getElementById("googleMap"),mapOptions);
var image = 'marker.png';
var myLatLng = new google.maps.LatLng(40.64043,-74.2789);
var Name = new google.maps.Marker({
position: myLatlng,
map: map,
icon: image
});
marker.setMap(map);
});
google.maps.event.addDomListener(window, 'load', initialise);
UPDATE:
FIGURED IT OUT. I need to have google.maps.event.addDomListener(window, 'load', initialise); outside the function.
UPDATE 2:
well i don't need to have the 'initialize' within google.maps.event.addDomListener(window, 'load', initialise); if i do that. it would create only one marker. After deleting the it, marker is working for all the 30 onClick list that i have. And yeah i don't need the function initialize()
Couple of mistakes here ,
1:You were using wrong marker variable to set Map,initialize marker as global variable.
2:To get map display you have to use Google map Dom Events google.maps.event.addDomListener(document.getElementById('yourbuttonid'), 'click', initialize);
3:And it will be out of the intialise function.

I've included a google map on my webpage with a marker at the location. What I want to add is an existing infoWindow of that location when the page loads.
This is the code i have:
<script>
function initialize() {
var mapCanvas = document.getElementById('map-canvas');
var mapOptions = {
center: new google.maps.LatLng(51.257195, 3.716563),
zoom: 10,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(mapCanvas, mapOptions);
new google.maps.Marker({
position: new google.maps.LatLng(51.257195, 3.716563),
map: map
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>

Now the "AXA..." is an existing point of interest on google maps, how would i go about that my marker is actually 'linked' to that existing point of interest with the infowindow opened by default.
in short: i would like a marker on that location with the infowindow opened when the webpage loads.
I think the solution would be to first find the place_id and then add your marker using the place ID you found rather than using longitude and latitude.
I created a live demo here:
https://jsfiddle.net/qzo41qzd/
There is also an example in the documentation about placing a marker on the google map using place_id:
https://developers.google.com/maps/documentation/javascript/places#placeid
So Im working on my project and the user is to enter an address after its been created in the database, i want it to show in a google map. I've found out the coordinates for the map through this link :
http://www.codeproject.com/Tips/650139/Finding-Co-ordinates-of-an-Address-in-ASP-NET-Csha
However this link shows the coordinates as a label where as i have a java script method as follows :
<script type="text/javascript">
var myCenter = new google.maps.LatLng(1.303895, 103.831941);
function initialize() {
var mapProp = {
center: myCenter,
zoom: 18,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
var marker = new google.maps.Marker({
position: myCenter,
});
marker.setMap(map);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
The script works fine if i enter the coordinates myself. I've tried parsing the latitude and longitude through a label and using document.getElementById() method however the map does not show.
Any clue how i can solve this ?
i was checking out the google map api to integrate in my website.
made this page with what ever i could understand so far.
everything is working fine but there is just one thing, that i want three markers on the same map.
when i am adding more than one markers then the map stops working.
test link : http://goo.gl/X9q92s
you will have a better understanding if u see my link.
this is the code that i got from google map api.
and i edited it to get grey scale map with my desired marker box.
i just want to add two more....
Please help.
<script>
function initialize() {
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
zoom: 4,
center: myLatlng
}
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Hello World!'
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
You should place your "new marker" code into its own function, like so:
function LoadMarkers(name, lat, lng) {
var MarkerLatLng = new google.maps.LatLng(lat, lng);
var MarkerOption = { map: map, position: MarkerLatLng, title: name};
var Marker = new google.maps.Marker(MarkerOption);
}
Putting this into its own function allows you to "refresh" the markers with ease, by simply invoking the function with a timer or some other event. A program I'm working on refreshes the map every few seconds, as my data source is constantly changing with new/removed/updated records that should be reflected immediately on the map. I think this is a great way to do this.
Then, in your program, you can create a loop that shoots the information for each marker in by invoking the LoadMarkers function. I've recently fallen in love with SqlDataReader.
Your loop would iterate through a SqlDataReader and each record read will invoke the script like so:
InvokeScript("LoadMarkers", New Object() {name, lat, lng})
This is a great moment to also add an InfoWindow for each marker.
var infowindow = new google.maps.InfoWindow(
{
content: "Content here"
});
As well as a click listener for the InfoWindows. ;)
google.maps.event.addListener(Marker, 'click', function () {
typeof infoWindowsOpenCurrently !== 'undefined' && infoWindowsOpenCurrently.close(); //If there is an InfoWindow currently open, close it
infowindow.open(map, Marker); //Open a new one for the selected marker
infoWindowsOpenCurrently = infowindow; //Set the new info window to the temporary variable
});
Some might not like this method of using a loop. I like it because I can "personalize" each marker for each record, while personalizing each of their InfoWindows too. In my code above, assume that "name" is a unique ID that lets you specify a specific marker for later use, such as identifying which marker was clicked and which InfoWindow is currently open.
I'm trying to create my own map using google map.
I want to create a list showing all existing markers on the map. When user clicks on one button/link from the list, the corresponding marker will be centered and its infoWindow will be displayed, i.e. the same effects as the user clicks on the marker.
I have tried a number of solutions, but I could get none of them working. Can anyone please offer me a simple solution for this? Thanks in advance!
My existing code is as follows,
google.maps.event.addDomListener(window, 'load', function() {
var map = new google.maps.Map(document.getElementById('map'), {
center: new google.maps.LatLng(19.642588,151.171875),
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl: false
});
var infoWindow = new google.maps.InfoWindow;
var onMarkerClick1 = function() {
var marker = this;
infoWindow.setContent('content of infowindow');
infoWindow.open(map, marker);
};
var marker1 = new google.maps.Marker({
map: map,
position: new google.maps.LatLng(19.642588,151.171875),
});
google.maps.event.addListener(marker1, 'click', onMarkerClick1);
this won't center the map on it, but will move so the whole balloon is visible
http://econym.org.uk/gmap/example_map2.htm
as simple as i can get it. yes, please use GMarker etc.
don't forget this in the header <script src="http://maps.google.com/maps?...
you'll need html that includes
<div id="map" style="width: 550px; height: 450px"></div>
<div id="side_bar">Marker One<br /></div>
and then javascript
var map = new GMap2(document.getElementById("map"));
map.setCenter(new GLatLng(19.642588, 151.171875), 8);
var point = new GLatLng(19.642588, 151.171875);
var marker = new GMarker(point);
GEvent.addListener(marker, "click", function () {
marker.openInfoWindowHtml("this marker has been clicked");
});
function myclick(i) {
GEvent.trigger(marker, "click");
}
map.addOverlay(marker);
I want to draw a custom rectangle which is resizable and draggable with a close button and
which is formed with the bounds returned by the query in the database.
Thanks
This is a rectangle resizable and dragabble. A little search and some trying would give you what you need.
function initialize() {
var myOptions = {
center: new google.maps.LatLng(44.5452, -78.5389),
zoom: 9,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map_canvas'),
myOptions);
var bounds = new google.maps.LatLngBounds(
new google.maps.LatLng(44.490, -78.649),
new google.maps.LatLng(44.599, -78.443)
);
var rectangle = new google.maps.Rectangle({
bounds: bounds,
editable: true
});
rectangle.setMap(map);
}
google.maps.event.addDomListener(window, 'load', initialize);
Hope this helps!
I think the only thing you need to add is "draggable: true" in rectangle options.
So, it should be something like this;
var rectangle = new google.maps.Rectangle({
bounds: bounds,
editable: true,
draggable: true
});
This will make the rectangle resizable and draggable. Also in the body of the page create one button.
<body >
<button onclick="remove()">Close</button>
</body>
Inside remove function you can write your code to connect to database. You will have to declare the bounds outside initialize() to access it. This link might help you to understand how to connect google maps and MySQL. https://developers.google.com/maps/articles/phpsqlajax_v3
