I am currently creating a website for a school project. I have created a code that should display a map with some markers and some lines that represent borders between countries. The problem is that when I load this map I can display the lines but the markers all disappeared. Any help would be very appreciated. I alredy own a valid key.

I'm new at programming and trying to create geo web app using gmaps.js. Currently I'm stuck at address searching.
Here the code in script.js file:
Creating map:
function initialize()
{
var mapProp = {
center:new google.maps.LatLng(51.508742,-0.120850),
zoom:5,
mapTypeId:google.maps.MapTypeId.ROADMAP
};
var map=new google.maps.Map(document.getElementById("googleMap")
,mapProp);
}
google.maps.event.addDomListener(window, 'load', initialize);
Creating search:
GMaps.geocode({
address: $('#adress').val(),
callback: function(results, status) {
if (status == 'OK') {
var latlng = results[0].geometry.location;
map.setCenter(latlng.lat(), latlng.lng());
map.addMarker({
lat: latlng.lat(),
lng: latlng.lng()
});
}
}
});
and HTML:

What i'm doing wrong?
You are Calling '#address' instead of '#adress' as your HTML tags are
<input type="text" id="adress" name="adress">
Its a Typo Mistake , Correct it and Get Back :)
I have an external json which I am trying to overlay on a google map. The overall plumbing works fine.
The map gets generated. Data gets iterated, and markers are placed by reading the coordinates. But the when i look at the map the coordinates are way off on the map. The data set can not be wrong, i can give my word on that. Is there some adjustment I need to make to get this thing map to each other. Here is my code
<!DOCTYPE html>

};
map = new google.maps.Map(document.getElementById("map_canvas"),
mapOptions);
}

$(document).ready(function() {

So I am preparing a page which has a Google Map and there are two forms namely latitude and longitude , and a submit button.
On entering the longitude and latitude the map is centered to the desired location and puts a marker there.
The problem I am facing is that whenever I put a new lat/long , the old marker won't go.
So basically if entered first lat/long : 10/12 , it would center to that and place a marker there, but when i enter the second lat/long (say) : 11/12 , it would center to that too and place a marker there also while the first one is not removed.
I want the page to be whenever the a new entered in the form only that one reflects in the form no old markers.
Here's my CODE :
<!DOCTYPE html>
<html>
<head>

<meta charset="utf-8">

};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
function pan() {
var panPoint = new google.maps.LatLng(document.getElementById("lat").value, document.getElementById("lng").value);
map.setCenter(panPoint)
var marker = new google.maps.Marker({
map: map,
position: panPoint,

Longitude:<input type="text" id="lng">
<input type="button" value="updateCenter" onclick="pan()" />
<div id="map-canvas"></div>
</body>
</html>
Some help would be useful
You need to clear markers each time in order to do that.
To clean marker keep marker as global variable, eg.
function pan() {
try{
marker.setMap(null);//clear marker
}
catch(err){
}
var panPoint = new google.maps.LatLng(document.getElementById("lat").value, document.getElementById("lng").value);
map.setCenter(panPoint)
//declare marker as global variable
marker = new google.maps.Marker({
map: map,
position: panPoint,
});
}
That should do the trick.
use this code
<!DOCTYPE html>
<html>
<head>
<title>Google Maps</title>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">

var map;

};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
function pan() {
deleteOverlays();
var panPoint = new google.maps.LatLng(document.getElementById("lat").value, document.getElementById("lng").value);
map.setCenter(panPoint)
var marker = new google.maps.Marker({
map: map,
position: panPoint,
});
markersArray.push(marker);
}
function deleteOverlays() {
if (markersArray) {
for (i in markersArray) {
markersArray[i].setMap(null);
}
markersArray.length = 0;
}
}
</script>

Longitude:<input type="text" id="lng">
<input type="button" value="updateCenter" onclick="pan()" />
<div id="map-canvas"></div>
</body>
</html>
In the pan function before adding the new marker, try to remove all the present markers Google Maps API v3: How to remove all markers?
I am just getting started with the Maps API and I was trying to copy the following example.
https://code.google.com/apis/maps/documentation/javascript/examples/streetview-simple.html
When I copy the source I get the following error in the script.
google is not defined
Line 11
var fenway = new google.maps.LatLng(42.345573,-71.098326);
This is the html file I am using.

The google example loads perfectly but my code does not.
I have seen a few people getting this error but none of the fixes listed seem to work for me. Have I just made a basic error while copying the script?
There is the protocol missing in the path.
//maps.googleapis.com/maps/api/js?sensor=false
should be
http://maps.googleapis.com/maps/api/js?sensor=false
(it's missing in many of the examples)
I am using Google Maps for my website and I wander how can I use the Markers as links? I mean when I click a marker to open a particular link.
Thank you in advance!
That's actually very easy to do. Simply attach an event handler to your marker, and then launch the link by setting window.location.href to your URL. Check out the following examples, which I think should be self explanatory:
Using the v3 API:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<title>Google Maps Marker as a Link</title>
<script src="http://maps.google.com/maps/api/js?sensor=false"
type="text/javascript"></script>
</head>
<body>
<div id="map" style="width: 500px; height: 400px;"></div>
<script type="text/javascript">
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 2,
center: new google.maps.LatLng(35.55, -25.75),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var marker = new google.maps.Marker({
position: map.getCenter(),
url: 'http://www.google.com/',
map: map
});
google.maps.event.addListener(marker, 'click', function() {
window.location.href = marker.url;
});
</script>
</body>
</html>
Using the V2 API:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>
<title>Google Maps Marker as a Link</title>
<script src="http://maps.google.com/maps?file=api&v=2&sensor=false"
type="text/javascript"></script>
</head>
<body onunload="GUnload()">
<div id="map" style="width: 500px; height: 400px;"></div>
<script type="text/javascript">
var map = new GMap2(document.getElementById("map"));
var centerPoint = new GLatLng(35.55, -25.75);
map.setCenter(centerPoint, 2);
var marker = new GMarker(map.getCenter());
marker.url = 'http://www.google.com/';
map.addOverlay(marker);
GEvent.addListener(marker, 'click', function() {
window.location.href = marker.url;
});
</script>
</body>
</html>
The above examples will add a marker somewhere in the atlantic ocean. When you click on it, you'll be forwarded to a popular search engine.
To get this to open in a new tab add the following right after the "window.location.href = marker.url;":
window.open(this.url, '_blank');
So you would have:
google.maps.event.addListener(marker, 'click', function() {
window.location.href = marker.url;
window.open(this.url, '_blank');
});
