Error with Script

I am getting an Add Marker is undefined when using this script but I can't seem to figure out the issue. Any suggestions to remedy this error is greatly appreciated:
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<div id="map" style="width: 700px; height: 400px"></div>
<script type="text/javascript">
var latlng = new google.maps.LatLng(40.756, -73.986);
var options = {
center : latlng,
zoom : 1,
mapTypeId : google.maps.MapTypeId.ROADMAP
};
// Creating the map
var map = new google.maps.Map(document.getElementById('map'), options);
var geocoder = new google.maps.Geocoder();
var marker= new google.maps.Marker(null);
function AddMarker(address)
{
geocoder.geocode( {'address' : address}, function(results, status)
{
if (status == google.maps.GeocoderStatus.OK)
{
//map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker( {map : map,position : results[0].geometry.location });
var infowindow;
if (!infowindow)
{
infowindow = new google.maps.InfoWindow();
}
infowindow.setContent(address);
google.maps.event.addListener(marker, 'click', function()
{
infowindow.open(map,marker);
});
}
});
}
</script>

It looks like you have called the function "Add Marker" and not "AddMarker(target)"
you call infowindow just right the declaration of it.

It might be that you call AddMarker too early.

Jquery not loading the map in Wordpress

I'm using the jquery to load the Google Maps. The map doesn't load the right location until I refresh the page many times.
Here's the script:
var geocoder;
var map;
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 13,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map"), myOptions);
}
function codeAddress(address) {
geocoder.geocode({
'address': address
}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new MarkerWithLabel({
position: results[0].geometry.location,
map: map,
labelContent: address,
labelAnchor: new google.maps.Point(22, 0),
labelClass: "labels", // the CSS class for the label
labelStyle: {
opacity: 1.0
}
});
} else {
//alert("Geocode was not successful for the following reason: " + status);
}
});
}
initialize();
Any idea what I'm missing here? Thanks for any and all suggestions!

Geocoding Google Maps in Wordpress not working

I want to use the title of a Wordpress post (a location) to become a visible marker on a Google map. This code from Google works fine to show a map (without marker):
<script>function initialize() {
var mapCanvas = document.getElementById('map-canvas');
var mapOptions = {
center: new google.maps.LatLng(44.5403, -78.5463),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(mapCanvas, mapOptions)
}
google.maps.event.addDomListener(window, 'load', initialize);</script>
However, when I try to implement the geocoding part the map doesn't show. The two solutions I've tried:
Solution 1
<script type="text/javascript">// <![CDATA[
var mapOptions = {
zoom: 16,
center: new google.maps.LatLng(54.00, -3.00),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var geocoder = new google.maps.Geocoder();
var address = '3410 Taft Blvd Wichita Falls, TX 76308';
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
// ]]></script>

Solution 2:
var geocoder;
var map;
var address = "San Diego, CA";
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);

};
map = new google.maps.Map(document.getElementById("map-canvas"), myOptions);
if (geocoder) {
geocoder.geocode({
'address': address
}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (status != google.maps.GeocoderStatus.ZERO_RESULTS) {
map.setCenter(results[0].geometry.location);
var infowindow = new google.maps.InfoWindow({

size: new google.maps.Size(150, 50)
});

infowindow.open(map, marker);
});
} else {
alert("No results found");

} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
}
google.maps.event.addDomListener(window, 'load', initialize);
2014, December 4, Using Address Instead Of Longitude And Latitude With Google Maps API
What am I doing wrong or not seeing?
EDIT: changes map to map-canvas in getElementByID, but still doesn't work.
EDIT 2: through an iframe it works (but you can't move in the map, only scroll)
<iframe width="195" height="195" frameborder="0" scrolling="yes" marginheight="0" marginwidth="0" src="https://maps.google.ca/maps?center=<?php the_title('Groningen'); ?>&q=<?php the_title('Groningen'); ?>&size=195x195&output=embed&iwloc=near"></iframe>enter code here

html:
<script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript"></script>
<input type="text" id="mapaddress" />
<input type="submit" id="change" onclick="changeMap()">
<div id="map" style="width: 413px; height: 300px;"></div>

javascript google api: combining geocode with coordinates

how do I combine geocoding with known coordinates? Lets say, I want to show markers from an array of coordinates.
function codeAddress()
{
var latlng = new google.maps.LatLng(42.745334, 12.738430);
var address = document.getElementById("location").value;
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var mapOptions = {
zoom: 11,
center: results[0].geometry.location,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location,
icon: image_icon
});
}
});
}
So I have latlng coordinates and address of a value, how do I combine these two into the maps?
Thank you!

function codeAddress()
{
// The following sets up your array. Most likely you will retrieve the data
// from elsewhere, so this is just meant as an illustration.
var coords = [];
coords.push({lat:100,long:200, caption:'yo'});
coords.push({lat:150,long:250, caption:'yo yo'});
coords.push({lat:200,long:250, caption:'yo ho ho'});
var address = document.getElementById("location").value;
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var mapOptions = {
zoom: 11,
center: results[0].geometry.location,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location,
icon: image_icon
});
var myLatlng;
// loop through all the elements in the array, and add markers for each to the map object you've already created.
for (i=0;i<coords.length;i++){
myLatlng = new google.maps.LatLng(coords[i].lat,coords[i].lng);
marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:coords[i].caption
});
}
}
});
}

Show Button On Google Marker Drag

I wonder whether someone may be able to help me please.
I am using the code below to reverse geocode address details, in this case starting off with the OS Grid Ref.
Could someone perhaps tell me please how I would go about including code which upon the marker being dragged, a button called 'regenerateosgridref' would appear on the form.
(function reversegeocodeosgridref() {
var map, geocoder, latlng, marker;
window.onload = function() {
var myOptions = {
zoom: 6,
center: new google.maps.LatLng(54.312195845815246, -4.45948481875007),
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl: true,
mapTypeControlOptions: {
style: google.maps.MapTypeControlStyle.HORIZONTAL_BAR,
position: google.maps.ControlPosition.TOP_RIGHT
},
navigationControl: true,
navigationControlOptions: {
style: google.maps.NavigationControlStyle.ZOOM_PAN,
position: google.maps.ControlPosition.TOP_LEFT
},
scaleControl: true,
scaleControlOptions: {
position: google.maps.ControlPosition.BOTTOM_LEFT
}
};
map = new google.maps.Map(document.getElementById('map'), myOptions);
var form = document.getElementById('searchforlocationosgridref');
form.onsubmit = function() {
var lat = document.getElementById('osgb36lat').value;
var lng = document.getElementById('osgb36lon').value;
var latlng = new google.maps.LatLng(lat, lng);
getAddress(latlng);
return false;
}
}
function geocodePosition(pos) {
geocoder.geocode({
latLng: pos
},
function(responses) {
if (responses && responses.length > 0) {
updateMarkerAddress(responses[0].formatted_address);
} else {
updateMarkerAddress('Cannot determine address at this location.');
}
});
}
function updateMarkerAddress(str) {
document.getElementById('returnedaddress').value = str;
}
function getAddress(latlng) {
if (!geocoder) {
geocoder = new google.maps.Geocoder();
}
geocoder.geocode({
'latLng': latlng
}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (results[0]) {
map.setCenter(results[0].geometry.location);
if (!marker) {
map.setZoom(16);
marker = new google.maps.Marker({
map: map,
draggable: true
});
}
}
marker.setPosition(results[0].geometry.location);
google.maps.event.addListener(marker, function() {
updateMarkerAddress;
});
google.maps.event.addListener(marker, 'dragend', function() {
geocodePosition(marker.getPosition());
document.getElementById('osgb36lat').value = marker.position.lat();
document.getElementById('osgb36lon').value = marker.position.lng();
var point = marker.getPosition();
map.panTo(point);
});
latLng = [marker.position.lat(), marker.position.lng()].join(', ');
geocodePosition(marker.getPosition());
document.getElementById('returnedaddress').value = results[0].formatted_address;
}
})
}
})();
Many thanks and kind regards
Chris

Add a line in your marker dragend event that will show the button.
In your dragend event:
document.getElementById('regenerateosgridref').style.display = 'block';

Rather than add another button to my form. I have added some Javascript code that will update the OS Grid Reference as the marker is being dragged.
