I will explain. I managed to have a draggable pin on a map. I want to retrieve the coordinates of this point and put them into two fields: Latitude and Longitude. These coordinates will later be send to a SQL table via PHP.
Here is an example of what I intend to do, but instead of several pins, it's just one and it's draggable. The problem is: I'm not even able to display the coordinates of the initial point. And of course when the user moves the pin, I want the coordinates to change as well in the fields.
I hope I made myself clear. What did I do wrong? Should I use the Geocoding service?
Here goes the JS:
<script type="text/javascript">
var map;
function initialize() {
var myLatlng = new google.maps.LatLng(40.713956,-74.006653);
var myOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker = new google.maps.Marker({
draggable: true,
position: myLatlng,
map: map,
title: "Your location"
});
google.maps.event.addListener(marker,'click',function(overlay,point){
document.getElementById("latbox").value = lat();
document.getElementById("lngbox").value = lng();
});
}
</script>
And the HTML:
<html>
<body onload="initialize()">
<div id="map_canvas" style="width:50%; height:50%"></div>
<div id="latlong">
<p>Latitude: <input size="20" type="text" id="latbox" name="lat" ></p>
<p>Longitude: <input size="20" type="text" id="lngbox" name="lng" ></p>
</div>
</body>
</html>
Either of these work
google.maps.event.addListener(marker, 'click', function (event) {
document.getElementById("latbox").value = event.latLng.lat();
document.getElementById("lngbox").value = event.latLng.lng();
});
google.maps.event.addListener(marker, 'click', function (event) {
document.getElementById("latbox").value = this.getPosition().lat();
document.getElementById("lngbox").value = this.getPosition().lng();
});
You might also consider using the dragend event also
google.maps.event.addListener(marker, 'dragend', function (event) {
document.getElementById("latbox").value = this.getPosition().lat();
document.getElementById("lngbox").value = this.getPosition().lng();
});
Look at the official code sample from Google Maps API reference:
http://gmaps-samples-v3.googlecode.com/svn/trunk/draggable-markers/draggable-markers.html
The code that is actually working is the following:
google.maps.event.addListener(marker, 'drag', function(event){
document.getElementById("latbox").value = event.latLng.lat();
document.getElementById("lngbox").value = event.latLng.lng();
});
It would be better if the map could be re-centered once the pin is dropped. I guess it can be done with map.setCenter() but I'm not sure where I should put it. I tried to put it right before and right after this piece of code but it won't work.
Google Maps V3 Example. Here's a working example of a user dropping a single pin, replacing a dropped pin with new pin, custom pin images, pins that populate lat/long values in a FORM FIELD within a DIV.
<html>
<body onLoad="initialize()">
<div id="map_canvas" style="width:50%; height:50%"></div>
<div id="latlong">
<p>Latitude: <input size="20" type="text" id="latbox" name="lat" ></p>
<p>Longitude: <input size="20" type="text" id="lngbox" name="lng" ></p>

Check this fiddle
In the following code replace dragend with the event you want. In your case 'click'
google.maps.event.addListener(marker, 'dragend', function (event) {
document.getElementById("defaultLatitude").value = event.latLng.lat();
document.getElementById("defaultLongitude").value = event.latLng.lng();
});
google.maps.event.addListener(marker, 'dragend', function (event) {
document.getElementById("latbox").value = this.getPosition().lat();
document.getElementById("lngbox").value = this.getPosition().lng();
});
worked well for me.. Thanks..
var zoomLevel = map.getZoom();
var pos = (event.latLng).toString();
$('#position').val(zoomLevel+','+pos); //set value to some input

I have working java script Google Map Api v3 with Geocoding.
When I type for example post code in search box I can select address from list. If I will do same thing and press ENTER nothing is happening. How to modify code?
<input id="address" type="textbox">
Java script code:
var geocoder;
var map;
var marker;
function initialize(){
//MAP
var latlng = new google.maps.LatLng(51.469186, -0.361166);
var options = {
zoom: 11,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), options);
//GEOCODER
geocoder = new google.maps.Geocoder();
marker = new google.maps.Marker({
map: map,
draggable: false
});
//CIRCLE
var circle = new google.maps.Circle({
map: map,
center: new google.maps.LatLng(51.469186, -0.361166),
fillColor: '#204617',
fillOpacity: 0.2,
strokeColor: '#6DE953',
strokeOpacity: 0.4,
strokeWeight: 2
});
circle.setRadius(10000);
}
$(document).ready(function() {
initialize();
$(function() {
$("#address").autocomplete({
//This bit uses the geocoder to fetch address values
source: function(request, response) {
geocoder.geocode( {'address': request.term }, function(results, status) {
response($.map(results, function(item) {
return {
label: item.formatted_address,
value: item.formatted_address,
latitude: item.geometry.location.lat(),
longitude: item.geometry.location.lng()
}
}));
})
},
//This bit is executed upon selection of an address
select: function(event, ui) {
var location = new google.maps.LatLng(ui.item.latitude, ui.item.longitude);
marker.setPosition(location);
map.setCenter(location);
}
});
document.getElementById("address").focus();
});
});
I have try adding search button:
<input id="search" type="button" value="Search" onclick="codeAddress()">
and adding function codeAddress() to Java Script but I must have done something wrong as that didn't worked.
Working (without ENTER) jsfiddle
you can try this maybe you'll get some ideas. https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete-addressform
they are also using geocode, so you can refer the code.
I'm not a 100% certain what you are doing wrong, since you did not post all the code. But this example works (I tested in FF):

I've followed the search and zoom example from here: https://developers.google.com/fusiontables/docs/samples/search_and_zoom
and I've managed to get the "Reset" button to work, but the "Search" button isn't working. I wondered if it was because I am using 2 layers, but I don't know how to correct by java script if that is that case. Any help appreciated. Thanks.

I get a "geocoder is undefined" error". Because it isn't defined.
One way to fix it would be to add this to the global scope (just before your initialize function):
var geocoder = new google.maps.Geocoder();
Or you could do it the way it is done in the example you used, it is inside the initialize function there.
working example
Having successfully followed some Fusion Map examples, with a little help from people here. I'm trying to do something I've been able to find an example of...
My map contains 3 layers, but I only want to show 2 at a time. I've therefore added a drop down box at the bottom so that you can switch between 2 of the maps. I've added a variable "SecondLayerMap", and I think (i've at least tried) to get the drop down box to change this variable. I'd never written any Java (or any other programming language) until 3 weeks ago, so it's been a steep learning curve!
[One method I've seen some people use in a similar situation has been to use 1 fusion table, but switch between data in different columns. I don't think I can do this because the geodata in each table is different and I don't want them both displayed at the same time.]
The next step will be to change one of the legends with the switch in map, but I'll take what i learn from this problem, before tackling that one...
Thanks for your help.

Hi this is my first post here..
I have been playing around with google maps trying to make a list of campsites in France.
I have got to the point of reading an xml file of the data
Loading the map and clustering the results and it all works but very slow.
Q1 Is there a limit on the number of markers you can render even using the clusterer (there are >7000 records at the moment)
Q2
Is there anything obviously wrong with the code I have so far:

This article may help. A tile based solution (FusionTables, KmlLayer, or a server based custom map) will render more quickly than native Google Maps API v3 objects, even with clustering. You may be seeing the transfer and processing time of the xml file.
dear professionals.
I want to make info window for each markers on google maps.
My code:
google.maps.event.addListener(marker, 'click', function() {
new google.maps.InfoWindow({content: content}).open(map, marker);
});
show infowindow only for last marker.
Please, give me example or link to tutorial.
This is a modification of my answer to this question: Maps API Javascript v3 how to load markers with a mouse click
It loads an array of markers with info windows, and displays the last one added.
