JavaScript - Adding Marker Numbers Using Google Maps
I've been looking for a solid solution for how to add numbers to markers. Most that I've seen involve an asp page with a post back of an image based on the query string.
I am trying to do something like what MarkerClusterer does. Here is an example: http://google-maps-utility-library-v...e_example.html I've looked over their code and cant seem to pull out the part where it adds the numbers to the marker, I'm still new to jquery. Here is a link to the source code: http://google-maps-utility-library-v...erclusterer.js any help would be appreciated. Similar TutorialsHi i am building a gps tracker and i am having problems with the marker manager. I am pretty new to this stuff and i am sure my problem is quiet simple i just cant get my head around it. I posted my java script . If anyone can help it will be much appreciated. I am adding marker data from an xml file generated. I want to add a marker manager to the already existing markers generated to i add extra functionality on them. thanks for your time.

I am having a problem with google maps api. i have created a map which will place a marker on the location entered in a text field. There are two other fields on the page called latbox and lngbox which i want to be populated when the marker is initially created and when it is dragged. so far im just working on the dragged and cant get it working although trying multiple ways. Code: <script type="text/javascript">
var geocoder;
var map;
var marker=false;
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
}
function codeAddress() {
var address = document.getElementById("address").value;
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,

draggable: true
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
google.maps.event.addListener(marker, 'drag', function(event){

Any Help greatly appreciated hi, on my site: http://www.sbannister.co.uk/helix_site2/contact.html I am able to move my logo on my map, is there any way of locking it's position? thanks Right I have google maps connected to a database which holds stockists and their information. The user enters their postcode and radius and markers are put on the map of stockists in the radius of their postcode. I have this all working fine and the database chucks the information into an xml file fine. The problem im having is displaying the information in the pop up window of the marker. PHP Code: <script type="text/javascript"> //<![CDATA[ var map; var geocoder; function load() { if (GBrowserIsCompatible()) { geocoder = new GClientGeocoder(); map = new GMap2(document.getElementById('map')); map.addControl(new GSmallMapControl()); map.addControl(new GMapTypeControl()); map.setCenter(new GLatLng(54.622978,-2.592773), 5); } } function searchLocations() { var address = document.getElementById('addressInput').value; geocoder.getLatLng(address, function(latlng) { if (!latlng) { alert(address + ' not found'); } else { searchLocationsNear(latlng); } }); } function searchLocationsNear(center) { var radius = document.getElementById('radiusSelect').value; var searchUrl = 'phpsqlsearch_genxml.php?lat=' + center.lat() + '&lng=' + center.lng() + '&radius=' + radius; GDownloadUrl(searchUrl, function(data) { var xml = GXml.parse(data); var markers = xml.documentElement.getElementsByTagName('marker'); map.clearOverlays(); var sidebar = document.getElementById('sidebar'); sidebar.innerHTML = ''; if (markers.length == 0) { sidebar.innerHTML = 'No results found.'; map.setCenter(new GLatLng(54.622978,-2.592773), 5); return; } var bounds = new GLatLngBounds(); for (var i = 0; i < markers.length; i++) { var name = markers[i].getAttribute('name'); var address1 = markers[i].getAttribute('address1'); var address2 = markers[i].getAttribute('address2'); var town = markers[i].getAttribute('town'); var county = markers[i].getAttribute('county'); var postcode = markers[i].getAttribute('postcode'); var telephone = markers[i].getAttribute('telephone'); var distance = parseFloat(markers[i].getAttribute('distance')); var point = new GLatLng(parseFloat(markers[i].getAttribute('lat')), parseFloat(markers[i].getAttribute('lng'))); var marker = createMarker(point, name, address1, address2, town, postcode, telephone); map.addOverlay(marker); var sidebarEntry = createSidebarEntry(marker, name, town, distance); sidebar.appendChild(sidebarEntry); bounds.extend(point); } map.setCenter(bounds.getCenter(), map.getBoundsZoomLevel(bounds)); }); } function createMarker(point, name, address1, address2, town, postcode, telephone) { var marker = new GMarker(point); var html = '<b>' + name + '</b> <br/>' + address1 + '<br />' + address2 + '<br />' + town + '<br />' + postcode + '<br />' + telephone; GEvent.addListener(marker, 'click', function() { marker.openInfoWindowHtml(html); }); return marker; } function createSidebarEntry(marker, name, town, distance) { var div = document.createElement('div'); var html = '<b>' + name + '</b> (' + distance.toFixed(1) + ')<br/>' + town; div.innerHTML = html; div.style.cursor = 'pointer'; div.style.marginBottom = '5px'; GEvent.addDomListener(div, 'click', function() { GEvent.trigger(marker, 'click'); }); GEvent.addDomListener(div, 'mouseover', function() { div.style.backgroundColor = '#eee'; }); GEvent.addDomListener(div, 'mouseout', function() { div.style.backgroundColor = '#fff'; }); return div; } //]]> </script> Example Xml: PHP Code: <markers> <marker name="AVON ANGLING CTR" address1="348 WHITEHALL ROAD" address2="ST.

Would someone as be so kind to check my google maps script. For some reason the map is centering yet no marker (and info window) is being displayed. I'm (foolishly) using php to echo out the lat and long and the info window content yet everything seems to output okay...... Did a quick java de-bug and found the following error; Quote: Error: myLatlng is not defined Source File: xxx Line: 45 However the lat and lng are echo' out okay and the map is centered on the co-ordinates????

Hello, I have the code below but for some reason it only works when adding the marker to the map (map click). When I drag the marker around, the coordinates and closest address don't update. This code works if I add the marker straight in the initialize() function but not when I add it within the addListenerOnce for map click event. I want to be able to add 1 marker to the map, and update its address and coordinates when dragging the marker around. If someone can help me sort this out... Thanks in advance! Code: <html>

I've been trying for some time now to create some code which dynamically adds markers to a google map. I've now managed this but I still have a slight problem I think with the javascript side of things. I've included a snippet of the code which shows 2 markers on the map. They should be 2 different markers but they are the same, and the contents of the popup bubble should be each individual postcode, but they both show the same postcode. Does anyone have any ideas? Thanks Code:

Hi guys, Hopefully a really quick question. I'm a JS novice, and am looking for a way to output the coordinates of a Google maps marker into the value of two text fields, one for latitude and one for longitude. The code below is a simple location search which returns a result with a draggable marker. Currently, the coordinates in both text fields update when the location search is performed, but not when the marker is dragged to a new location afterwards. Does anyone know the code to simply update the coordinates each time the marker is dropped on a new location? Code: <html>

Many thanks in advance, I appreciate anyone who wants to help out! Hi, I am trying to add markers to Google Maps, they are working fine but some of the markers are of same location, thus Google Map will show only one marker for them. Is it possible to show all markers no matter if they are of same location. Help is much appreciated. Thanks Hi, I'm not sure where I have translated this incorrectly. I have one google map embedded on my page which works fine. But I wanted to add a second one. I thought the easiest way to do this would be to have a second page which is called later on with all the details on it for the second map. However although I think (this I presume is where I went wrong) I have replicated the instructions correctly the place holder for the second map just remains blank.

I've cut out the script that doesn't relate to this so I hope I haven't missed anything important. I'm having a little bit of trouble with setting up a Google map to add markers for events venues. The page is dynamically created using postcodes from a database which is why the code might look a little strange, but it's the only way I could find to make it work. However, I'm struggling to add any further functionality to the page. As you will see from the code attached I would like to add buttons to reset the map to it's initial state, plus buttons to show only the "O" markers or the "E" markers. Also, I would ideally only like to see the "O" markers when the page first loads. I know this is a lot to ask but could anyone please help.

If anyone can assist it would be most appreciated? I am using Dreamweaver (latest version)... This code here below when run produces a google map with a street address look up input. I am wanting to learn how to look up an address and submit this to resolve within the map, and also to insert a place holder... I'd like the look up box to sit within (and overlay) the map top left area - at the moment it sits below the map - which i guess is because I haven't inserted a frame??

You select a check box which then shows a marker on the map. My issue is, when you select and the marker is placed, I need the map to focus to that point, it currently embeds but doesn't focus. Is there a particular function I could use to achieve this? My current code is shown below: Code: var locations = [
// Longitude, Latitue, Content, Country Code, City Name
[51.481383, -3.114967, holidayOverlay, 'UK', 'Cardiff'],
[52.362393, 4.893379, holidayOverlay, 'NL', 'Amsterdam'],
[48.852314, 2.350089, holidayOverlay, 'FR', 'Paris'],
[40.18884, -3.716812, holidayOverlay, 'SP', 'Madrid'],
[53.800651, -4.064941, holidayOverlay, 'IT', 'Rome'],
[42.041134, 1.889648, holidayOverlay, 'SP', 'Costa Brava'],
[36.79334, 27.234421, holidayOverlay, 'GR', 'Kos'],
[37.014581, -7.933888, holidayOverlay, 'PT', 'Algarve'],
[28.358776, -14.05426, holidayOverlay, 'PT', 'Fuerteventura'],
[29.046854, -13.589973, holidayOverlay, 'SP', 'Lanzarote'],
];
// Only create marker when checked
for (i = 0; i < locations.length; i++) {
if (locations[i][4] == location) {
var marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][0], locations[i][1]),
map: map,
icon: plotImage
});
var title = locations[i][4];
var content = locations[i][2];
}
}

do i need to apply setInterval on the marker? how to apply it on the marker so it refresh every X second... please help for the solution.... I have some problems with intergrating google maps into my page I cant seem to get a marker to appear on my map. I have tried numerous methods but non seem to work. I have integrated the google maps on my main site, repositioned and re-sized. The code below is a test page i work on to get code to work. It's just a map on a page entire code: <!DOCTYPE HTML> <html> <head> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <style type="text/css"> html { height: 100% } body { height: 100%; margin: 25px; padding: 25px } #map_canvas { height: 100% } </style> <script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?key=AIzaSyDrxZnpYBNIwzBFVYaDY__BMONEjNEGZaI&sensor=false"> </script> <script type="text/javascript"> function initialize() { var myLatlng = new google.maps.LatLng(-25.363882,131.044922); var myOptions = { zoom: 4, center: myLatlng, mapTypeId: google.maps.MapTypeId.ROADMAP } var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);} var marker = new google.maps.Marker({ position: myLatlng, map: map, title:"Hello World!" }); </script> </head> <body onload="initialize()"> <div id="map_canvas" style="width:100%; height:100%"></div> </body> </html> can anybody tell my where i am going wrong and just the map appears with no marker? thanks I'm completely at a loss how to embed a map with the new google maps api setup. I found a snippet of code that I dropped in with some small database variables pulled in and was done. Then an error came that the API was no good. So I went in and set up an anaccount, got an api and now I just simply have no clue what their instructions are saying I need to do. Gah! Here's what I originally had: I now have a Client ID, client secret and stuff. But no clue how to set up this url, etc. Code: </script>
<script src="//maps.google.com/maps?file=api&v=2&key=AIzaSyD4iE2xVSpkLLOXoyqT-RuPwURN3ddScAI"
type="text/javascript"></script>
<script type="text/javascript">
function initialize() {
if (GBrowserIsCompatible()) {
var map = new GMap2(document.getElementById("map_canvas"));
map.setCenter(new GLatLng(<?php echo $c_row['location_longitude']; ?>,<?php echo $c_row['location_latitude']; ?>), 13);
// Add the latitude/longitude marker to the map
var point = new GLatLng(<?php echo $c_row['location_longitude']; ?>,<?php echo $c_row['location_latitude']; ?>);
map.addOverlay(new GMarker(point));
map.setUIToDefault();
}
}
</script>
<b>Map:<br><br><div id="map_canvas" style="width: 500px; height: 300px; z-index:4000;border-width:medium;border-color:#030;"></div></b>
I am using jMapping(http://vigetlabs.github.com/jmapping/) for using jQuery with google maps. What I'm trying to do is add an event listener so that when you click on a marker it will call a function I made within the jMapping function. Does anyone have any clues? everything I've tried doesn't work.
Hey I'm quite new at javascript and am currently in the process of creating a site that embeds google maps using an xml document. What I'm trying to do is categories the markers on my map. I am trying to make it so there are check boxes at the bottom and when i check the boxes, i.e. theatres, the markers will appear for the theatres and disappear when unchecked. Using some example code i have modified, i have so far got the maps to pickup the markers from the xml with the check boxes but the markers are all just on the page and the check boxes dont do anything and I am stuck as to of why. here's my code: Code: <!DOCTYPE HTML>
<html>
<head>
<title>Google Maps</title>
<script src="mykey"></script>
</head>
<body style="margin:0px; padding:0px;" onload="initialize()">
<table border=1>
<tr>
<td>
<div id="map" style="width: 550px; height: 450px"></div>
</td>
<td valign="top" style="width:150px; text-decoration: underline; color: #4444ff;">
<div id="side_bar"></div>
</td>
</tr>
</table>
<form action="#">
Theatres: <input type="checkbox" id="theatrebox" onclick="boxclick(this,'theatre')" />
Golf Courses: <input type="checkbox" id="golfbox" onclick="boxclick(this,'golf')" />
Tourist Information: <input type="checkbox" id="infobox" onclick="boxclick(this,'info')" /><br />
</form>
<script type="text/javascript">
_uacct = "UA-162157-1";
urchinTracker();

If anybody help with this and tell me where I am going wrong, it would be much appreciated. thanks Hi I have just started looking at the Google maps, and have atutorial that will get the co-ordinates. What I want this to do, is then populate two fields on a form one called longitude and one called latitude Code: function usePointFromPostcode(postcode, callbackFunction) {
localSearch.setSearchCompleteCallback(null,
function() {
if (localSearch.results[0]) {
var resultLat = localSearch.results[0].lat;
var resultLng = localSearch.results[0].lng;
var point = new GLatLng(resultLat,resultLng);
callbackFunction(point);
}else{
alert("Postcode not found!");
}
});
localSearch.execute(postcode + ", UK");
}
Any ideas/tips would be be much appreciated |
