JavaScript - Google Maps - Jump To Markers Help
Hello
I need some help with Google Maps please. Im using Google Maps API V3. So I can create a simple map but what I need is to have two markers (which are quite far apart) on the map. For example these markers are called 'Marker 1' and 'Marker 2'. Below the map I would have 2 links called for example 'Marker 1 link' and 'Marker 2 link'. When the map loads, 'Marker 1' is visible and centered. Now to move to 'Marker 2' on the map, I would click the link under the map. And vice versa. A good example is http://arts.brighton.ac.uk/contact-u...aculty-of-arts I tried but failed when I tried this guys answer on this website: http://stackoverflow.com/questions/2...utside-the-map Any help to create this is greatly appreciated! Similar TutorialsHi, not sure if this is quite the right forum to ask this, but it is a javascript function after all so I thought I'd give it a shot. Here's the problem: I have an array of latitude/longitude data. I need to make a marker appear on the map for each lat/lng pair. But it won't. If I ask the function to print out the coordinates instead of marking them on the, map, it works fine. I don't get an error message either way, so I'm stuck. The page displays the map but without any markers. Here's the code of the function that should add markers: Code: //adds markers to the map
function addMarkers(locarray) {
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locarray.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locarray[i][0], locarray[i][1]),
map: map
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent('some words');
infowindow.open(map, marker);
}
})(marker, i));
}
}
Here's the initialize function (called on body load): Code: function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = codeAddress("<?php echo $_POST['postal']; ?>");
var myOptions = {
zoom: 11,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
}
geocoder and map are declared as global variables. The codeAddress function returns lat and lng of the place I want to center the map around, it's been tested and works perfectly. And here is the script that declares the array and calls the addMarkers function: Code: <script type='text/javascript'>
var locations = [
[-33.890542, 151.274856],
[-33.923036, 151.259052],
[-34.028249, 151.157507],
];
addMarkers(locations)
</script>
Does anyone see anything wrong with this? I am trying to make google maps zoom to fit markers, I made this super simple example that should work but blows up when it comes time to create the LatLngList Array. I'm using this guys code that everyone says works:http://blog.shamess.info/2009/09/29/...e-maps-api-v3/ Code: <!DOCTYPE html>

Fellow Coders, I am trying to follow this tutorial (http://econym.org.uk/gmap/basic16.htm) What I would like to do is have in my XML file, a parameter for a total (some random number) and I want to plot a marker based on this number. So like, if the total="5" then marker would be red, if it was 10, marker would be green. I see in the tutorial that they are storing the possible markers in an array, I get that. What I don't know how to do is plot the markert depending on the value of the total field in the XML file. Hi guys. I have posted about this before on here but I'm still having a lot of issues. MY GOAL - I have a database with a bunch of items and each has latitude, longitude and a category (all the items are within 1 city). I want to have a page that will show a google map, display a marker based on the lat/lng and the image of the marker should be customized based on the category of the row. For example, some rows have a 'food' category and some have a 'health' category - I have specific images I want displayed for each image. I need a script that will plot a marker for each item in my db. I have never used Google maps API before and I'm thinking V3 is what I need to use. Can someone help fill in the code below? PHP Code: $query=mysql_query("SELECT * FROM table"); while($row=mysql_fetch_array($query)){ $lat=$row['lat']; $lng=$row['lng']; $category=$row['category']; //SET MARKER PICTURE TO $category //ADD MARKER TO MAP } Can anybody help out with the code? I don't know javascript that well and I have tried about 40 different things and get nothing but a blank page! THANK YOU SO MUCH Hi guys, so far any values recorded in my database are shown on the map: http://www.vfrflight.co.uk/new2/phpsqlajax_map_v3.html Code: <!DOCTYPE html >

Help would be appreicated very much! I cannot combine the codes to save my life... Firstly I know this is a PHP issue yet it is within javascript and IMO is the root cause of the problem. I'm trying to output markers from a search query of locations from my database, onto a Google Map (api v.3) using a tut I found http://tips4php.net/2010/10/use-php-...g-data-on-map/ When adding this to my page I'm getting Undefined index:errors. I have changed the variables in the php part of the script to suit my database yet have left everything else alone, cant figure out why I'm still getting a blank map???? Please help....

I pulled this code from Google's example section to make markers on a v3 Google Maps API (I have added my own lat/long points and corresponding event listeners, of course, but this is still the spirit of the code):
Code: <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var map;
function initialize() {
var map_center = new google.maps.LatLng(39.2,-84.479381);
var store1 = new google.maps.LatLng(39.112456,-84.574779);
var store2 = new google.maps.LatLng(39.314153,-84.261379);
var store3 = new google.maps.LatLng(39.197099,-84.667579);
var store4 = new google.maps.LatLng(39.16836,-84.479381);
var myOptions = {
zoom: 10,
center: map_center,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker1 = new google.maps.Marker({
position: store1,
map: map,
title:"Store 1"
});
var marker2 = new google.maps.Marker({
position: store2,
map: map,
title:"Store 2"
});
var marker3 = new google.maps.Marker({
position: store3,
map: map,
title:"Store 3"
});
var marker4 = new google.maps.Marker({
position: store4,
map: map,
title:"Store 4"
});
google.maps.event.addListener(marker1, 'click', function() {
map.set_center(store1);
map.set_zoom(16);
});
google.maps.event.addListener(marker2, 'click', function() {
map.set_center(store2);
map.set_zoom(16);
});
google.maps.event.addListener(marker3, 'click', function() {
map.set_center(store3);
map.set_zoom(16);
});
google.maps.event.addListener(marker4, 'click', function() {
map.set_center(store4);
map.set_zoom(16);
});
}
</script>
This works without fail, but when I try to use a javascript array to hold my values and loop my way through the marker creation like so: Code: <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var map;
function initialize() {
var map_center = new google.maps.LatLng(39.2,-84.479381);
var store_locations = new Array();
var temporary_stuff = new Array();
store_locations[0] = "39.112456,-84.574779";
store_locations[1] = "39.314153,-84.261379";
store_locations[2] = "39.197099,-84.667579";
store_locations[3] = "39.16836,-84.479381";
var myOptions = {
zoom: 10,
center: map_center,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
for(i=0;i<store_locations.length;i++){
var marker_string = "position: "+new google.maps.LatLng(store_locations[i])+", map: map, title:\"Store "+(i+1)+"\";";
temporary_stuff[i] = new google.maps.Marker(marker_string);
}
var markers = new Array();
for(i=0;i<temporary_stuff.length;i++){
var the_marker = "position: temporary_stuff[" + i + "], map: map, title:\"Store " + (i+1) + "\";";
markers[i]= new google.maps.Marker(the_marker);
}
}

I get a blank map. Here's a link to the test file: http://rowsdower.freehostia.com/map_test.php It's not throwing up any errors in Firefox's developer or in IE but there it sits, a blank map. I'm sure this isn't clean or optimized code, but it looks correct to me. I've color-coded the code above to show what "for" loops are being used to try to replace which code. Hopefully that makes this more sensible. I haven't even tried to add the listeners yet since I can't get the markers to appear. Can anyone tell me why this isn't working or point me in a more productive direction? Is there a better way already out there that I haven't noticed? I'm trying to show an array of markers which, when clicked, will show an infowindow and also a circle with a radius, the size of which is also part of the array. I've got as far as showing the markers, the infoboxes and the circles, but am struggling with toggling the circles. I haven't quite made up my mind if I want the circles to all be initially on or off, I guess that depends how many I end up with... Here's what I have so far: - Code: <html xmlns="http://www.w3.org/1999/xhtml">

Any help would be much appreciated! I am no javascript coder so apologies for what may be a simple issue, I have a php page that pulls MySQL marker locations I have tried using examples for bounds etc but the map isn't centered or zoomed, it instead seems to center over the Pacific and minimum zoom level (For the url below it should be centered over the Devon region of the UK and zoomed in) the page where you can see the end result is he http://www.peugeotcentral.co.uk/modu...tches&Region=1 I did have some issues in my code whereby I was using deprecated function of GPoint for passing locations but one of the group mods kindly pointed this out and this was replaced with GLatLng but the fault is still there any help much appreciated, I do have the source code for the php if required For my Javascript class, we are to take a code from the book and add on to it. In this code, I decided to add custom markers and info windows for each location. I got the info windows to work but they are the same for each marker. How can I fix this? Here is what I have: Code: <script>

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. This is the code for my called page with the instructions for the second map: PHP Code: <?php echo $_POST['Map'] . '<br />'; ?> <div id="placemap_canvas"></div> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <style type="text/css"> html {height:250px} body {height:250px} #placemap_canvas {width:100%; height:150px;} </style> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true" /> </script> <script type="text/javascript"> var latlng = new google.maps.LatLng ( <?php include("dbconnect.php"); $result = mysql_query("SELECT * FROM regions WHERE RegionPId='{$_POST['Map']}'"); while($row = mysql_fetch_array($result)){ echo $row['maplink']; } mysql_close($con); ?> ); var myOptions = { zoom: 4, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("placemap_canvas"), myOptions); } </script> And this is the script of the main page, just in case I would be better off keeping them both in one place. Code: <head>
<script type="text/javascript">
function loadSubPlace(File,ID,Msg,Eile,EID,Esg){
loadXMLDoc1(File,ID,Msg);
var mimer = setTimeout(function(){loadXMLDoc1(Eile,EID,Esg)},5000);

I've cut out the script that doesn't relate to this so I hope I haven't missed anything important. Hey all I'm quite a newbie at javascript and I'm trying to have links to google maps markers. I have a page with my embeded google maps on it and some markers. What I'm basically looking to do is have a web page with a menu down the side and when you click the menu items, the google maps markers would pop up on the map. For example, city attractions down a side menu and when you click say restaurants, the markers would pop up the location restaurants in a certain place, then you could click pubs and the restaurant markers would dissapear and the pub markers would appear. Can anyboy help me with this or even direct me to some code that would help. Thanks all. 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>

type="text/javascript"></script>

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']; ?>);

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 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.
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 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>

its all working well but i need to use it differently. Is there a way to make the form submit automatically , i already have the address and i will <php> it from my database. i want that the map will show in the page as soon as the user clicked on an ad(real estate ad). Basically what we need here is: To know how to call the functions and give the address from the database. <body onload="initialize()" onunload="GUnload()"> <form action="#" onsubmit="showAddress(this.address.value); return false"> <p> <input type="text" size="60" name="address" value="1600 Amphitheatre Pky, Mountain View, CA" /> <input type="submit" value="Go!" /> </p> <div id="map_canvas" style="width: 500px; height: 300px"></div> </form> </body> Is there a way just to use this command without the form onsubmit="showAddress(this.address.value); return false">? And give the address as a variable ? and when the page is uploading it will have already passed the address and the map will show Danny Hi, Not sure how difficult this will be but im working on a javascript/HTML5 game, and thought it would be interesting to allow for people to add their score to a google map at their location. I can get the google map and allow people to add their own markers but i dont no how i would store them, and then reload them when someone plays the game. any ideas? Thanks, Luke Hey all, I was wondering if someone would be able to help me with a problem I've been having. I'm attempting to find coordinates for several addresses at a time. I'm using a for-loop to loop through an array of addresses. I figured it would be best to have a separate function to evaluate the coordinate given an address, and just call it in every loop. Note that my code below is simplified (I removed the for loop because that's not where I'm having trouble). I know that the issue is probably because I'm trying to return a value from an anonymous function... I tried making the variable global, I tried having a return line from within the anonymous function, nothing has worked... any tips? Thanks -- Code follows Code: function initialize(){
var geocoder = new google.maps.Geocoder(); // creating a new geocode object
var locCood = findcood('44106', geocoder);
}
function findcood(addr, geocoder)
{
var cood;
if (geocoder) {
geocoder.geocode({'address': addr}, function(results, status, cood){
if (status == google.maps.GeocoderStatus.OK)
cood = results[0].geometry.location;
else {
cood = null;
alert("Geocode was not successful for the following reason: " + status);
}
});
}
else
{
alert("No Geocode");
cood = null;
}
alert(cood);
return cood;
}
