JavaScript - Problem With Displaying Markers In Gmap
Similar TutorialsI'm not sure whether this is best posted here, or on a google maps api forum, but here goes: I have a site which uses a google map, and works well, like this: http://www.railwaysarchive.co.uk/eve...p?eventID=6684 I have built a version of that page which uses an OS map by default, but allows switching to a google map. It is he http://www.railwaysarchive.co.uk/osm...p?eventID=6684 The script uses a simple toggle as follows: Code: function toggleMap() {
// toggle map div visibility
var googlemap = document.getElementById("googlemap");
var OSmap = document.getElementById("OSmap");
if (OSmap.style.display!="block") {
// currently hidden, show
OSmap.style.display="block";
googlemap.style.display="none";
document.getElementById("maplink").innerHTML= "Switch to Google Map";
} else {
OSmap.style.display="none";
googlemap.style.display="block";
document.getElementById("maplink").innerHTML= "Switch to OS Map";
}
}
I was having trouble getting both maps to load their respective data when one was hidden, so both maps start out with display:block and then the gmap is hidden during the <body onload>. This system works great with Firefox and with Chrome, but in IE if you switch to the google map the tiles don't load. Can anyone help? Relevant code snippets are as follows: Code: <body onload="createOSAccidentSummaryMap(52.6566359591919, -3.14070984721184, 7); createAccidentSummaryMap(52.6566359591919, -3.14070984721184, 'accident', 13); toggleMap();">
function createAccidentSummaryMap(dblLatitude, dblLongitude, enumType, lngZoom) {
// creates a map with a single event marker, map type controls and full zoom controls
// and centers it on the event coordinates
if (GBrowserIsCompatible()) {
// checks for compatible browser
map = new GMap2(document.getElementById("googlemap"));
map.addControl(new GSmallZoomControl());
map.addControl(new GMapTypeControl());
map.addControl(new GScaleControl());
map.setCenter(new GLatLng(dblLatitude, dblLongitude), lngZoom);
map.enableDoubleClickZoom();
map.setMapType(G_HYBRID_MAP);
var icon = createEventIcon(enumType);
var point = new GLatLng(dblLatitude, dblLongitude);
var marker = new GMarker(point, icon);
map.addOverlay(marker);
}
}
Can anyone look at the link below, and tell me why the infoWindow displays the same xml marker node for each marker Thanks Lee http://www.hotels.seotra.com/ 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 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. 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! Hi, 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.

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 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 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...

Any help would be much appreciated! 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....

Help would be appreicated very much! I cannot combine the codes to save my life... I have a video (.wmv) that has markers in it one can access these markers in video players like "Windows Media Player" at "view" -> "file markers" I want to embed the video object in an HTML page and be able to let the user jump to these markers via JavaScript or such. I managed to do this with Internet Explorer ודןמע JavaScript but I can't get any other browser to access these markers or any timeline function for that matter. I need to be able to do so cross browser. any ideas? 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>

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? Hello all i'm stuck on the last part of my program. Basically it will generate the score and players position but it will no show the following: I'm also having trouble stopping the loop from going over 80 Now add code to your program which will: ! declare and initialise a variable to keep count of how many goes the player takes to get out; ! add one to this count every time the loop is repeated; ! write out the count in a suitable message at the end. Any help is very much appreciated. [CODE] var countMoves = 0; while (playersPosition <80) { playersScore = rollDie(); document.write('Sco ' + playersScore); playersPosition = playersScore + playersPosition; document.write(' squa ' + playersPosition); indexOfNumber = findIndexOf(playersPosition, specialSquaresArray); if (indexOfNumber != -1) { document.write(' ladder to square ' + connectedSquaresArray[indexOfNumber]); document.write('<BR>'); document.write('Sco ' + playersScore); playersScore = connectedSquaresArray[indexOfNumber] + playersScore; document.write(' squa ' + playersScore); playersPosition = playersScore; } document.write('<BR>'); } for (count =1; count <=array.length; count = count + 1) if(array[count] > array[countMoves]) { countMoves = count; } document.write('it took ' + indexOfNumber + 'goes to get out'); [CODE] Hi all, I have a code that will fetch out the data from database OnMouseOver. But it is working fine if don't add table on the div which will come OnMouseOver. If i try to show the fetched data in table then the code doesn't work. Please someone help me with this. Here is my code: Code:
<script type="text/javascript" language="JavaScript">
var cX = 0; var cY = 0; var rX = 0; var rY = 0;
function UpdateCursorPosition(e){ cX = e.pageX; cY = e.pageY;}
function UpdateCursorPositionDocAll(e){ cX = event.clientX; cY = event.clientY;}
if(document.all) { document.onmousemove = UpdateCursorPositionDocAll; }
else { document.onmousemove = UpdateCursorPosition; }
function AssignPosition(d) {
if(self.pageYOffset) {
rX = self.pageXOffset;
rY = self.pageYOffset;
} else if (document.documentElement && document.documentElement.scrollTop) {
rX = document.documentElement.scrollLeft;
rY = document.documentElement.scrollTop;
} else if (document.body) {
rX = document.body.scrollLeft;
rY = document.body.scrollTop;
}
if(document.all) {
cX += rX;
cY += rY;
}
d.style.left = (cX+10) + "px";
d.style.top = (cY+10) + "px";
}
function HideContent(d) {
if(d.length < 1) { return; }
document.getElementById(d).style.display = "none";
}
function ShowContent(d) {
if(d.length < 1) { return; }
var dd = document.getElementById(d);
AssignPosition(dd);
dd.style.display = "block";
}
function ReverseContentDisplay(d) {
if(d.length < 1) { return; }
var dd = document.getElementById(d);
AssignPosition(dd);
if(dd.style.display == "none") { dd.style.display = "block"; }
else { dd.style.display = "none"; }
}

Bullet points might help: When someone clicks on an image here (http://gta.kwivia.co.uk/gta-iv/), the rest of the images collapse and become invisible Below the image, some links appear Also, there will be a "show other images" button which will then show the rest of the images http://gta.kwivia.co.uk/gta-iv/ I will appreciate all solutions to this problem. If you need to know anything, simply ask me. Hello, for some reason this code isnt showing anything: Code: <span id = "message" style="color:black; font-size:12pt; font-family:arial,verdana,sans-serif"></span>

Anyone know why? Thanks Hello all, I'm trying to create a sub menu that displays based on what the user clicks on the main nav. Here's an image of what I'm trying to accomplish. The main nav is at the top right corner, when the click on one of the links, I want the sub nav to display in the gray area....how would I do this. Would it be through an if/else statement using document.getElementById with inner HTML? Or would there be a better way. I'm really trying to do this by myself, so please don't do it for me...just give me a couple of suggestions if you don't mind. THanks |
