function popupDirections(marker) {

google.maps.event.addListener(marker, 'click', function() {

I write this function in order to show the information of place name, street number, or somethings else, but the problem is that I don't know how to get that information to display on the pop up. Any help would be appreciated.
may be you want to try this, this my code that have a element info windows from JSON. but if you only want to write your infowindow, just write it like as tag javascript. in my case, my element of info window, i get from database.
function initialize(){
var x = new Array();

var customer_name = new Array();
var cp_rayon_name = new Array();
var icon = new Array();
var photo = new Array();

If I put my code in JS the code works but I need to put in PHP file in future I want to echo some data from database. The error I have in console is Uncaught SyntaxError: Unexpected token< . Why is working if the file type is JS and why is not working on PHP file type? What cand I do?
You need to close php tag before script and open in after script like this
<?php
//some php code
?>
<script>
...
..
</script>
<?php
//php code
?>
I have just loaded the following code into my webpage and after many hours of troubleshooting, I can't get the Markers to show up?
I have confirmed that the parsing php file is working.

This is incorrect:
SetMap: map_canvas,
Should be (see MarkerOptions in the documentation):
map: map,
corrected marker constructor:
var marker = new google.maps.Marker({
map: map,
position: point,
icon: icon.icon
});
Add the parsing of the XML into the initialize function, so map is valid when you add the markers:
function initialize() {
var mapCanvas = document.getElementById('map_canvas');
var mapOptions = {
center: new google.maps.LatLng(0,0),
zoom: 4,
mapTypeId: google.maps.MapTypeId.HYBRID
}
var map = new google.maps.Map(mapCanvas, mapOptions);
downloadUrl("example.xml", function(data) {
var xml = data.responseXML;
var markers = xml.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
var id = markers[i].getAttribute("id");
var name = markers[i].getAttribute("name");
var icao = markers[i].getAttribute("icao");
var type = markers[i].getAttribute("type");
var elev = markers[i].getAttribute("elev");
var conname = markers[i].getAttribute("contactname");
var connum = markers[i].getAttribute("contactnum");
var point = new google.maps.LatLng(
parseFloat(markers[i].getAttribute("lat")),
parseFloat(markers[i].getAttribute("lng")));
var html = "<b>" + name + "</b> - " + icao + "<br/>" + conname + " - " + connum;
var icon = customIcons[type] || {};
var marker = new google.maps.Marker({
map: map,
position: point,
icon: icon.icon
});
bindInfoWindow(marker, map, infoWindow, html);
}
});
}
working example (using one of my existing xml files, since you didn't provide any example data)
You have additional problems with the call to bindInfoWindow and its definition (map_canvas, should be map)
I have a set of markers, and when clicked on a marker there is a button that gets directions. The problem is that it only gives directions to the last loaded marker from the xml, not to each marker individually. Here is my code, maybe someone can tell what I'm doing wrong. Thank you.

I globally defined every variable necessary for directions:
var map;
var point;
var directionsDisplay;
var directionsService;
var marker;
var myLatLng;
var marklat;
var marklong;
var markers;
var DirLat;
var DirLng;
created a button for the function, and set in content which is visible in the infowindow:
var content = "<button onclick='getDir();'>Get Directions</button>";
Next I created hidden input fields in the map page, and assigned values of Latitude and Longitude of the markers that are clicked.
document.getElementById('iLat').value = marker.getPosition().lat().toFixed(6);
document.getElementById('iLng').value = marker.getPosition().lng().toFixed(6);
The directions function getDir pulls these values for the destination, myLatLng is the current location of the user:
function getDir(){
directionsDisplay.setMap(map);
var start = myLatLng;
var LatDir = document.getElementById('iLat').value;
var LngDir = document.getElementById('iLng').value;
var end = new google.maps.LatLng(LatDir,LngDir);
var request = {
origin:myLatLng,
destination:new google.maps.LatLng(LatDir,LngDir),
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function(result, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(result);
}
});
}

Having trouble adding links that will center and open an info window on my google map. The markers and their info windows work fine within the map itself.
The real problem is constructing an object that my onclick function can reference properly. My object oriented Javascript knowledge is shaky and I'm just not seeing the solution.
The map is loaded via a function that's called on page load and I have a seperate function that's called on click of an href within the page.
Code is below.
function addMap(addressesJSON, id){
var addresses = eval('(' + addressesJSON + ')');
var cenLat = 41.677389;
var cenLng = -72.384294;
var latLow = 41.4;
var lngLow = -72.8;
var latHigh = 41.8;
var lngHigh = -71.9;
if (addresses.length){
for (var i in addresses){
addresses[i].lat = parseFloat(addresses[i].lat);
addresses[i].lng = parseFloat(addresses[i].lng);
if (i == 0){
latLow = addresses[i].lat;
latHigh = addresses[i].lat;
lngLow = addresses[i].lng;
lngHigh = addresses[i].lng;
} else {
if (addresses[i].lat < latLow){
latLow = addresses[i].lat;
}
if (addresses[i].lat > latHigh){
latHigh = addresses[i].lat;
}
if (addresses[i].lng < lngLow){
lngLow = addresses[i].lng;
}
if (addresses[i].lng > lngHigh){
lngHigh = addresses[i].lng;
}
}
address = "<span style=\"color: #0000ff\">" + addresses[i].name + "</span><br/>" + addresses[i].address + "<br/>Directions: To - From";
addresses[i].address = address;
}
cenLat = (latLow + latHigh) / 2;
cenLng = (lngLow + lngHigh) / 2;
}
var mapOptions = {
center: new google.maps.LatLng(cenLat, cenLng),
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
// Display a map on the page
var map = new google.maps.Map(document.getElementById(id), mapOptions);
var bounds = new google.maps.LatLngBounds();
var infowindow = new google.maps.InfoWindow();
for (var i in addresses){
var letter = addresses[i].letter;
var data = addresses[i].address;
var myLatlng = new google.maps.LatLng(addresses[i].lat, addresses[i].lng);
var latlng = new google.maps.LatLng(addresses[i].lat, addresses[i].lng);
bounds.extend(latlng);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: addresses[i].name,
icon: "http://maps.google.com/mapfiles/marker" + letter + ".png"
});
(function (marker, data) {
google.maps.event.addListener(marker, "click", function () {
// Center on marker
map.setCenter(marker.getPosition());
// Set the data for the info window
infowindow.setContent(data);
// show the infowindow
infowindow.open(map, marker);
});
})(marker, data);
}
map.fitBounds(bounds);
}
And the function that's fired onclick that I want to open the corresponding infowindow.
function moveCenter(lat, lng, letter){
google.maps.event.trigger(marker[letter], "click");
}
Any help on how to build a marker object array and have it be seen by my moveCenter function would be greatly appreciated.
Looks like you just need to add this line to your code:
markers[letter] = marker;
and change your function:
function moveCenter(lat, lng, letter){
google.maps.event.trigger(markers[letter], "click");
}
(make sure the markers array is in the global scope)
markers = [];
function addMap(addressesJSON, id){
var addresses = eval('(' + addressesJSON + ')');
var cenLat = 41.677389;
var cenLng = -72.384294;
var latLow = 41.4;
var lngLow = -72.8;
var latHigh = 41.8;
var lngHigh = -71.9;
if (addresses.length){
for (var i in addresses){
addresses[i].lat = parseFloat(addresses[i].lat);
addresses[i].lng = parseFloat(addresses[i].lng);
if (i == 0){
latLow = addresses[i].lat;
latHigh = addresses[i].lat;
lngLow = addresses[i].lng;
lngHigh = addresses[i].lng;
} else {
if (addresses[i].lat < latLow){
latLow = addresses[i].lat;
}
if (addresses[i].lat > latHigh){
latHigh = addresses[i].lat;
}
if (addresses[i].lng < lngLow){
lngLow = addresses[i].lng;
}
if (addresses[i].lng > lngHigh){
lngHigh = addresses[i].lng;
}
}
address = "<span style=\"color: #0000ff\">" + addresses[i].name + "</span><br/>" + addresses[i].address + "<br/>Directions: To - From";
addresses[i].address = address;
}
cenLat = (latLow + latHigh) / 2;
cenLng = (lngLow + lngHigh) / 2;
}

First, I'm using the library from : http://www.pittss.lv/jquery/gomap/examples/marker.php,
and I'm using a webservice to get data.
I would like to locate these informations on the map, but i can't know before, how many elements I will have to create.
To get data I have this code :
$('#default-search').submit(function () {
var gomap_marker = [];
var search_where = $('#search-where').val();
if ($('#search-where').val() == "")
search_where = "-1";
$.ajax({
url: "http://my_url.com/",
contentType: "json",
data: {
city: search_where
},
success: function (data) {
//List received data
$.each(data, function (index, item) {
//create an array with data
gomap_marker.push({
id: item.Id,
address: item.Street + ', ' + item.ZipCode + ' ' + item.City,
icon: 'images/marker.png',
group: 'toshow',
html: '' + item.Street + ', ' + item.ZipCode + ' ' + item.City + ''
});
}); // END - $.ajax success each
// valid test
for (var i = 0; i < gomap_marker.length; i++) {
alert('1 - ' + gomap_marker[i].id + gomap_marker[i].address + gomap_marker[i].html);
}
// reset the map for each request
$("#map").removeData();
alert('Test');
// map init + markers
jQuery('#map').goMap({
maptype: 'ROADMAP',
zoom: 13,
scaleControl: true,
scrollwheel: false,
markers: gomap_marker
});
}, // END - $.ajax success
error: function () { alert("simple request goes wrong"); }
}); // END - $.ajax
return false;
}); // END - default-search
Only the first row of my array create a marker on the map. I don't understand how to set the others.
I would like to use $.goMap.createMarker instead of creating an array and reset the map, but I had the same problem : only the first row created a marker on the map.
Regards,
emm First create an array of lat,long
var data = new Array();
data[0] = new Array();
data[0][0] = 'FOOD'; //name
data[0][1] = '23,23';//coordinates(lat,lng)
function HTMLMarker( place ) {
this.name = place[0];
var latLngStrings = place[1].split(',');
var lat = +latLngStrings[0];
var lng = +latLngStrings[1];
this.pos = new google.maps.LatLng( lat, lng );
}
HTMLMarker.prototype = new google.maps.OverlayView();
HTMLMarker.prototype.onRemove = function () {};
HTMLMarker.prototype.onAdd = function () {
var div = this.div = document.createElement('DIV');
div.className = "htmlMarker";
div.innerHTML = ''+this.name+'';
var panes = this.getPanes();
panes.overlayImage.appendChild(div);
};
HTMLMarker.prototype.draw = function () {
var overlayProjection = this.getProjection();
var position = overlayProjection.fromLatLngToDivPixel(this.pos);
var panes = this.getPanes();
this.div.style.left = position.x - 30 + 'px';
this.div.style.top = position.y - 48 + 'px';
};
function initialize() {
var myLatLng = new google.maps.LatLng(23,23);
var mapOptions = {
zoom: 15,
center: myLatLng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var gmap = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
for (var i = 0; i < data.length; i++) {
addMarker( data[i] );
}
function addMarker( place ) {
var htmlMarker = new HTMLMarker( place );
htmlMarker.setMap(gmap);
}
}
google.maps.event.addDomListener( window, 'load', initialize );
This should work!!
I am creating the array with php:
<script>
<?php $i = 0;
foreach($places as $place) {
$pins = $place['pins']; //coordinates
$name = $place['name'];
echo "data[$i] = new Array();\n";
echo "data[$i][0] = '" .$name. "';\n";
echo "data[$i][1] = '" .$pins. "';\n";
$i++;
} ?>
</script>
ALSO In css add this
.htmlMarker {
position: absolute;
}
