Google maps marker - infowindow

I need to in InfoWindow show match.offer.text.
Each marker has a different match.offer.text.
This is my code:
var markerImageURL, lat, lng;
if (myoffer) {
markerImageURL = 'assets/img/markers/marker_my.png';
lat = match.lat;
lng = match.lng;
} else {
markerImageURL = 'assets/img/markers/marker_' + match.strength + '.png';
lat = match.offer.lat;
lng = match.offer.lng;
}
var marker = new google.maps.Marker({
position: new google.maps.LatLng(lat, lng),
map: window.googleMap,
icon: {
size: new google.maps.Size(54,56),
url: markerImageURL
},
draggable: false,
visible: true
});
var infowindow = new google.maps.InfoWindow({
content: match.offer.text,
maxWidth: 300
});
window.googleMapMarkers.push(marker);
if(!myoffer) {
window.MVC.Events.GoogleMap.prototype.showInfoWindow(marker, infowindow, match);
}
Event triggered after clicking on the marker:
marker.addListener('click', function() {
infowindow.open(window.googleMap, marker);
}
Please, help me.

The content is applied to the marker on Open therefore your code will apply the content in last item in your loop to all markers, in your openWindow function add the content to a single infoWindow object i.e.
Also the Maps API has its own event wrapper for the click event
function initMarkers(){
//create markers
var marker = new google.maps.Marker();
google.maps.event.addListener(marker, 'click', openInfoWindow(marker, i));
}
var infowindow = new google.maps.InfoWindow();
function openInfoWindow(marker,index){
return function(e) {
//Close other info window if one is open
if (infowindow) {
infowindow.close();
}
var content = marker.offer.text;
infowindow.setContent(content);
setTimeout(function() {
infowindow.open(map, marker);
}, 200);
}
}

Google maps individual marker infowindow - how to?

I have this working multy markers script. Markers are printed on the map but when I click on any marker I can see same info window.. Something wrong in this loop:
function bindInfoWindow(marker, map, infowindow, content) {
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(content);
infowindow.open(map, marker);
});
}
function initialize() {
var map;
var locations = <?php echo json_encode($location); ?>;
var bounds = new google.maps.LatLngBounds();
var mapOptions = {
mapTypeId: 'roadmap'
};
// Display a map on the page
map = new google.maps.Map(document.getElementById("googlemap"), mapOptions);
// Multiple Markers
var markers = locations;
// Display multiple markers on a map
var infoWindow = new google.maps.InfoWindow();
// Loop through our array of markers & place each one on the map
for( i = 0; i < markers.length; i++ ){
loc_array = markers[i].split(",");
var position = new google.maps.LatLng(loc_array[1], loc_array[2]);
bounds.extend(position);
marker = new google.maps.Marker({
position: position,
map: map,
draggable: false,
raiseOnDrag: true,
title: loc_array[0]
});
// Info Window Content
content=loc_array[0] + " - <a class='ac' onclick='move("+ loc_array[4] +");' href='#'>" + <?php echo json_encode($lang['view_profile']);?> + "</a><span class='p'>" + <?php echo json_encode($lang['phone']);?> + ": " + loc_array[6] + " </span><span class='p'>" + <?php echo json_encode($lang['address']);?> + ": " + loc_array[5] + ", " + loc_array[7] + ", " + loc_array[8] + "</span>";
bindInfoWindow(marker, map, infoWindow, content);
//infowindow = new google.maps.InfoWindow();
console.log(content);
// Allow each marker to have an info window
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infoWindow.setContent(content);
infoWindow.open(map, marker);
}
})(marker, i));
// Automatically center the map fitting all markers on the screen
map.fitBounds(bounds);
}
bounds.extend(marker.position);
// Override our map zoom level once our fitBounds function runs (Make sure it only runs once)
var boundsListener = google.maps.event.addListener((map), 'bounds_changed', function(event) {
map.fitBounds(bounds);
google.maps.event.removeListener(boundsListener);
});
}
When I print individual info in console I can see different info windows, but on the map all come same:
console.log(content);
I call initialize() on body load
Please help where I am wrong, Thanks !

First of all declare infowindow globally in following way:
var infoWindow = new google.maps.InfoWindow();
Then after creating marker and content string just call this function:
bindInfoWindow(marker, map, infoWindow, content);
This is the definition of function bindInfoWindow()
function bindInfoWindow(marker, map, infowindow, content) {
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(content);
infowindow.open(map, marker);
});
}

Google Maps - center map on marker click

I have the following code for placing several markers on a google map.
What I now want to do is when the user clicks on a marker it zooms in and then centers the map to the marker position (this is the bit that's not working - towards the end of the code in the setMarkers function).
Any ideas?
var infowindow = null;
var sites = [];
var partsOfStr = [];
var partsOfStr2 = [];
var bounds;
$(document).ready(function () {
$("select[id*='coordList']").find("option").each(function () {
partsOfStr = $(this).val().split(',');
partsOfStr2 = $(this).text().split('^');
sites.push([partsOfStr2[0], parseFloat(partsOfStr[0]), parseFloat(partsOfStr[1]), partsOfStr[2], partsOfStr2[1], partsOfStr2[2], partsOfStr2[3], partsOfStr[3], partsOfStr[4], partsOfStr[5]]);
});
initialize();
});
function initialize() {
bounds = new google.maps.LatLngBounds();
var mapOptions = {
zoom: 6,
center: new google.maps.LatLng(54.57951, -4.41387),
scrollwheel: false,
mapTypeId: google.maps.MapTypeId.HYBRID
}
var map = new google.maps.Map(document.getElementById('map'), mapOptions);
setMarkers(map, sites);
infowindow = new google.maps.InfoWindow({
content: "loading..."
});
google.maps.event.addListener(infowindow,'closeclick',function(){
map.setCenter(new google.maps.LatLng(54.57951, -4.41387));
map.setZoom(6);
});
}
function setMarkers(map, markers) {
for (var i = 0; i < markers.length; i++) {
var sites = markers[i];
var siteLatLng = new google.maps.LatLng(sites[1], sites[2]);
var marker = new google.maps.Marker({
position: siteLatLng,
map: map,
title: sites[0],
html: "<div class='mapDesc'>content here...</div>"
});
google.maps.event.addListener(marker, "click", function () {
infowindow.setContent(this.html);
infowindow.open(map, this);
map.setCenter(marker.getPosition()); // NOT WORKING!!!!!!!
map.setZoom(10);
});
bounds.extend(new google.maps.LatLng(sites[1], sites[2]));
map.fitBounds(bounds);
}
}

marker is left pointing to the last marker added. Either use function closure or "this" like you did for the infowindow:
google.maps.event.addListener(marker, "click", function () {
infowindow.setContent(this.html);
infowindow.open(map, this);
map.setCenter(this.getPosition());
map.setZoom(10);
});

google.maps.event.addListener(marker, "click", function (evt) {
infowindow.setContent(this.html);
infowindow.open(map, this);
map.setCenter(evt.latLng);
map.setZoom(10);
});
that will working in my own app

How to set a popup on markers with Google Maps API?

I have this code where I display and set all my markers. How can I add a popup with some information on markers with this code? I add "i" variable on text, but it sets on all markers popup with "test - 723", where 723 is last value of the "i" variable. What is wrong?
for (var i = 0; i < arraylng.length-1; i++) {
var marker = new google.maps.Marker({
position: new google.maps.LatLng(arraylng[i], arraylat[i])
});
var infowindow = new google.maps.InfoWindow({
content: " "
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent('test: ' + i + '');
infowindow.open(map, this);
});
markers.push(marker);
}

First, change the loop condition to i < arraylng.length. Right now it is not capturing the last element of your array.
JavaScript variables works with function scope so you need to call a function for each marker listener to create the correct variable references. You can use an anonymous function, as seen here, or define a function for creating the click listener:
Multiple infoWindows:
function makeInfoWindowEvent(map, infowindow, marker) {
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map, marker);
});
}
Most likely you will not want more than one InfoWindow open at the same time, because it is annoying to have to click on the close x. Then you will only want one InfoWindow object, and set the content as the marker is clicked:
Single InfoWindow:
...
var infowindow = new google.maps.InfoWindow();
for (var i = 0; i < arraylng.length-1; i++) {
var marker = new google.maps.Marker({
position: new google.maps.LatLng(arraylng[i], arraylat[i]),
map: map
});
makeInfoWindowEvent(map, infowindow, "test" + i, marker);
markers.push(marker);
}
}
function makeInfoWindowEvent(map, infowindow, contentString, marker) {
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map, marker);
});
}

this is the area where you can add your content of popup
var infowindow = new google.maps.InfoWindow({
content: "Add your popup content here"
});
and this is for showing your popup
marker.addListener('click', function() {
infowindow.open(map, marker);
});
Below code shows how its work and use.
features.forEach(function(feature) {
var infowindow = new google.maps.InfoWindow({
content: "Add your popup content here"
});
var marker = new google.maps.Marker({
position: new google.maps.LatLng(lat,long),
icon: "image.png",
/*icon: icons[feature.type].icon,*/
title: "Title for marker",
map: map
});
marker.addListener('click', function() {
infowindow.open(map, marker);
});
});

var infowindow = new google.maps.InfoWindow();
var marker = new google.maps.Marker({
position: myLatLng,
....
content: point[4]
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(this.content);
infowindow.open(map, this);
});
Code inside loop. This worked for me perfectly.

That's because the variable i is not used in the loop but when the marker is clicked -- and then i is equal to the last index + 1... The addListener is asynchronous, not synchronous.
Remove infowindow.setContent('test: ' + i + ''); and replace content: " " with content: 'test: ' + i. This should fix your problem.

infowindow closing and var (google maps api v3)

I have problem with closing infowindow when new is open in google maps api v.3.
var infowindow;
function addMarker(id, location) {
contentString = 'some content';
var marker = new google.maps.Marker({
position: location,
map: map
});
var infowindow = new google.maps.InfoWindow({
content: contentString,
maxWidth: 200
});
google.maps.event.addListener(marker, 'click', function() {
if (infowindow) infowindow.close();
infowindow.open(map, marker);
});
markersArray[id] = marker;
}
The problem is that in above code the old infowindow is not close when new one is clicked unless I delete var from the line var infowindow = new google.maps.InfoWindow({
But then all the infowindows have the same content...
Any help?
Thanks.

Use a global variable to contain a pointer to the last opened marker, and when opening a new one, close the previous one. Like this
//var infowindow; // <-- removed; should not be global
var openedInfoWindow = null; // <-- added this here; make sure it's global
function addMarker(id, location) {
contentString = 'some content';
var marker = new google.maps.Marker({
position: location,
map: map
});
var infowindow = new google.maps.InfoWindow({
content: contentString,
maxWidth: 200
});
google.maps.event.addListener(marker, 'click', function() {
if (openedInfoWindow != null) openedInfoWindow.close(); // <-- changed this
infowindow.open(map, marker);
// added next 4 lines
openedInfoWindow = infowindow;
google.maps.event.addListener(infowindow, 'closeclick', function() {
openedInfoWindow = null;
});
});
markersArray[id] = marker;
}
