change colour on infoWnd close google maps api - javascript

I want to my pin to change color when I click on it in google maps.
I have the below code, the color changes but I want it to revert back to the original when the infowindow is closed. see fiddle
Where am I going wrong here?
<div id="map_canvas"></div>
var mylatlongs = [
{"rank":1,"name":"name 1","lat":"-25.901820984476252","lng":"135"},
{"rank":2,"name":"name 2","lat":"-25.901820984476252","lng":"135.05"},
{"rank":3,"name":"name 3","lat":"-25.901820984476252","lng":"135.025"}
];
var infowindow = null;
jQuery(function() {
var StartLatLng = new google.maps.LatLng(mylatlongs[0]['lat'], mylatlongs[0]['lng']);
var mapOptions = {
center: StartLatLng,
streetViewControl: false,
panControl: false,
maxZoom:17,
zoom : 13,
zoomControl:true,
zoomControlOptions: {
style:google.maps.ZoomControlStyle.SMALL
}
};
var map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
var infowindow = new google.maps.InfoWindow({
content: ''
});
jQuery.each( mylatlongs, function(i, m) {
var StartLatLng = new google.maps.LatLng(-25.901820984476252, 134.00135040279997);
var marker = new google.maps.Marker({
position: new google.maps.LatLng(m.lat, m.lng),
bounds: true,
id : 'mk_' + m.rank,
letter : m.index,
map: map,
title: m.name
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.close();
infowindow.setContent(contentString);
infowindow.open(map,marker);
marker.setIcon('https://www.google.com/mapfiles/marker_green.png');
});
var contentString = '<div id="content">'+
'<div id="siteNotice">'+
'</div>'+
'<h1 id="firstHeading" class="firstHeading">'+ m.name + '</h1>'+
'<div id="bodyContent">'+ (m.rank) +
'</div>'+
'</div>';
});
});
#map_canvas {
float: left;
height: 565px;
width: 100%;
}
#content {
min-width: 320px;
}

You don't track which marker has infowindow open. One possible solution is to add global variable which will contain information about marker with opened infowindow:
var infowindow = null;
var markerRed;
And change icon to red color when marker is clicked:
google.maps.event.addListener(marker, 'click', function() {
if (markerRed) {
markerRed.setIcon('https://www.google.com/mapfiles/marker.png');
}
infowindow.close();
infowindow.setContent(contentString);
infowindow.open(map,marker);
marker.setIcon('https://www.google.com/mapfiles/marker_green.png');
markerRed = marker;
});
Update: icon change on close of infowindow:
var infowindow = new google.maps.InfoWindow({
content: ''
});
google.maps.event.addListener(infowindow, 'closeclick', function() {
if (markerRed) {
markerRed.setIcon('https://www.google.com/mapfiles/marker.png');
}
});

Change google map marker icon when clicking button inside infowindow

I have multiple markers on the map that I have imported from JSON. Inside the marker infowindow I have a button and when clicking on that, I want to change the marker image. Please check my code below. Marker list and Infowindow is working fine. I just want to do some actions on the button that is inside infowindow.
var workerlist;
var jobprice;
var price;
var map;
var list;
var position;
var image;
var image1;
var marker;
function myMap() {
var mapProp= {
center:new google.maps.LatLng(30.7333,76.7794),
zoom:10,
disableDefaultUI: true
};
map = new google.maps.Map(document.getElementById("map"),mapProp);
image = 'images/blue_marker1.png';
image1 = 'images/pink_marker1.png';
console.log(workerlist);
for (var i = 0; i < workerlist.length; i++) {
list = workerlist[i];
price = jobprice;
position = new google.maps.LatLng(list.latitude,list.longitude);
addMarker(map,list,price,position,marker);
}
}
function addMarker(map,list,price,position,marker){
marker = new google.maps.Marker({
position: position,
title: list.name,
map: map,
icon: image
});
var contentString = '<div class="mapBox">'+
'<div class="content"> <h3>'+ list.name +
'</h3>'+
'<h6>(2.1 miles from the job venue)</h6>' +
'<div class="rating"></div>'+
'<p>Total cost to hire:</p>'+
'<p>Rate: $' + price.Price + ' per hour</p>'+
'<p>Total Cost: $'+ price.total_amount +'</p>'+
'</div><button id="shortList" class="btn btn-shortlist" onclick="shortList()">Shortlist for the JOb</button>'+
'</div>';
marker.addListener('click', function() {
if (typeof infowindow != 'undefined') infowindow.close();
infowindow = new google.maps.InfoWindow({
content: contentString,
})
infowindow.open(map,marker)
$("#shortList").click(function(){
image = 'images/pink_marker1.png';
});
});
}
function shortList(){
// alert('clicked');
// infowindow.close();
//marker.setIcon(image1);
}
Before you can access the <button id="shortList"> in the DOM with JQuery, it needs to be added to the DOM. That happens asynchronously when the InfoWindow content is rendered, the domready event on the InfoWindow fires when it is available.
google.maps.event.addListener(infowindow, 'domready', function() {
$("#shortList").click(function() {
// code here to change the icon
});
});
related question: How to detect button click in googlemaps infowindow
If you want the icon of the marker to change, you need to call .setIcon on the marker:
marker.addListener('click', function() {
if (typeof infowindow != 'undefined') infowindow.close();
infowindow = new google.maps.InfoWindow({
content: contentString,
})
infowindow.open(map, marker)
var that = this; // save reference to marker to change its icon
google.maps.event.addListener(infowindow, 'domready', function() {
$("#shortList").click(function() {
image = 'http://maps.google.com/mapfiles/ms/micons/orange.png';
that.setIcon(image);
});
});
});

I'm working on a view of the ASP.NET, using mvc. I using google maps with different markers. Each of those markers have their own infowindows that have 3 buttons each. By clicking a specific button I want the marker to change color. How can I do that?
I have already tried using document.getElementById and using the addEventListner. I also tried to program the button by using the onclick function.
var locations = [
["Recusado", "13/02/2019", 38.776816, -9.441833, 335, "foto.jpg", ],
["Aceite", "15/08/2019",38.817562, -8.941728, 36, "foto.jpg"],
["Em avaliação", "20/07/2019",38.487978, -9.004425, 90,"foto.jpg"],
["Concluído", "01/07/2019",37.045804, -8.898041, 12, "foto.jpg"]
];
var infowindow = new google.maps.InfoWindow({});
function setMarkers(map) {
for (var i = 0; i < locations.length; i++) {
var fire = locations[i];
var marker ;
var contentString = '<div id="content">' +
'<div id="siteNotice">' +
'</div>' +
'<div id="bodyContent">' +
'<p><b>Avaliação da Ocorrência:</b></p>' +
'<p>Fotografias:' + fire[5] + '</p>' +
'<p>Avaliação:' + fire[0] + '</p>' +
'<p>Data:' + fire[1] + '</p></br>' +
'<button id="aceite">Aceite</button>' +
'<button>Recusado</button>' +
'<button> Em avaliação</button>' +
'<button> Concluído</button>' +
'</div>';
var infoWindow = new google.maps.InfoWindow({ content: contentString });
marker = new google.maps.Marker({
position: { lat: fire[2], lng: fire[3] },
map: map,
info: contentString,
icon: 'http://maps.google.com/mapfiles/ms/icons/blue-dot.png'
});
google.maps.event.addListener(marker, 'click', function () {
infoWindow.setContent(this.info);
infoWindow.open(map, this);
});
}
}
The buttons are represented in the variable contentString, and when I click the button with the id "Aceite", I want to change the color of the marker to green.
Attempt to change the marker to green:
<button id="aceite" onclick="state(marker)">Aceite</button>
function state(marker){
marker.setIcon('google.com/mapfiles/marker_green.png');
}
Simplest would be to add the click listener function when you open the InfoWindow (when you know what marker it is associated with).
Add the click listener to the button when the domready event of the InfoWindow fires (and it has been added to the DOM):
google.maps.event.addListener(infoWindow, 'domready', function() {
google.maps.event.addDomListener(document.getElementById("aceite"), 'click', function(e) {
marker.setIcon('http://maps.google.com/mapfiles/marker_green.png');
})
});
Use function closure on the marker in the marker click listener (this references the marker in the click event listener function, but not in the InfoWindow domready event listener, save it so you can use it there):
google.maps.event.addListener(marker, 'click', function() {
var marker = this;
infoWindow.setContent(this.info);
google.maps.event.addListener(infoWindow, 'domready', function() {
google.maps.event.addDomListener(document.getElementById("aceite"), 'click', function(e) {
marker.setIcon('http://maps.google.com/mapfiles/marker_green.png');
})
});
infoWindow.open(map, this);
});

Google Map API - infowindow in foreach loop

Hello I'm retrieving data from SqlServerCe so I created foreach loop to create markers - that works it creates multiple markers but now I wanted to add to each of these marker an infowindow. But now whenever I click on marker the infowindow pops-up on the lastly created marker.
<script>
function initialize() {
var mapProp = {
center:new google.maps.LatLng(51.508742,-0.120850),
zoom:5,
mapTypeId:google.maps.MapTypeId.ROADMAP
};
var map=new google.maps.Map(document.getElementById("googleMap")
, mapProp);
$(function () {
#foreach (var row in data)
{
<text>
var marker = new google.maps.Marker({ position: new google.maps.LatLng(#row.GeoLat, #row.GeoLong),
map: map });
marker.info = new google.maps.InfoWindow({
content: "test"
});
google.maps.event.addListener(marker, 'click', function() {
marker.info.open(map, marker);
});
</text>
}
});
}
google.maps.event.addDomListener(window, 'load', initialize);
May someone help me with adding infowindow to each created markers?
Thank you for your responding and your time.
This is how I load from SqlServerCe
var db = Database.Open("StarterSite");
var data = db.Query("SELECT DescriptionService,GeoLong,GeoLat FROM services");
var array = new []{data} ;
You can use the following, written in javascript
var infoWindowContent = [];
for(var index=0; index< places.length; index++){
infoWindowContent[index] = getInfoWindowDetails(places[index]);
var location = new google.maps.LatLng(places[index].latitude,places[index].longitude);
bounds.extend(location);
marker = new google.maps.Marker({
position : location,
map : map,
title : places[index].title
});
google.maps.event.addListener(marker, 'click', (function(marker,index){
return function(){
infoWindow.setContent(infoWindowContent[index]);
infoWindow.open(map, marker);
map.setCenter(marker.getPosition());
map.setZoom(15);
}
})(marker,index));
}
function getInfoWindowDetails(location){
var contentString = '<div id="content" style="width:270px;height:100px">' +
'<h3 id="firstHeading" class="firstHeading">' + location.title + '</h3>'+
'<div id="bodyContent">'+
'<div style="float:left;width:100%">'+ location.address + '</div>'+
'</div>'+
'</div>';
return contentString;
}
I added an array infoWindowContent then added the information to the array. You can use the same logic

Googlemaps: center location on sidebar link

I currently have a googlemap canvas with a sidebar with links that when clicked, take the user to the latlong location with a marker and infowindow. When the map is loaded, this is centered but when they click the links the map doesnt pan to the center with the marker in the middle.
I have tried added a map.setCenter within my marker function but this makes the map and markers disappear with no errors in my console. Can anyone guide me to a snippet of code or tutorial which could help? Here is my example code:
<script type="text/javascript">
var side_bar_html = "";
var gmarkers = [];
var map = null;
function initialize() {
var myOptions = {
zoom: 12,
center: new google.maps.LatLng(46.18363372751015,12.4530029296875),
mapTypeControl: true,
mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU},
navigationControl: false,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"),myOptions);
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
var point = new google.maps.LatLng(46.18363372751015,12.4530029296875);
var marker = createMarker(point,"example 1","location 1 info")
var point = new google.maps.LatLng(39.31517545076218, 35.25238037109375);
var marker = createMarker(point,"example 2","location 2 info")
document.getElementById("marker_list").innerHTML = side_bar_html;
}
var infowindow = new google.maps.InfoWindow({
size: new google.maps.Size(150,50),
});
function myclick(i) {
google.maps.event.trigger(gmarkers[i], "click");
}
function createMarker(latlng, name, html) {
var contentString = html;
var marker = new google.maps.Marker({
position:latlng,
map: map
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map,marker);
});
gmarkers.push(marker);
side_bar_html += '<a href="javascript:myclick(' + (gmarkers.length-1) + ')">' + name + '<\/a><br>';
}
</script>
If you want the map to center on the marker when it is clicked, you need to write code to do that. By default it pans so the InfoWindow is visible. Change this:
function myclick(i) {
google.maps.event.trigger(gmarkers[i], "click");
}
To something like:
function myclick(i) {
map.setCenter(gmarkers[i].getPosition());
google.maps.event.trigger(gmarkers[i], "click");
}

Google Maps gets weird when i'm open infoWindow's (UTF-8)

I'm using Google maps for a new project, but my map gets weird when I open an infoWindow.
See the picture below:
Does anyone recognize this problem?
Here is my code for the map initialization:
$(document).ready(function(){
function initialize() {
var myLatlng = new google.maps.LatLng(59.398554, 5.486206);
var mapOptions = {
draggable: true,
zoomControl: true,
mapTypeControlOptions: {
mapTypeIds: [google.maps.MapTypeId.ROADMAP, google.maps.MapTypeId.HYBRID]
}, // here´s the array of controls
disableDefaultUI: true, // a way to quickly hide all controls
scrollwheel: false,
zoom: 13,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
var contentString = '<div id="content">'+
'<div id="siteNotice">'+
'</div>'+
'<h2 id="firstHeading" class="firstHeading">FjørSilkeBris</h2>'+
'<div id="bodyContent">'+
'<p>Førland, 5570 Aksdal</p>'+
'<p>481 49 246 (Mobil)</p>'+
'<p>Facebook: FjørSilkeBris på facebook.</p>'+
'</div>'+
'</div>';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"Fjørsilkebris"
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
};
window.onload = function () {
initialize();
}
});
I had the same problem.
The problem is, some CSS on your page is most likely setting the img element's max-width property to 100%. This breaks the infowindow's css on the map.
What you can do is override the img max-width of your map's canvas div example:
#divMap img { max-width: none; }
This worked for me
