ionic, how to display correct infowindow on google maps? - javascript

I have several markers in a google map using their javascript API and I want to display an info window on top of the tapped marker, however when you tap in one of the markers in opens the info window in the last marker created not in the corresponding marker, sample code:
for(var i = 0; i < points; i++) {
var randomLatLong = new google.maps.LatLng(position.coords.latitude + getRandomArbitrary(-radius, radius), position.coords.longitude + getRandomArbitrary(-radius, radius));
var marker = new google.maps.Marker({
map: $scope.map,
animation: google.maps.Animation.DROP,
position: randomLatLong,
});
var infoWindow = new google.maps.InfoWindow({
content: "Here is something to see!"
});
marker.addListener('click', function () {
infoWindow.open($scope.map, marker);
});
}
here is a codepen:
http://codepen.io/ospfranco/pen/yOPpey
just tap on one of the markers and te info will open on other marker
Anyone knows how to solve this?

Just change 'marker' to 'this' in your listener.
marker.addListener('click', function () {
infoWindow.open($scope.map, this);
});

JavaScript: Get Selected Google Marker

I'm having a google map where google markers are put up. The placement of markers works well. But if I click a marker, the adress should open up in an infowindow. The adress, longtitude and latitude are loaded from model.js into the variable myLocations.
EDIT: Currently a click on any marker returns the adress of the last object in myLocations. But I would like to get the myLocations.adress of the one who was clicked.
var markerspots;
var spot;
var j;
for (j = 0; j < myLocations.length; j++){
spot = {
lat: parseFloat(myLocations[j].lati),
lng: parseFloat(myLocations[j].long)
};
contentString = myLocations[j].adress;
markerspots = new google.maps.Marker({
position: spot,
map: map,
icon: markerspot,
content: contentString,
id: j
});
var infowindow = new google.maps.InfoWindow();
google.maps.event.addListener(markerspots, "click", (function(marker) {
return function(evt) {
infowindow.setContent(contentString);
infowindow.open(map, markerspots);
}
})(markerspots));
}
I have found lots of solutions, but I don't understand any of those. So how can I make the content of the clicked marker show up in an infowindow?
Thanks
Well you are accessing your contentString, which is set to the last one you created in your for loop.
What you really want is the content property of the marker you clicked on, which is stored in this.
So
google.maps.event.addListener(markerspots, 'click', function() {
console.log(this.content);
});
should do the trick.

Google Maps with multiple markers in Bootstrap Modal

I'm trying to display a Google map in a Bootstrap modal with multiple markers. I have found several posts where people were having problems displaying the map on the modal with just one marker, but none with multiple markers. This is what I currently have, but my map is just showing up gray.
var locations = [...]
var complexMap = new google.maps.Map(document.getElementById('complexes-modal-map-canvas'), {
mapTypeId: google.maps.MapTypeId.ROADMAP
});
//create empty LatLngBounds object
var bounds = new google.maps.LatLngBounds();
var infowindow = new google.maps.InfoWindow();
for (i = 0; i < locations.length; i++) {
var marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
icon: locations[i][3],
map: complexMap
});
//extend the bounds to include each marker's position
bounds.extend(marker.position);
google.maps.event.addListener(marker, 'click', (function (marker, i) {
return function () {
infowindow.setContent(locations[i][0]);
infowindow.open(complexMap, marker);
}
})(marker, i));
}
$("#complexes-modal-map-canvas").on("shown.bs.modal", function () {
var currentCenter = complexMap.getCenter();
google.maps.event.trigger(complexMap, "resize");
complexMap.setCenter(currentCenter);
complexMap.fitBounds(bounds);
});
There are 2 things I had to do to make this work. The first thing was an obvious mistake - I was selecting the incorrect element on the "shown.bs.modal" method. I needed to select my Bootstrap modal, not the Google Map. The second thing was to call the "fitBounds" method before calling the "resize" event and setting the center.
$("#complexes-modal").on("shown.bs.modal", function () {
complexMap.fitBounds(bounds);
var currentCenter = complexMap.getCenter();
google.maps.event.trigger(complexMap, "resize");
complexMap.setCenter(currentCenter);
});

How to add click event listener to infoWindow

i'm developing my first web application using Google Maps Javascript API v3 (with markers clustering libraries). Here is part of my code:
var markersReady = [];
for (var i = 0; i < markers.length; i++) {
var data = markers[i];
var myLatlng = new google.maps.LatLng(data.lat, data.lng);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: data.title,
icon : 'images/marker.png',
});
(function (marker, data) {
google.maps.event.addListener(marker, "click", function (e) {
infoWindow.setContent("<div id='info'><p id='title'>" + data.title + "</p><p>" + data.desc + "</p></div>");
infoWindow.open(map, marker);
});
})(marker, data);
markersReady.push(marker);
}
As you can see i add an event listener to every marker to make them clickable. When users click on one of them, it shows the infoWindow. Now how to add an event listener to the infoWindow as well? I'm using Bootstrap and i want to show a modal when user click on infoWindow popup. In addition, how to pass parameters to modal so every modal shows info according to the clicked marker?

Google Map looped markers wont close previous infowindow [duplicate]

This question already has answers here:
Google Maps JS API v3 - Simple Multiple Marker Example
(15 answers)
Closed 9 years ago.
Using a loop to show markers on Google Maps, I am finding that previous windows wont close even though I have a listener
Here is my code (set to limit number to 50 deliberately) that displays a marker if a user has location info set
function loadGmodule() {
var map = new google.maps.Map(
document.getElementById('gmashup'), {
center: new google.maps.LatLng(20, 0),
zoom: 1,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
for (var i=0;i<50;i++) {
u = users[i];
if (u.lat) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(u.lat, u.lang),
map: map
});
infoContent[i] = '<table ><tr><td><img src=\"'+u.avatar+'\" width=\"60\" height=\"75\"></td>';
infoContent[i] = infoContent[i] + '<td><b>'+u.firstname+' '+u.middlename+' '+u.lastname+'</b><br />'+u.designation + '<br />'+u.company+'<br />'+u.city+'</td>';
infoContent[i] = infoContent[i] + '</tr></table>';
var infoWindow = new google.maps.InfoWindow();
infoWindow.setContent(infoContent[i]);
addInfoWindowOnEvent(marker, infoWindow, map, 'click');
}
}
}
and the function / listener
function addInfoWindowOnEvent(marker, infoWindow, map, event) {
google.maps.event.addListener(marker, event, function () {
infoWindow.close();
infoWindow.open(map, marker);
});
}
Can anyone advise the best location to put the infoWindow.close() so that previous windows will shut when another pin is clicked.
Thanks in advance for any assistance
Even though the edited indicated a duplicate, it was not to be found in the supplied link.. HOWEVER (even though I think this is a hack, but it will do) there was an answer here which worked
Google Maps API v3 (one infowindow open at a time)
I changed my function to
function addInfoWindowOnEvent(marker, infoWindow, map, event) {
google.maps.event.addListener(marker, event, function () {
if($('.gm-style-iw').length) {
$('.gm-style-iw').parent().remove();
}
infoWindow.open(map,marker);
});
}
and now only one window stays open
For each marker you are creating new infowindow. If you want to close previous infowindow and have only one opened then it is enough to create only one infowindow. It should be global:
var infoContent = [];
var infoWindow;
function loadGmodule() {
var map = new google.maps.Map(
...
infoWindow = new google.maps.InfoWindow();
//for (var i = 0; i < 50; i++) {
for (var i = 0; i < users.length; i++) {
...
and then provide specific content to event listener:
...
infoContent[i] = infoContent[i] + '</tr></table>';
//infoWindow = new google.maps.InfoWindow();
//infoWindow.setContent(infoContent[i]);
addInfoWindowOnEvent(marker, infoContent[i], map, 'click');
}
}
}
function addInfoWindowOnEvent(marker, infoContent, map, event) {
google.maps.event.addListener(marker, event, function () {
infoWindow.close();
infoWindow.setContent(infoContent)
infoWindow.open(map, marker);
});
}

Open info window on load Google Map

I'm wondering if it's possible to open one of the infoWindow objects that are attached to each marker in the code below on page load and not just by clicking on them? As it is now, the user has to click on one of the markers to open an info window.
I tested to create a "stand alone" info window object and that opened fine onload, but it didn't close when I clicked on some of the other markers, because the onClick function was attached to the markers that only could close the info windows attached to that object. Correct med if I'm wrong?
Would this be possible and can I "call" an object by the number or what options do I have? Tips are preciated!
Or if there is possible, that I have tried to open an separate info window onload and be able to close that if I open one of the other info windows!?
var map = null;
var infowindow = new google.maps.InfoWindow();
var iconBase = 'images/mapNumbers/number';
//var zoomLevel = 11;
//var mapPositionLat = 55.678939;
//var mapPositionLng = 12.568359;
function initialize() {
var markerPos = new google.maps.LatLng(55.674196574861895, 12.583808898925781);
var myOptions = {
zoom: 11,
//center: new google.maps.LatLng(55.678939, 12.568359),
center: markerPos,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
google.maps.event.addListener(map, 'click', function () {
infowindow.close();
});
google.maps.event.addListener(map, 'zoom_changed', function () {
infowindow.close();
});
google.maps.event.addDomListener(window, 'resize', function() {
map.setCenter(markerPos);
map.setZoom(zoomLevel);
//var center = map.getCenter();
});
// Add markers to the map
var point;
point = new google.maps.LatLng(55.667093,12.581255); createMarker(point, "<div class='infoWindow'>1</div>");
point = new google.maps.LatLng(55.660794,12.58972); createMarker(point, "<div class='infoWindow'>2</div>");
point = new google.maps.LatLng(55.660491,12.587087); createMarker(point, "<div class='infoWindow'>3</div>");
}
// Create markers
function createMarker(latlng, html, name, number) {
var marker = new google.maps.Marker({
position: latlng,
map: map,
title: name,
icon: iconBase + number + '.png'
});
google.maps.event.addListener(marker, 'click', function () {
infowindow.setContent(html);
infowindow.open(map, marker);
//map.setCenter(marker.getPosition());
map.setCenter(55.678939, 12.568359);
});
}
google.maps.event.addDomListener(window, 'load', initialize);
In order to display InfoWindow when the map loads, make the call to
infowindow.open(map, marker);
outside of the marker listener.
Below is demonstrated createMarker function, where parameter displayInfoWindow defines whether to display InfoWindow when the map loads:
// Create marker
function createMarker(map,markerPos, markerTitle,infoWindowContent,displayInfoWindow) {
var marker = new google.maps.Marker({
position: markerPos,
map: map,
title: markerTitle,
});
var infowindow = new google.maps.InfoWindow({
content: infoWindowContent
});
if(displayInfoWindow) {
infowindow.open(map, marker);
}
google.maps.event.addListener(marker, 'click', function () {
infowindow.open(map, marker);
});
}
Example: http://jsbin.com/lusuquwu/1/
It is possible. One possible solution is to save markers to an array and then trigger click event on of one of them using google.maps.event.trigger(). For example:
...
var zoomLevel = 11; // uncommented due to error message
var markers = [];
function initialize() {
...
point = new google.maps.LatLng(55.660491,12.587087); createMarker(point, "<div class='infoWindow'>3</div>");
google.maps.event.trigger(markers[1], 'click');
}
function createMarker(latlng, html, name, number) {
var marker = new google.maps.Marker({
position: latlng,
map: map,
title: name,
//icon: iconBase + number + '.png'
icon: iconBase
});
// added to collect markers
markers.push(marker);
google.maps.event.addListener(marker, 'click', function () {
console.log('click event listener');
infowindow.setContent(html);
infowindow.open(map, marker);
//map.setCenter(marker.getPosition());
// corrected due to error
map.setCenter(new google.maps.LatLng(55.678939, 12.568359));
});
}
I combined info from this and another site to come up with the below solution as most solutions are for multi-marker maps.
Just a few lines is all you actually need.
// Start with your map
var map = new google.maps.Map(...);
// Now define the info window using HTML. You can insert images etc.
var info = new google.maps.InfoWindow({content: 'YOUR HTML HERE'});
// Now define the marker position on the map
var marker = new google.maps.Marker({map: map, position:{lat: 'YOUR LATITUDE',lng: 'YOUR LONGITUDE'}});
Now we have the variables, just hide the marker, show the info window and set the map zoom and center.
// Set the map zoom
map.setZoom('YOUR ZOOM LEVEL [1 - 20]');
// Set the map center
map.setCenter({lat: 'YOUR LATITUDE',lng: 'YOUR LONGITUDE'});
// Hide the marker that we created
marker.setVisible(false);
// Open the info window with the HTML on the marker position
info.open(map, marker);
For the content, you can create layers and insert images and text as you need. Just make sure you include the full URL to images in your html.
I also recommend adding this to your CSS to hide the close button, which effectively makes this a permanent, info window.
.gm-style-iw + div {display: none;}
