Adding an Infobox to GoogleMaps? - javascript

I'm trying to add an infobox to a number of pins on a Google map.
I've got the infobox to work previous - JSfiddle.
But i've now altered the code to include a dropdown menu. I've tried to add the infoboxes again but it doesn't work and i don't understand why it doesn't. JSfiddle.
I've copied and pasted the code for the infoboxes, checked that the variable names still match up, and that the code is in the same order.
The following code is where the marker is added to the map and i'm trying to add an infobox. The function addMarker is sat within my initialisation function. And var infowindow is sat beneath the initialisation function.
function addMarker(feature) {
var marker = new google.maps.Marker({
position: feature.position,
icon: feature.icon,
map: map,
size: 20,
title: name,
draggable: false,
//animation: google.maps.Animation.DROP
});
google.maps.event.addListener(marker, 'click', (function (marker) {return function () {
var Infocontent = feature.desc;
infowindow.setContent(Infocontent);
infowindow.open(map, marker); //'mouseover'
}
})(marker));
}
var infowindow = new google.maps.InfoWindow();
May someone please tell me where i've gone wrong?

I just updated your code by creating a new fiddle and now it is showing infowindow. I just moved your infowindow code within listener definintion.
Please check
google.maps.event.addListener(marker, 'click', (function (marker) {return function () {
console.log('called');
var Infocontent = feature.desc;
infowindow = new google.maps.InfoWindow();
infowindow.setContent(Infocontent);
infowindow.open(map, marker); //'mouseover'
}
})(marker));

Google maps - reuse single infoWindow for multiple markers

I have multiple markers and currently when more than one infoWindow is clicked, the other already-opened infoWindows stay open, cluttering the map. I would prefer it if I could simply reuse a single infoWindow, move it and update it's content. This is what I am attempting to do below:
var info = new SnazzyInfoWindow ();
/*
* Loop through each item in the 'features' array, including info windows, and display the marker
*/
features.forEach(function (feature) {
var marker = new google.maps.Marker({
position: feature.position,
icon: icons[feature.type].icon,
map: map
});
var infoContent = feature.contentImage + feature.content;
marker.addListener('click', function() {
infoCallback(infoContent, marker);
});
});
function infoCallback(infoContent, marker) {
return function() {
info.close();
info.setContent(infoContent)
info.open(map, marker);
};
};
However I am receiving the error Cannot read property 'placement' of undefined and can't seem to figure out what's wrong here.
Note that I am using the "Snazzy Info Window" plugin, but I think the same would apply to the stock infoWindow.
Yes. Inside the onClick function, when marker.addListener('click' is being executed, you don't have feature/marker. The variables are not what they were when the foreach was executed.
One trick I mostly use, is to make an array of the marker objects. Inside the onClick you search for the 'this' marker inside the array.
Something like this:
var markers = []; // store the markers in this array
features.forEach(function (feature) {
var marker = new google.maps.Marker({
position: feature.position,
icon: icons[feature.type].icon,
map: map
});
markers.push(marker);
marker.addListener('click', function() {
// first find out which marker was clicked on
var index = markers.indexOf(this); // this represents the marker that was clicked on
// index should be the same index as the index for features.
var feature = features[index];
var marker = markers[index];
var infoContent = feature.contentImage + feature.content;
// now we can call infoCallback.
infoCallback(infoContent, marker);
});
});

ionic, how to display correct infowindow on google maps?

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);
});

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;}

trigger google maps marker click

I have a google map set up to find the user's current location, and center the map at that closest marker to their location. The markers, when clicked, open up an infobox (note this is a little different than an infoWindow - http://google-maps-utility-library-v3.googlecode.com/svn/trunk/infobox/docs/examples.html). What I want to do, however, is automatically open up the nearest marker without the user actually clicking. Here's the code to trigger a marker opening:
//loop through all locations to add a marker:
addMarker = function(loc) {
var markerLoc = new google.maps.LatLng(loc.Lat, loc.Long);
var marker = new google.maps.Marker({
map: map,
position: markerLoc
});
google.maps.event.addListener(marker, "mousedown", function() {
var infoOpts = {
content: loc.markerText,
boxStyle: { background: "none transparent", width: "180px"},
pixelOffset: new google.maps.Size(-90, 0),
closeBoxMargin: "5px"
};
var ib = new InfoBox(infoOpts);
ib.open(map, marker);
});
markers.push(marker);
};
So somehow I have to trigger the mouseDown function of the appropriate marker, but it has to be done in a function outside of this one. I will have a reference to the appropriate marker in the array (markers[closestmarker]).
I see that this question has been sitting for quite awhile, but, just in case, this answer may be helpful:
trigger google maps marker click
The code would look like this:
var marker = new google.maps.Marker({});
new google.maps.event.trigger( marker, 'click' );
I found I needed to attach a click event to the marker like so
var marker = new google.maps.Marker({});
marker.addListener('click', function() {
infowindow.open(map, marker);
});
new google.maps.event.trigger( marker, 'click' );

infowindows on pushpins not closing on google maps

Im using google maps api v3. im adding markers by caling this function:
function createMarker(posn, title, html) {
var marker = new google.maps.Marker ({position:posn, title: title, draggable: false});
var infowindow = new google.maps.InfoWindow({content: html});
google.maps.event.addListener(marker, "click", function() {
infowindow.open(map,marker);
});
return marker;
}
it works okay, the only problem is when i click a pushpin the window opens, but when i click another pushpin the first pushpins infowindow window does not close both infowindows are visible.
Don't know if you solved this, but the way I did it was:
function createMarker(posn, title, html) {
var marker = new google.maps.Marker ({position:posn, title: title, draggable: false});
google.maps.event.addListener(marker, "click", function() {
infowindow.open(map,marker);
});
infowindow = new google.maps.InfoWindow({content: html});
return marker;
}
This works, and the windows close when another pin is clicked, but the "X" close button doesn't work...
You need to keep track of your info windows in an array and close them programmaticaly when a click event fires so using your example
//define a global array
infoWindows = new Array();
//..do your stuff
function createMarker(posn, title, html) {
var marker = new google.maps.Marker ({position:posn, title: title, draggable: false});
var infowindow = new google.maps.InfoWindow({content: html});
//add this infowindow to an array
infoWindows.push(infowindow);
google.maps.event.addListener(marker, "click", function() {
//go through the array and close all open info windows
for (i=0;i<infoWindows.length;i++) {
infoWindows[i].setMap(null);
}
//open current info window
infowindow.open(map,marker);
});
return marker;
}
