This one has me stumped, and I'm hoping a second set of eyes will be able to point out the problem. I realize that my abstraction library adds a lot of additional complexity, but I was thinking that someone else may have seen something similar in their implementation. I've also tried to boil this down to as simple and targeted a case as possible.
The problem is that markers created and added to the map via the Google Maps API and set as draggable cannot be dragged. This used to work just fine, but a change I made somewhere in the library broke this functionality. To reproduce, go to http://www.nps.gov/npmap/support/library/examples/map-defaults.html?api=google and then paste the following code in the browser web development console:
var marker = new google.maps.Marker({
position: NPMap.Map.Google.map.getCenter(),
draggable: true,
map: NPMap.Map.Google.map
});
The marker should be draggable, but it is not.
A few notes:
Markers are still clickable, and it seems like all marker events (mouseover, etc.) are working properly
Lines and polygons added to the map as editable work fine
I have played around with the z-index of the map div and some of the other elements, but this doesn't seem to be causing the problem
I am loading the current release version of the Google Maps API, v3.11. I have tested with the frozen version, 3.10, and the experimental version, v3.12, but the problem persists no matter which version is loaded.
Any help is greatly appreciated!
UPDATE: Strange. Markers added with draggable: true don't appear to be clickable. But if a marker is added without specifying draggable: true, it does seem to be clickable. It seems like this is probably related.
UPDATE 2: A follow up to my first update: Events are not working on markers that are created with draggable: true and added to the map. You can run the following code after creating the marker to test this out:
google.maps.event.addListener(marker, 'click', function(e) {
console.log(e);
});
Figured it out. I was doing something like this to hack around some of the default Google Map controls:
var els = document.getElementsByClassName('gmnoprint');
for (var i = 0; i < els.length; i++) {
els[i].style.display = 'none';
}
This hasn't affected draggable markers in the past, but Google must have made a change in the Maps API and started adding the gmnoprint class to draggable markers. Oh well, that's what I get for going outside of the documented API.
I am developing a custom imagemap type map without geo referencing i.e. latlng of my map do not relate to acutal latlng of that place. Now i have also created custom streetview panoramas of certain buildings and places in that map.
The issue is am not able to integrate those custom streetview panoramas with my custom imagemap.
Following is the link to see whats going on:
http://cdi.astateweb.org/virtual_tour/
First Approach:
There are two markers on the map right now. When you click on them a small infobubble pops up. Now when you click on the virtual tour link a dialog comes up. I want to load the custom streetview panorama in that dialog. I tried several things but to no avail. I am trying to reuse the same dialog for both markers. I tried initializing the panorama in jquery ui dialog open function. It worked for the first one but when you close the dialog and open it again it fails with some cbk error from google apis.
SECOND APPROACH:
I tried to use the default streetview pegman such that when the pegman is dropped on a certain building or place which has a panorama the streetview comes up just like in normal google maps. This didn't work either.
Can somebody point me to the right direction. Any help will be highly appreciated.
Thanks
Ok, try like this:
Change at line 41
from
'Virtual Tour'
to
'Virtual Tour'
Change at line 96
$("#dialog").dialog({
autoOpen: false,
width: 650,
open: function() {
console.log($("#" + virtualTour.currentPano));
$("#" + virtualTour.currentPano).appendTo("#dialog").css("display", "block");
},
close: function() {
$("#" + virtualTour.currentPano).appendTo("body").css("display", "none");
}
});
And the below code to add into "createMarker" function.
//After this line.
virtualTour.hotspotArray.push(marker);
//Add this code.
setTimeout(function(){
document.getElementById(pano).style.display = "none";
}, 100);
I have a Google Map Version 3 that I can't quite get working as I want. When the map opens there are several markers on the page and clicking or hovering on the marker opens a little InfoBox with the name of the hotel. Clicking on another marker closes the first InfoBox and opens a new one on the new marker. The problem comes with closing the last InfoBox.
If I allow the closeBox in the options, the closeBox (little cross in a square) gets left on the screen when the rest of the InfoBox is closed. This only happens when the InfoBox closes because another one has been opened. As I can't find a solution to this, I intended to do away with the closeBox and let users click a blank area of map to get rid of the final InfoBox. However, at the moment, that doesn't work either.
The problem page can be seen at http://www.littlehotels-testdomain.co.uk/spain/abadia.php (click on "See a location map for this hotel" just to the right of the photo).
The bit of code which should make this work is:
google.maps.event.addListener(hotelmarker, 'mouseover', function() {
var ib = new InfoBox(ibOptions);
boxText.innerHTML = hotelname;
ib.open(map, hotelmarker);
});
google.maps.event.addListener(map, 'click', function() {
ib.close(map, hotelmarker);
});
Is there something in the second event listener that I am missing?
You need to make your ib (infoBox reference) global. Put it outside your Listener functions.
Andy's 47th rule of JavaScript programming: never use a global variable to accomplish something you can do with a single line using jQuery:
$(".infoBox").hide();
As of Google Maps API v3.6, maps now include "points of interest", which are gray markers embedded into a map. When the user clicks on this icon, an InfoWindow appears with information about that business (or park, hospital, etc.)
These can be turned off by setting the Styling. (See "Style Array Example")
https://code.google.com/apis/maps/documentation/javascript/styling.html
Once they are turned off, the icons, names, and shaded regions (for parks and hospitals) go away.
Before Google Maps API v3.6, there were no icons; only the names and regions.
The question: is there a way to remove the "click icon to open info window" behavior of these points of interest? I still want to keep the icons, names, and regions; only want to remove the click behavior.
Alternate question: is there a way to download/save the JavaScript of the v3.5 of Google Maps API to store on my server? At present, v3.5 is working fine for what I need. In February, Google will no longer provide v3.5 of the code and will instead provide only v3.6, v3.7, v3.8.
Retiring of minor versions of Google Maps API v3, and using the "frozen" version of an API:
https://code.google.com/apis/maps/documentation/javascript/basics.html#Versioning
Things I've tried and considered: Adding an event listener when the map is clicked does not work, because the embedded markers are clicked instead of the map. Adding "clickable: false" as a property was a shot in the dark, with no result. Setting "visiblility: off" removes it all, leaving the map with less content. Setting "visibility: simplified" removes the name of the location, though the onclick behavior is still present. Putting an invisible DIV overlaying the map might work, though it would remove the ability to pan/zoom/drag the map without increasing complexity.
Setting a style so that featureType: poi, elementType: labels, visibility: off will result in showing the pink/gray/green regions for hospitals/cemeteries/parks, without the marker or name. It returns more color to the map.
I'm not sure if this is still relevant to you, but Google did, indeed, solve the issue on April, 2016, all you need to do is clickableIcons to false in MapOptions
This issue has been logged with google at:

I'm not sure this is not a violation of the Google Maps TOS, it's a bit hacky, and doesn't work on IE < 9, but you can listen on dom event,
to detect the creation of the window, using Mutation Observer
Here is a plunkr to demonstrate : http://plnkr.co/edit/pGep9OZFligLhRtHlhgk
You can check in the console, an event is fired (actually twice) when you click on a POI, and the window is hidden
By referencing this URL (https://stackoverflow.com/a/24234818/6160436), I somehow managed to hide the Info windows of POI and call the click event listener of map when the user clicks on the POI.
But I'm not sure whether this violates TOS or not, so use at your own risk.
//keep a reference to the original setPosition-function
var fx = google.maps.InfoWindow.prototype.setPosition;
//override the built-in setPosition-method
google.maps.InfoWindow.prototype.setPosition = function () {
//this property isn't documented, but as it seems
//it's only defined for InfoWindows opened on POI's
if (this.logAsInternal) {
if (this.getPosition()) {
console.log(this.getPosition());
google.maps.event.trigger(map, 'click', {latLng: this.getPosition()});
}
else{
google.maps.event.addListenerOnce(this, 'map_changed',function () {
console.log(this.getPosition());
google.maps.event.trigger(map, 'click', {latLng: this.getPosition()});
// var map = this.getMap();
// //the infoWindow will be opened, usually after a click on a POI
// if (map) {
//trigger the click
var removeInfoWindow = null;
removeInfoWindow = setInterval(function(){
if ($('.gm-style-iw').parent().length) {
$('.gm-style-iw').parent().hide();
clearInterval(removeInfoWindow);
};
},1);
// }
});
};
}
//call the original setPosition-method
fx.apply(this, arguments);
};
google.maps.event.addListener(map,'click',function(e){
alert('clicked #'+e.latLng.toString())
console.log('ok');
});
A couple of things to be aware of:
1)
If your map is high traffic, you may find yourself in violation of the Google Maps TOS. You're supposed to use an official version. If it's your own blog or something else low traffic, nobody will notice or care.
2)
This is only conjecture on my part, but I noticed these POI's myself and got annoyed by them. I am pretty sure these are paid-for "inline ads", so to speak. Some gas stations and diner chains have them, so you will soon see Google maps being spammed with these POI markers. If they allow those to be turned off in the API, it kind of goes against the business interests of those who paid for the POI icon... so I highly doubt that you will be able to remove them.
If you do find a way,please please DO POST the solution! Thanks.
In google maps api v3, I think you can no longer get all the markers on the map object. I need to hide the very last marker from the DirectionsService result. I used to be able to do this in v2:
_gdir.getMarker(_gdir.getNumRoutes()).hide();
I have routes that start and end in the same place, and I need to hide the very last marker so that it does not overlay my original origin maker.
thanks.
If you can settle with hiding all of them then the DirectionsRendererOptions has an option to suppress markers.
https://developers.google.com/maps/documentation/javascript/reference#DirectionsRendererOptions
You hide/remove a marker using the setMap() method with null as the argument:
marker.setMap(null);
Check google docs Remove Marker. Note that the above method does not delete the marker. It simply hide/removes the marker from the map. If you want to show it again just use:
marker.setMap(map);
