Googlemaps v3 directions - javascript

I'm trying to make a new Google maps for my website which always used v2. Everything is going fine till last detail...after asking directions I know there "should" be a line drawn on the map which visualizes the directions. That blue line is not showing on my map and tried many things but no luck...any suggestions are highly appreciated!
For anyone who would like to see the script in action: http://www.pruikenboer.nl/googlev3.html
Thanks in advance!

You create the map twice, at first the map where you want to draw the route, then onload a new map, which overwrites the first one.
Solution: create only 1 map-object

Add animation to an interactive map (javascript)

Hello i got a problem for add animation to an interactive map.
I add a map in wordpress with the plugin responsive vector map... at the moment it works, but i need to add animation to the interactive map, in special, regions of the map that appear separated and then come together forming the map.
I've been searching, but I haven't found any solution.
Thank you for your attention and regards
You can use Google Maps API and code it by hand if you are good at coding :)

Adding an interactive map to my website

I'm relatively new coder and am currently putting together a website as part of my University work. I'd really appreciate it someone could give me advice on how I would go about adding an interactive map that uses JavaScript to show my location.
Thanks!

Google maps, just copy paste and edit the latlong to your desired position.
And here is one example getting position from browser and marks it on the map:

So you're trying to lay an image on to google maps, in a specific location? If so, I think this should be able to help you:

Google Maps markers ontop of each other

So I have a probably not so unique scenario. The simplest way to explain it is a google map with all 50 US states, each state will have two markers. The markers are both driven by the same lat/long value. The problem Im having is that the markers are rendering ontop of one another. I somehow need to have them render next to one another or offset so that I can see both. The problem is how do I get it to not overlap into another state.
I saw some really neat "spider" functionality where it renders one marker and then if you click on it the others fan out, but the website was in another language.
I am going to try and use the following library.
https://github.com/jawj/OverlappingMarkerSpiderfier
The problem with the above implementation is that I am using a combination of KML and google maps client-side. I dont see a way to implement that for the kml markers
The Overlapping Marker Spiderfier project on GitHub will probably accomplish what you need.
Otherwise you can play around with the Marker's icon property. The icon can accept a Symbol which has and anchor that can be shifted from the default location (0,0).
Symbol documentation: https://developers.google.com/maps/documentation/javascript/reference#Symbol

GoogleMaps: How to add marker without zooming out.

I have a list of people that I need to map. Some of them have geocoded addresses and others don't. So, I map the ones that I have, and then I geocode the ones that I don't have geocodes for, and I add them to the map one at a time. (side note: the google geocoder api has a limiter that allows you geocode 10 addresses the first second that you hit it, and then 1 per second every second after that). So, I as I am geocoding these addresses, I am creating Markers and adding them to the map. The problem here is that I can't effectively interact with the map from the UI while the other addresses are being geocoded, because each time I call marker.setMap(mymap) it re-zooms out to fit all markers. So, I can't interact with the map until they are all mapped. Is there any way to add a marker to the map without re-zooming out?
Geocoding and creating a marker doesn't automatically shift the center of the map. If you copied from the Maps API sample code, you may see a line like
map.setCenter(results[0].geometry.location);
That's causing the results to the center of the map. Comment out that line and see if there's still a problem.If you don't see setCenter, then look for a line with fitBounds() and comment that out. If you're still having trouble, post a live version of your code, or put it up on jsFiddle or something so we can debug it.
