Legge til marker ved klikk (google maps)

[uranus]

Hei!

 

Har en lang kode jeg bruker med Google Maps her, blant annet søkefunksjon osv. Alt funker veldig bra, men det jeg argher meg over er at jeg ikke ønsker at marker er der før man klikker en gang på kartet. Kan noen hjelpe meg endre dette?

 

Her er koden:

 

 

 

<script type="text/javascript">

var map;
var marker;
var places = [ ];
// geocoder variables and constants

	reasons[G_GEO_UNAVAILABLE_ADDRESS] = "Unavailable Address:  The geocode for the given address cannot be returned due to legal or contractual reasons.";
	reasons[G_GEO_BAD_KEY] = "Bad Key: The API key is either invalid or does not match the domain for which it was given";
	reasons[G_GEO_TOO_MANY_QUERIES] = "Too Many Queries: The daily geocoding quota for this site has been exceeded.";

Oj, det var da litt v en kode smørje Har du lyst til å dele webside, vil se hvordan dette ser ut

 

Har du sett på eksemplene google selv har gitt ut for API`et?

De har eksempler på de fleste funksjonene. Brukte de flittig da jeg lagde adressebase her på jobben i sommer.

 

eksempel for å hente muesklikk fra kartet og legge til en marker der du klikket: http://code.google.com/apis/maps/documenta...nt-removal.html
