Google Maps Open In Selected City
Question
I have This Map I am working on and it opens at San Francisco. I would like to change this to open at a specified town, country of my choice. (ie London, England or Javea, Spain) The location changes on every page of my site and the "Town & Country" are inserted in the page from a database.
Example: {$listing_city} = Town {$listing_country} = Country
The search box at the top is not needed as I want to show the local restaurants, bars, doctors in that area. However, the search box can stay I just want the map to open in the respective town.
I am new hear and wondered if anyone can help.
Thanks in advance

You have to know latitude of towns you want. Than on every page you need to change this lines in initialize() function from
var myLatlng = new google.maps.LatLng(37.783259, -122.402708);
to
var myLatlng = new google.maps.LatLng(changeTHIS, andTHIS);
here is example for London
var myLatlng = new google.maps.LatLng(51.507222, -0.1275);
