I have a requirement to allow a user to enter a postcode on a webpage and then show that postcode on a Google map along with a number of markers around that postcode showing the location of depots local to that postcode.
I have a database holding a list of depot's but only want to show the depots on the map that are local to the postcode entered, within say 50 miles or so.
I'm using ASPX pages and I can access the database etc.
What I'm looking for is some examples of this sort of functionality using Javascript if possible.
