Google Maps integration into website
I want to make a web application that will get 2 location and their postalcode and show the result on google map. For example, I select 2 cities or a country and show the road map with a 开发者_运维问答colored line according to my points.
Best place to look is the Google Maps API V3 Documentation - I recommend V3 as they don't support V2 anymore
Main documentation: http://code.google.com/apis/maps/documentation/javascript/
Samples: http://code.google.com/apis/maps/documentation/javascript/examples/index.html
Simple directions sample: http://code.google.com/apis/maps/documentation/javascript/examples/directions-simple.html
Basically you need to have the two co-ordinates, although you can use street addresses, and pass that to the API and it goes off to google gets the results and then plots it. Easy as pie!
Save this code as location.html
