Ajax + Google maps

Ajax + Google maps


Hi guys,
we are developing an aplication and we are using ajax and java
script.What we want to do is to get a point at the map and calculate
the distance from this point to others points that we have at a xml
file. Until now we could read the xml file. Our problem is that we
could not build the map at the frame and we could not get this
distance.
to calculate this distance we are using a function from google maps
called "gdir.load" and "getDistance().meters"
regards!
