doing direct ajax calls using js can be instructional one time, but
not very practical to do many times...
I strongly recommend giving jquery a try. if you know a little
javascript, you can already give jquery a try
there are lots of jquery tutorials, find one of your taste ;)
but one thing i'd recommend is to first try to echo a list of
name,lat,lng with jquery ajax call (get, for example, can be seen as a
simple way to "include" an external php page) and update it. (no
gmaps, just regular php echo'ing)
once it works, then you make it update the markers.
you'll probably make an marker array, then put the markers on the map.
so once you get new data from the jquery ajax call, you'll clean the
current marker array and show the new one.
jquery is intuitive to use, this experience will be good. have fun!
