Calling javascript from perl with Ajax

Hi,
I have a web page with a Google Map on it. The google map shows the user their current location (using HTML5).
There is a drop down on the page with some town names.
When a user selects a town name from the drop down, the event fires off a javascript function using AJAX, which then calls a perl script. The perl script queries a database and gets coords for the town the user selected in the drop down.
The next thing I *want* to do is place a marker on the map that shows the person where the town they selected is.
The part that has got me stumped is once I am in the perl script through the Ajax call, how do I pass the coords back to a javascript to put the marker on the map?

The only solution I can think of is to redraw the entire page in the perlscript, passing the coords to a javascript function using something like this
<body onload=placeMarker(lat1,lat2)>
I was hoping there was some other way I could do it that would be more elegant that would allow me to just pass back coords to the javascript without having to redraw the whole page.

Anyone?

Thanks,
Nacht

I believe that all the code you need is on this page: https://developers.google.com/maps/articles/phpsqlsearch_v3  That version returns the info in XML format.   On this page https://developers.google.com/maps/documentation/javascript/basics , they have a link to a lot of code sample for different displays.
