Hey all, i am working with google maps and a function in the Elabel  
that i am using to put data on a map.

In the docs for the Elabel, there is a function  
label.setContents(html) where html is what will go inside the  
Elable.

it looks like this:

var weather\_table\_one = new ELabel(new GLatLng(35.5,-102), \<%=  
@weather\_table\_html %\>, “style1”);  
map.addOverlay(weather\_table\_one);

what i need to do is update the data in the map every time the map  
moves ( with a listener ) and every 20 seconds or so.  
So i thought i would use a PeriodicalExecuter where the function is  
setContents(html) but i don’t know how to fetch that html

any tips would be greatly appreciated.
