Hi,

I have the following code for a google map event:

@map.event\_init(@map,:click,“function(overlay,point)  
{  
if (overlay)  
{  
map.removeOverlay(overlay);  
document.getElementById(“latitude”).value=null;  
document.getElementById(“longitude”).value=null;  
}  
else  
{  
map.addOverlay(new GMarker(point));  
document.getElementById(“latitude”).value=point.y;  
document.getElementById(“longitude”).value=point.x;  
}  
}”)

As you can see, the action is written in JS.  
How can I call a ruby action from that code, so I can handle events  
properly?

Thanks,
