I need to send geo coördinates from a mysql database to a google maps  
javascript.

There´s no problem to get them into rails…But how can i send them to  
javascript ?

I know javascript is client side so i think it´s impossible to include  
ruby variables…

Suggestions ?

Thanks

What I always do is this: have Rails put the data in a hidden HTML  
element with a known ID. Then the JavaScript can read the contents of  
that element.
