Is there a way to store the value of a js variable in a ruby variable?  
The reason I ask is because, for example, when a google maps api  
returns the result of let’s say the location on the map, it returns it  
in a js variable. I need to get the value from that variable to be  
stored in a ruby variable. Is there a way in which I can do that?  
Thanks.

make an http request to your app (either an ajax request or a more  
traditional form submission)

Thanks for the idea. I did something like this, but the page keeps  
reloading over and over:
