Hey everybody,  
I am trying to create a button that, when clicked on, calls a method  
in a controller then changes the image on the button without a page  
load. I was thinking that button\_to\_function might be a good  
contender for this but I don’t yet know how to make it talk to a  
controller, and on success change the image of the button. Can anyone  
help me out with this problem?

Thanks,  
John

If you need to talk to controller, then it will load the page right?  
Just put some helper method and call it in the button\_to\_function. Iam  
not sure.

button\_to\_function ‘Click me’, remote\_function(:url=\>{:action =\>  
‘foo’, :controller =\> ‘bar’}}

remote\_function takes basically the same options as link\_to\_remote and  
generates the javascript for an ajax call. You’ll want to read about  
rjs for the final step of your problem
