I have a new/create method that only has one field, and I’d rather use a  
js prompt() to get the data instead of a form.

The trigger for this is not a link, it’s a span. Using “onclick” in the  
span, how can I call a prompt(), return the single param to the  
contoller “create” method, and then call the controller “list” method to  
update the page?

I am thinking it is actually impossible to pass a client side javascript  
variable into the server side rails without hiding a form somewhere…

Well you can make an Ajax request, and pass the value of the  
javascript variable in a query parameter in the url.
