No. Protoype is not even needed for this -- that is, no javascript_include_tag is necessary -- because history.go is a basic JavaScript feature, not a Prototype library function. > > After much digging and searching I discovered this: > > <a href="Javascript:history.go(-1)">Back</a> > > I think it automatically turns on JS. No. Nothing "automatically turns on JS". For obvious reasons, there is no JavaScript code that would turn on JavaScript interpretation in the user's browser. Check your browser options and make sure you have JavaScript turned on -- that's the only way to do it. Also, using javascript: pseudo-URLs in the href field is generally a bad idea (and note the lowercase j!). Using onclick as in my original example is much better. > I am using NB 6.5 for Ruby/Rails.
