The point above is that the designer does not know how to code that I agree 100% with. So any JS implies that either the programmers are doing the design or they extract the GUI from the design wasting time. In fact even templates can be too high barrier to ask a designer to use them, but at least with templates the design->working site conversion is simpler and any competent programmer should be able to learn the templates.
I also find that asking the designers to put keywords in the site mockup and use that as ad-hock templates could work rather well.
