[Zope] ZPT changing javascript (HOW?) - Easy with DTML

Thu, 3 Oct 2002 14:10:15 -0700

Speaking here as someone who knows XHTML and XML but not ZPT: This probably
won't work. <script> isn't supposed to contain other tags. Go read the FAQ
on the XHTML validator for some idea of how javascript and XHTML just don't
mix well. Consider moving your script into python or dtml.

Also, you shouldn't do this for empty elements:

<sometag/>

You should always place a space in there:

<sometag />

Again, see the XHTML spec, validator, and validator FAQ.
