Dynamically generating JavaScript

14 Feb 2005

      I have a page template within with I would like to embed some 
dynamically generated JavaScript. Say the following sample snippet:

<script>
var1 = 1;
var2 = 2;
var3 = 3;
</script>

The 'obvious' approach I came up with is the follow zpt code:

<script>
<tal:block tal:repeat="i python:range(1,4,1)">
var<span tal:replace="i"/> = <span tal:replace="i"/>
</tal:block>
</script>

However, this code doesn't even compile correctly, with the error:

TAL.HTMLTALParser.NestingError: Open tag <script> does not match close 
tag </tal:block>

If instead I replace the <script> and </script> tags with things like 
<html> and </html>, the code compiles. Obviously, I am missing a very 
important point about the way zpt works, but I can't find what. Maybe it 
is not suitable for this kind of task and I shall use DTML or 
PythonScript instead?

Any hint would be appreciated.
