[Zope] Dynamically generating JavaScript

Mon Feb 14 09:53:33 EST 2005

When I've had to include dynamic javascript I write a python method that
prints the whole script block and then call that from a tal:block.

<tal:block tal:replace="structure python: here.myscript_js()" />

myscript_js would look like this

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

return printed
