Comment (by lukeplant):
My example should have been {{{$("#id_email")}}} of course, which I'm sure
jQuery will optimise into a simple {{{document.getElementById()}}} without
doing any DOM traversal. Or you can do this yourself, without the jQuery
dependence. Either way, I'm sure it can't take 5 sec no matter the size of
the document. If you want designers to be able to do this by just editing
templates, your options are:
* Use the above method of adding event handlers using
{{{document.getElementById()}}} (or some wrapper, like jQuery).
* Don't use Django to render the entire form -- render it field by field
in the template, overriding with custom HTML as necessary.
* Some complex template tag that allows you to add "onchange" handlers to
a form field from within the template. This would likely be very messy,
and not actually designer friendly.
This discussion is straying from the feature request first given in the
bug, of course -- adding event handler attributes in Python code is
already supported by {{{attrs}}}, and won't help your use case. If you
have a more concrete suggestion about how to better support adding event
handlers in the template, it would be best to open another ticket.
