[Inkscape-user] When to use onclick(evt) and when to use onclick(event)?

25 Apr 2017


      Hi all,
Within a <svg> element in my HTML body, I can use onclick(evt), as
exemplified below:
============================================================
<svg width="500px" viewBox="0 15 80 30">
  <circle id=circ1 r="6" cx="10" cy="30" onclick="top.doit(evt)" />
</svg>
============================================================
I can change the "evt" to "event" and it still works,  but if I change
it to anything else, for example "e", it fails. Is evt some kind of
reserved word within SVG?
By the way, if an item in HTML itself (like a paragraph) has an
onclick, you need to remove the "top." and only "event" will work.
I have the rudiments of a clickable map using SVG, CSS and Javascript,
and am starting to build it into something useful.
Thanks,
