Hi Karl,
The use of innerHTML is fairly common. I actually asked Klaus Hartl the
same thing awhile back and here's his reply:
"according to the IE documentation, the innerHTML property is read-only
for the following elements: col, colgroup, frameset, html, style, table,
tbody, tfoot, title and tr. And I think also select (but I'm not sure
anymore, because I cannot find anything in the docs).
Most relevant here are table and select elements I guess. Populating a
selectbox by simply changing innerHTML ( $('select').html('<option> ...
</option>') ) doesn't work. For tables a fix is already in jQuery. "
I think alot of people like using innerHTML because of the convenience
and according to this blog entry by Rob Gonda, speed:
