Description Anne 2009-01-05 16:28:33 UTC
Both Presto and WebKit currently handle a self-closing flag on a <script> element start tag in a special way.

In WebKit it always pops the element of the stack.

In Presto it pops the element of the stack if a src attribute with a non-empty value is also present.

Gecko and Trident do not handle the flag in a special way.

WebKit style parsing breaks at least this page: http://www.google.com/codesearch/p?hl=en#fYNO89zotsk/sahana-phase1/damagereg/web/Login.jsp&q=%3Cscript[^%3E]*/%3E

It is unfortunately near impossible for Opera and WebKit to change behavior drastically due to deployed Dashboard and Opera widgets. (Introducing differences between Web page and widget rendering would be theoretically possible (and admittedly WebKit has done this for <canvas>), but is not desirable.)

I would like to do more research into what pages would break and which would work better, but unfortunately Philips' tool cannot be used.
Comment 1 Ian 'Hixie' Hickson 2009-01-05 22:51:12 UTC
I'm not changing the spec just because certain UAs reuse the same codebase for non-Web environments, that doesn't make sense. Especially since, as you point out, it causes problems.
Comment 2 Anne 2009-01-06 15:00:50 UTC
http://www.madaen.com/ breaks in Firefox (and probably IE?).

I haven't found a site yet that breaks in Opera due to this issue and some sites using code like this would work "better":

  <script src='http://www.google-analytics.com/urchin.js' type='text/javascript'/>
  <script type='text/javascript'>
    _uacct = 'UA-1723287-3';
    urchinTracker();
  </script>

E.g. http://discotec08.ifi.uio.no/FMOODS08/HomePage and http://yskin.net/
