AFAICT, the spec doesn't cover this case when the parser tries to run script. 39394 1 ian 2010-09-25 19:33:20 +0000 How can the script not be in the document? 39575 2 zcorpan 2010-09-27 12:41:00 +0000 I think something like: <button onclick="s=document.getElementsByTagName('script')[0]; s.parentNode.removeChild(s)">remove</button> <script> // the parser has inserted the script element into the document // server sleeps for a while here and you click on the button alert(1); </script> (or by using setTimeout etc) 39713 3 hsivonen 2010-09-28 11:05:47 +0000 Or simply <div> <script> // detach the div from the document </script> <script> // this script won't be in the document when the parser tries to run it </script> 40091 4 ian 2010-09-30 08:30:24 +0000 Makes sense. 40724 5 ian 2010-10-06 17:37:32 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.
