Subject: [Edbrowse-dev] script in tree of document.written elements?
Date: Tue, 15 Aug 2017 17:18:41 -0700 (PDT) [thread overview]
Message-ID: <alpine.LRH.2.03.1708151706370.12666@carhart.net> (raw)

I found out something potentially important and good. It is relevant to
test zero, and actually has implications for a lot of other tests.
Consider this mini page, hello.html
<HTML>
<BODY>
<SCRIPT>
document.write('<P>odd</P>');
</script>
</BODY>
</HTML>
Should the inserted <P> have <SCRIPT> in its series of parentNodes as it
descends from document?
Here's my edited edbrowse transcript for this. Asterisks signify my
input.
* b hello.html
79
4
* jdb
* x1 = document.getElementsByTagName("P")
[object Object]
* x2 = x1[0]
[object Object]
* x2.parentNode.nodeName
script
* x2.parentNode.parentNode.nodeName
body
This is relevant to the acidtests because test zero runs removeChild of
the last script. The last script is this:
<script type="text/javascript">document.write('<map name=""><area
href="" shape="rect" coords="2,2,4,4" alt="<\'>"><iframe
src="empty.png">FAIL<\/iframe><iframe
src="empty.txt">FAIL<\/iframe><iframe src="empty.html"
id="selectors"><\/iframe><form action="" name="form"><input
type=HIDDEN><\/form><table><tr><td><p><\/tbody>
<\/table><\/map>');</script>
So it merrily removes all of that stuff inside of document.write.
Subsequent tests try to find those elements and they no longer exist!
If script does not occur in the tree of those iframe, form, etc,
then they will be available later on!
