Thanks Peter -- I can't believe I totally missed that. Both examples work
now. It still doesn't work if I put it directly in a hyperlink though
(unless I remove the new lines):
<a
href="javascript:window.open('data:text/html,%3Chtml%3E%0D%0A%3Chead%3E%3Ctitle%3Etest%3C%2Ftitle%3E%3C%2Fhead%3E%0D%0A%3Cbody%3E%3Ch1%3E42%3C%2Fh1%3E%3C%2Fbody%3E%0D%0A%3C%2Fhtml%3E');">test</a>
BTW, I'm just experimenting - I just discovered data URLs and am seeing what
kinds of things I can do with them.
