24 * Transclude: Include an external web page within the body of a wiki page.
28 * src=http://www.internet-technology.de/fourwins_de.htm
31 * @author Geoffrey T. Dairiki
33 * @see http://www.cs.tut.fi/~jkorpela/html/iframe.html
36 * Will only work if the browser supports <iframe>s (which is a recent,
39 * The auto-vertical resize javascript code only works if the transcluded
40 * page comes from the PhpWiki server. Otherwise (due to "tainting"
41 * security checks in JavaScript) I can't figure out how to deduce the
42 * height of the transcluded page via JavaScript... :-/
44 * Sometimes the auto-vertical resize code doesn't seem to make the iframe
45 * quite big enough --- the scroll bars remain. Not sure why.
