The source file `foo/bar.mdwn` or `foo/bar.html` generates the
page `foo/bar/index.html`, but the links to the page appear
as "`foo/bar/`". This is fine (and recommended) for pages
served by an http server, but it doesn't work when browsing
the pages directly using `file:` URL. The latter might be
desirable when testing pages before upload, or if you want to
read pages when off-line without access to a web server.
Here is a JavaScript "`onload`" script which fixes the URLs
if the `local.protocol` isn't `http` or `https`:
function fixLinks() {
var scheme = location.protocol;
if (scheme=="http:" || scheme=="https:") return;
var links = document.getElementsByTagName("a");
for (var i = links.length; --i >= 0; ) {
var link = links[i];
var href = link.href;
var hlen = href.length;
if (hlen > 0 && link.protocol==scheme && href.charAt(hlen-1) == "/")
links[i].href = href + "index.html";
}
}
This can be placed in `page.tmpl`:
<html>
<head>
<script language="JavaScript">
function fixLinks() {
...
}
</script>
</head>
<body onload="javascript:fixLinks();">
...
</html>
This script has not been extensively tested.
