Is it possible to dynamically the URL of a feed that has been instantiated in the header of a page via JavaScript?
For example, is it possible to update the URL of the rss feed in the following snippet:
<html>
<head>
<link rel="alternate" title="Feed" href="/rss.feed" type="application/rss+xml">
</head>
<body>
...
</body>
</html>
I guess you could do this:
<script type="text/javascript">
linkCol = document.getElementsByTagName("link");
for(i = 0; i < linkCol.length; i++) {
if(linkCol[i].title == "Feed") {
linkCol[i].href = "NEW HREF";
}
}
</script>
Try the following:
document.getElementsByTagName("link")[0].href = "http://example.com/";
If it’s not the first and only link element, you have to look for it first, e. g.:
var linkElems = document.getElementsByTagName("link");
for (var i in linkElems) {
if (linkElems[i].href === "/rss.feed") {
linkElems[i].href = "http://example.com/";
break;
}
}
I'm pretty sure that most browsers will not see the change. But I'd love to be proven wrong.
