Executing function when <link> navigation element is used

Spartanicus · Nov 16, 2006

I'd like to execute a function when a <link rel="next" href="foo.htm">
type element is used. Although the "onclick" handler is allowed on the
element, presumably because the functionality of the element is made
available through a browser provided navbar the function doesn't execute
when using the element.

Anyone know if this is possible?

Never done anything with a navbar but you might try setting the
href="javascript:functionName()"

onload = function() {
var L = document.getElementsByTagName('link');
var ok = false;
for(var i=0; i<L.length; i++)
if(L.href && L.href.indexOf('foo.htm')>0 &&
L.rel && L.rel=='next') ok=true;
if(ok) alert('right link');
}

I need to preserve the href attribute value. I use JS to rewrite that
value, but I don't want to make the feature JS dependant.

onload = function() {
var L = document.getElementsByTagName('link');
var ok = false;
for(var i=0; i<L.length; i++)
if(L.href && L.href.indexOf('foo.htm')>0 &&
L.rel && L.rel=='next') ok=true;
if(ok) alert('right link');
}

By "used" I meant "clicked", not present in the code.

How do you expect to click something not present ?

<html>
<script type="text/javascript">
onload = function() {
var L = document.getElementsByTagName('A');
for(var i=0; i<L.length; i++)
if(L.href && L.href.indexOf('foo.htm')>0 &&
L.rel && L.rel=='next')
L.onclick = function() {
alert('Gasp! I am discovered');
return false;}
}
</script>
<a href="#">test 1</a>
<a rel="next" href="foo.htm">foo</a>
<a href="foo2.htm">test 1</a>
</html>

That is the question I was asking. I'm not sure what phrase to use, not
"used", not "clicked", "activated" would probably have been better.

I am now experimenting with Randy's suggestion after I realised that I
could use <link rel="next" href="foo.htm"> in the HTML and then rewrite
the href value to "javascript:functionName()" with JS.
