[thelist] Proper way to append to a links onclick handler

Hey all,
I have an HTML page with a link that pops open a URL in a new window.
The link is as follows:
<a href="url.html" onclick="window.open(this.href, 'windowname',
'width=100;height=100'); return false" target="windowname">link</a>
Nothing special really.
However, for users with javascript enabled, we want to intercept clicks
on links on the page, so we have a window.onload function which does
something like this:
function onloadFunction()
{
if (document.links)
{
for (var i = 0; i < document.links.length; i++)
{
document.links[i].onclick=clickFunction;
}
}
}
Again, nothing to special.
Both seem to work when separated, but when I put them together, the
popup window code at the top doesn't work.
So, I figure that in the onload function I have defined to override the
onclick handler of all links on the page, that I need to append any
onload handler that may have already been defined, but unfortunately, I
can't seem to get it to work:
document.links[i].onclick= clickFunction +
document.links[i].onclick;
The above doesn't do what I would hope it to do (namely perform the
clickFunction() and then and onclick handler that had been previously
defined by an individual link.
Is there something obvious that I am missing?
Thanks,
Roger
