How do I capture a link click event

I need to capture the href value when a user click on any links on the page. Can I do it as a global event capture, everytime someone clicks a link.

this is a simple example of how to get the link value. But if u want to capture it into the database or whatsoever you need server side scripts.

<a href="abc.htm" onClick="javascript: alert(this.href);">dsd</a>


Commented:
You can do it for all href's too. Use the following script:

<script>
function clickhref(obj)
{
   alert(obj.href);
}


function doc_onload()
{
  for(i=0;i<document.links.length;i++)
    document.links[i].onclick=new function(){clickhref(this);}
}
</script>

Commented:
If some of the links are already using the onclick handler, then the above won't work. Try this approach:

1) add left click handler to the document
2) in the handler, if the event source is an <a> tag, get its href property, then throw the event again or exam the href value, ie if "javascript:" do an "eval()" or just do "document.location.href = href".

Hi CJ

I called the doc_onload() from the onload event and it keeps executing the function clickhref for each href and displays an alert box with object undefined.

The solution you have given me is what I want if I can get it to work.

There is already an onclick event on one link, so I take it that is why CJ's code it not working. Can you elaborate on your possible workaround.
