strange; i missed that when i put it together; my bad, it was late.
here is a revision that works.
<html>
<head>
<script type="text/javascript">
window.onload = function() {
var someLink = document.getElementById('someLink');
someLink.href += "&anotherVar=8";
alert(document.getElementById('someLink').href);
}
</script>
</head>
<body>
<a id="someLink" href=" http://somesite.com?a=5";>
click here
</a>
</body>
</html>
the problem was the local variable was being assigned the value of the
attribute, not the reference
to the tag in the dom. i have now set it to be a reference to the variable
in the dom.
