[ale] JavaScript and server address

Mon Jun 4 22:49:21 EDT 2007

I know even less about Java than I do about JavaScript, and I don't
know a lot about JavaScript. I do know that one is not a derivative of
the other.

If you want to get the current URL in the address bar, you just need
to take a look at `window.location`. With a little bit of RegEx magic,
you should be able to get what you need. Here is an example:

<html>
<head>
<script type="text/javascript">
function tmp() { address=window.location; alert(address); }
</script>
</head>
<body>
<input type="button" onclick="tmp();" value="clickme">
</body>
</html>

"All governments suffer a recurring problem: Power attracts
pathological personalities. It is not that power corrupts but that it
is magnetic to the corruptible. Such people have a tendency to become
drunk on violence, a condition to which they are quickly addicted."
