JavaScript in WP Pages

Hi there
I have looked at other posts for this solution, but cannot find.
Apologies if I missed posted solution.
Am rusty with web-dev, and new to WP, and I want to put a ‘Bookmark us’ link in a clients WP-Page. – similar to the “javascript.internet.com” code at bottom of this post.
I’ve read the “Javascript in Posts” Codex advice, but can’t get it to work.

How do I get a non-template, one-time JavaScript to work in WP?

Thank you

<script language=”JavaScript”>
function bookmark(url,title){
if ((navigator.appName == “Microsoft Internet Explorer”) && (parseInt(navigator.appVersion) >= 4)) {
window.external.AddFavorite(url,title);
} else if (navigator.appName == “Netscape”) {
window.sidebar.addPanel(title,url,””);
} else {
alert(“Press CTRL-D (Netscape) or CTRL-T (Opera) to bookmark”);
}
}
</script>

<form action=”#”>
