Hi all –

Newbie to JavaScript.

I’m working through tutorials in
[I]JavaScript for the World Wide Web, Fifth Edition (Visual QuickStart Guide)”
Tom Negrino[/I]

I can’t figure out what is wrong with this script
When I run it in Firefox 2 I receive a blank screen
When I run it in IE 7, I receive:

[QUOTE]

This page requires JavaScript.

[/QUOTE]

As expected.

Could yo please point to what I might be doing wrong?
I’ve checked it several times and I don’t see it
Full code below

Thanks

@JMRKERJun 05.2008 — Several errors.

1. need to finish each statement with a ';'

2. do not capitalize the 'if' command

3. missing <h1> start anchor

See:
[code=php]
<?xml version="1.0" encoding="UTF-8"?>
<DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>My Javascript Page</title>
<script language="Javascript" type="text/javascript">
<!-- Hide script from old browsers
ans = prompt("Are you sure you want to do that?","");
if (ans != '') { alert("You said "+ans); }
else { alert("You refused to answer"); }
// End hiding script from old browsers -->
