How do I use Javascript in my Coldfusion page?

I have a coldfusion page and I am very newbie in coldfusion. What I need to do is to insert the alert in between to see what is the time. In php I could close the php tags and enter the javascript tag and alert out the value. How would I do that in coldfusion? I have this

<cfset right_now=Now()> 
        <cfscript>
    alert(#right_now#);
    </cfscript>

But its not working. thanks

Always remember the coldfusion begins and ends before anything else is executed: html, javaScript, sql, etc., so the javascript is getting an already formed code, which is CF instead of being hard coded.

You don't need to even use cfscript for this specific need. You could, for instance, do this:

<script type="text/javascript">
     var currtime = new Date();
     alert(currtime);
</script>

... Also a point to remember, you can't directly output HTML from within a <cfscript> tag. You can however get around this by calling a function from within a <cfscript> tag that can output the data for you.

<cfscript> is a Coldfusion tag for using the Coldfusion scripting language (aka CFScript). If you want to use Javascript, open a <script> tag like you would normally in HTML. You'll probably want to make sure it's inside a <cfoutput> tag if you want to use Coldfusion values within your javascript.

<cfset right_now = Now()>

<cfoutput>
<script type="text/javascript">
  alert('#right_now#'); // don't forget you need to put quotes around strings in JS
</script>
</cfoutput>
