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
<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>
JsStringformat to correctly escape strings! A timestamp has single quotes in itself, which will cause errors. like that.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.
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.
