onSubmit and validation issue

This is my first time posting here and I am new to CF. I took and passed a figleaf course on Cold Fusion and have some other programing background.

The issue that I cannot seem to resolve has to do with onSubmit. Here is some very basic code straight out of my Fast Track to CF class...

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns=" http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Insert Artist Form</title>
</head>

<body>

<h2>Insert an Artist</h2>

<cfform name="insArtist">

First Name:
<cfinput type="text" name="FirstName" maxlength="20" required="yes" message="Please input an artist first name." validateat="onserver" /><br/>

Last Name:
<cfinput type="text" name="LastName" maxlength="20" required="yes" message="Please input an artist last name." validateat="onsubmit" /><br/>

<cfinput type="submit" name="Insert" value="Insert Artist" />

</cfform>

</body>
</html>

When I leave the fields blank the onServer message does come up.

If I take out first name and try to verify only Last Name I can click as much as I like on the Submit button but the alert never comes up with the message "Please input an artist last name."

I have set up a system using XP SP3 and the same issue happens on Firefox 3.0.3 or IE 7.

I am using CFEclipse, Apache, and CF8. I have Virtual Hosts set up for my sandbox.

Please let me know if any other information is needed.

Thanks for your help.

Dave

Thanks JR "Bob" Dobbs you pointed me in the right direction.

The issue was how I had set up my virtual directories. Being that I am new to web development I didn't understand how that scripts directory was being accessed. I fixed this issue, with some help from the boss by adding the following to my http.conf file for apache.

# "C:/Program Files/Apache Software Foundation/Apache2.2/cgi-bin" should be changed to whatever your ScriptAliased
# CGI directory exists, if you have that configured.

Your code seems to be valid.

Check these items:
1. Are the supporting javascript files accessible to your browser? They are located in /CFIDE/ and are named /CFIDE/scripts/cfform.js and /CFIDE/scripts/masks.js

2. Does your browser have javascript enabled?

3. Is the browser reporting any javascript exceptions?

Also note that the validateAt="onServer" works by adding a hidden form field that instructs the server on what to validate. It can be easily bypassed by a user so I wouldn't rely on it.

Error Console in Firefox specifies this line as a problem...

if( !_CF_hasValue(_CF_this['LastName'], "TEXT", false ) )

This is code that is generated by CF on the fly though.. All I'm doing is setting onSubmit.

Sounds like the supporting javascript files cannot be found by the browser.

Can you browse to /CFIDE/scripts/cfform.js or /CFIDE/scripts/masks.js?

Both files are available in C:\dev\CFIDE\scripts on my machine. I have a virtual host set up to get into cfadmin

<VirtualHost *:80>
ServerAdmin webmaster@dummy-host2.localhost
DocumentRoot "C:\dev\CFIDE"
ServerName www.cf8.localhost
ErrorLog "logs/dummy-host2.localhost-error.log"
CustomLog "logs/dummy-host2.localhost-access.log" common
</VirtualHost>

The CFIDE folder and cfdocs folder are both in a folder called dev where I am hosting my apache root. I notice, though I don't know if it's important, that WEB-INF is in a wwwroot folder like this C:\ColdFusion8\wwwroot.

Any ideas what I can do to fix this? Thanks for replying JR "Bob" Dobbs!

You need a directory or virtual directory /CFIDE.

I'm not familiar with Apache, but this link may help.

The virtual directory is Dev/CFIDE. Thanks for working this out with me. Maybe it does have to do with pathing but the directory is there.

If you add the attribute scriptSrc="/Dev/CFIDE/scripts" to your cfform tag does the validation work?

Can you browse to /Dev/CFIDE/scripts/cfform.js?

The validation still is not working. Also I can get to the cfform.js does exist in /Dev/CFIDE/scripts/cfform.js.

I am heading home but I will pick up on this in the morning and try looking at the pathing some more.
