Generic Form Validation.
tboland@gmail.com
http://www.techtoolblog.com
License: Free To Use, If Modified/Added
please send updated source to tboland@gmail.com

To Validate a Form Element Add the Custom Attribute:
validate="VALIDATEHOW"
 
Your Current Options Are:
"not_empty"
"integer"
"number" - decimal allowed
"email"
"phone" - includes international phone numbers

Multiple Validation uses the following syntax:
validate="not_empty|integer"

To Add a Message Add the Custom Attribute:
msg="Name is a required field" 

By Default the Messages are shown next to the form element.
To Show Alert Boxes add a Custom Attribute in the form tag (show_alert):
<form action="mypage.aspx" show_alert="1? onSubmit="return Validate(this);">

Examples:
<html>
<head>
<script language="JavaScript" src="gfv.js" type="text/javascript"></script>
</head>
<body>
<form action="mypage.php" show_alert="1? onSubmit="return Validate(this);">
First Name <input type="Text" name="FirstName" maxlength="25? validate="not_empty" msg="First Name is Required" /><br/>
Email <input type="text" name="Email" maxlength="25? validate="email" msg="Email is Required" /><br/>
<input type="submit" value="Go">
</form></body></html>

ADVANCED USERS:
Add Your Own Function Calls to the validate attribute.
It Must return true or false
example:
<input type="text" name="Age" validate="ValidateAge" />
