public class FormHelpTemplate
Template class for adding field help to the FormTemplate. The "help" attribute of the <form> element specifies a javascript template used to generate an event handler for each form element. The "help" attribute on each form element is passed to the javascript template, allowing a (user supplied) javascript function to present field specific help. The help text for each feld may be supplied as a server config file.
"help" feature:
This template may be used to provide field specific help with a little
external javascript "glue". For example, the markup:
<form event=onfocus help="do_help(%)"> ... <input name=foo ... help="help for this input field"> ... </form>will generate:
<form> ... <input ... onfocus='do_help("help for this input field")'> ... </form>This works with the form elements <input> <select>, and <textarea>. The "event" defaults to "onfocus". If
foo.help
is a defined property then it is used as
the help text.
