How to return to form element

[Vance Heredia <Va...@lonelyplanet.com.au>]

I use the Action Errors to validate a form.  

If I do find errors does anyone know how to set the focus to the first
eroneous field present on the form when it returns to it ???

Well I dont know of any easy way to do it

but you could probably make use of the action errors somehow.

maybe create, in your message resurces file, a piece of javascript that
dynamically set the name of the field to be focused on. Then the onload
function would focus on it for you. Sounds a bit complicated but would go
something like this.

-- if form validate --
boolean firstField = true;
if(myField == null)
{
	if(firstField)
	{
		errors.add("javascriptErrors", new ActionError("error.js.field.missing",
fieldName));
		firstField = false;
	}

}

-- in message resources --

error.js.field.missing = <script>focusField = {0}</script>

-- in page --
<script>
var focusFiled = null;
</script>

<body onload="if(focusField != null) document.all[focusField].focus;">

<html:errors property="javascriptErrors"/>



That's if you're making use of the message resources feature.

Just one possible suggestion

Steve
