Javascript Focus Command

[amerar@iwc.net]

Hi All,

I have a form with multiple text boxes. I want to have one validation
routine, and, if something fails, I'd like to put the focus in that
text box.

So, how can I 'remember' which text box I came from, so I know which to
send the focus back to? They all have different names, but I do not
want to code something like this for every text box:

function datevalidation( entered, alertbox) {;
with (entered) {;
if (value==\"?\");
{if (alertbox!=\"\" ) {alert(alertbox );} return false;};
else {return true;};
};
};

if (emailvalidatio n(Email1,\"Ille gal E-mail\")==false) {Email1.focus() ;
return false;};

Any suggestions?

Thanks.

<URL:http://www.merlyn.demo n.co.uk/js-valid.htm#VFF>, but start reading
at the beginning of the page.

Also, ==false is silly; see ! in
<URL:http://www.merlyn.demo n.co.uk/js-logic.htm#OO>, ditto.

<URL:http://www.merlyn.demo n.co.uk/js-other.htm#Dbg> : Code should be
indented, by a couple of spaces per level, to show the logical
structure.

There's no point is having an else after an if ... return.
