Dynamically determine current field element?

[M Wells]

Hi All,

Is it possible to dynamically determine the current field element in a
form?

I ask because I have a 'tab' button on a form, and when a user clicks
on it I need to be able to shift the focus to the next field, and also
if the current field is the last field on the form, essentially to do
nothing.

Conceptually, I guess I'm trying to do something like:

function clicktab(){

variable = current.field.e lement.number;
if (variable < n) {
variable++;
document.forms[0].element[variable].focus;
}
}

In the above function, "n" would be the total number of fields in the
form.

I'd very much appreciate any assistance anyone can give!

Much warmth,

Murray

If you are willing to do some initializing, you can attach
onfocus-handlers to every field, that write their tabIndex to a global
variable. Then, on click of your tab button, you can increment the
global variable and set focus on that element.

Know how to proceed?

Hiya,

What I'm wondering is if there's any way of retrieving the element
number of the field.

So, a way of knowing that document.forms[0].elements[5] currently has
the focus, as opposed to document.forms[0].elements[6] etc.

Much warmth,

Murray

Without any action before? wishing "document.curre ntElement"?
I doubt it, I couldn't find anything pointing in that direction when I
searched. Can you put window.getSelec tion to use?
