Difficult form problem - updating a text box for search

[David]

Hi,

I am trying to achieve the following:

1/ To have a standard form in an asp web page which has various
check boxes and radio buttons.
As a user selects a form item it updates a text box, of which the
contents are submitted to a search page. I know I could just send the
form element data to a search page, but in this app, the user is
creating a product code and need to see the complete code before it is
search on.

Is there a way to add/delete text from a text box as form elements are
selected / un-selected

_____________

2/ Also, what is the best way to hide / unhide form elements when
others are selected ?

Thanks in advance
David

There is no "best" way in programming.

Try:

document.getElementById('myElement').style.display =
(hide) ?'none' :'block';

Please show your code, minimalistic that is.

I do not understand how that works.

I use to do :

document.getElementById('myElement').style.display =
document.getElementById('myElement').style.display ==''?
'none' : '';

not unless you code it yourself what have you tried.
heres how I would do it:
you take the value of the element and add it to the end of the text
box value and put it inside an array.
if they then click on a few things and then remove something they had
previously added, you must take the position of the element in the
array with the value just removed (which must be unique) and remove
the appropriate string from the position it will be in the text box
after adding together the string lengths of the values that were
before that element in the array.

have two classes called hide and show
these have display:none, and display:block
set the classNames of elements according to what is clicked, if you
need multiple things to appear dissappear either use a div surrounding
them, or set a function to take an array of element names and show/
hide them.
remember to check what state they are in before you act on them if you
have any overlap between single and groups of elements

You did not misunderstand anything. It does not work as is.

I use to do :

document.getElementById('myElement').style.display =
document.getElementById('myElement').style.display ==''?
'none' : '';

Same thing I do. Well, basically. I still explicitly set 'block' or
'inline' or whatever for that matter. Only to make sure it is set back
to its original style.

That is a toggle, 'hide' returns any boolean result.

A toggle was not asked for, Stéphane.

Why should it be defined, It is not a complete code.

Peut-être:

Le poseur original n'a pas posé sa Q sur une function basculante.

"... 'hide' returns any boolean result"

.... 'hide' est une variable et retourne une valeur booléene.

Ho? possibly, and then ?

Have we to answer exactly ? Can't we show other solution(s) ?

The OP asked :

2/ Also, what is the best way to hide / unhide form elements when

others are selected ?

a toggle could do the stuff,
a toggle was I thought you gave as code
(it was only suggested and answer's built was out of my understanding )

They can gives some atrocities !
Curiously, a wrong result remade in good language and re-submited
can give back what was submited in first ...
