What is the correct way to find all the form elements in a particular
div? I'd like to be able to loop through them and disable them. For
example:
<form>
<div id="div1">
<input type=text name="a">
<input type=text name="b">
</div>
<div id="div2">
<input type=text name="c">
<input type=text name="d">
</div>
</form>
I'd like to be able to pass "div1" to a function and have it disable
text boxes a and b.

One option is to use the standard DOM methods:-
var eDIV=document.g etElementById(" div1");
var cINPUTS=eDIV.ge tElementsByTagN ame("INPUT");

With the W3C DOM (implemented in IE 5 and later, Netscape 6 and later,
Mozilla 1.0 and later, Opera 7 and later and other newer browsers like
Safari) every element has a method
getElementsByTa gName
to find descendant elements by their tag name thus if you have an
element object then
elementObject.g etElementsByTag Name('input')
return a node list with all descendant elements with the tagName input.
So you can loop through that node list e.g.
var inputElements = elementObject.g etElementsByTag Name('input');
for (var i = 0; l = inputElements.l ength; i < l; i++) {
inputsElements[i].disabled = true;
}
Of course there are other form controls like textarea or select elements
for which you would need to look with additional calls to
getElementsByTa gName.

I think you may start from the proper form layout. Form elements and
DIV's are not in direct parent-child relations: they just can be forced
to overlap each other like in your case. It may hurt you during dynamic
form manipulations. The rest as suggested by the previous poster.
<html>
<head>
<title>Form</title>
<meta http-equiv="Content-Type" content="text/html;
charset=iso-8859-1">
<script type="text/javascript">
function getBlock1() {
var d = document.getEle mentById('fs1') ;
var a =d.getElementsB yTagName('INPUT ');
// ...
}
</script>
</head>
<body onload="getBloc k1()">
<form>
<fieldset id="fs1">
<legend>Block 1</legend>
<input type=text name="a">
<input type=text name="b">
</fieldset>
<fieldset id="fs2">
<legend>Block 2</legend>
<input type=text name="c">
<input type=text name="d">
</fieldset>
</form>
</body>
</html>
Thanks to everyone who has helped me. Here's something I don't
understand:

Wait a minute! Any large form is going to *have* to be broken up by
divs, spans, tables, etc. I can't believe that's wrong! It's
practically required!
Are you saying that you never have anything but form elements between
the begin and end form tags? How do you, for example, line up a bunch
of checkboxes into columns? A few divs, floated right, is perfect for
something like that.
it's obvious you know what you're talking about so I'm not arguing.
I'm just kind of blown away by this.

Utter nonsense. That HTML is completely fine and valid, even by the
strict DTD.

So another VK 'contribution' that can only hinder the OP's

Martin Honnen knows what he is talking about and I suspect that Julian
Turner knows enough not to talk about what he doesn't know, but VK is a
very different story. In statistical terms you would be better off (more
often than not correct) assuming that anything VK says is false,
inadequate or misconceived.
so I'm not arguing.
I'm just kind of blown away by this.
Feel free to argue, is it were true there would be something to back it
up.

Don't get so exaggerated. My suggestion was about the *posted code*
where I see two blocks of the same form which you're trying to separate
visually(?) and functionally(?) .
The golden rule is to try to solve the problem in easy and possibly
correct way first.
If not - then try to solve it in a not so easy and possibly
non-standard way.
For the posted code table layout was not requested, so internal
subdivisions using <fieldset> were totally logical *and* more correct
then <div> because <fieldset> *is* direct form's child and direct
parent to its elements. Just check and compare myDiv.form and
myFieldset.form property.
Naturally in design one *has* to use tables for nearly any form for
nice looking scalable layout. I'm personally using it since 1997and
over the passed years I had to place form elements to the most
fantastic places - not only tables. :-)

Naturally, you meant to say:
"...in design one *has* to use divs/spans for nearly any form

Tables are in a semantic document for presenting tabular data,
not for positioning elements.
For that, we have css.

For that, we have css.
CSS is not suitable for scaleable layout, this path has been explored
throughout during 4th versions on positioned elements and on the Java
1.x GridBagLayout
It failed to work and abandonned now in favor of the original
"invisible table" technique.
When did you last time visited the Web?
But it doesn't mean that we need to use table *every single time* some
positionning is needed. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

If yes, how can I avoid it?

Ugh....
All classes are copy by reference, even if you use "ByVal" and NOT "ByRef"
it's still a copy by reference.
Of course, as a consequence, if you change any values of the object you
passed in, the original object is affected.
I expect this with arrays, but not with single objects being passed "ByVal"
to functions....
Is there a sane to get "ByVal" passing of parameters? (copying fields is not
