Hi Chris, Thanks for the reply. As you illustrate, trying to be definitive in this situation seems pretty much impossible. It's appreciated.

Hi Kevin, and thanks. I think I've found a simpler way to handle this. Please see my next reply to Chris Knowles.

RE: [WSG] Behavior Effecting Presentation or Structure - Precedence?
Hi Chris,
(My apologies to the list moderators if this is getting to Behavior orientated.)
If so, then I'm not sure there's ever really a choice. e.g. in your
example you would need to use both methods to cover a) and b):
a) would need you to set the style to display: none
and b) would need you to try and remove the node
I don't know if this will satisfy the conditions you raised, but combining the
two methods with an if else statement may make sense:
/*
function remove()
{
if (remove)
{
var div = document.getElementById(remove);
div.parentNode.removeChild(div);
}
else
{
document.getElementById(remove).style.display = none;
}
}
*/
Kind regards,
Frank

Frank,
try this...
if (typeof document.removeChild != undefined) {
var div = document.getElementById(remove);
div.parentNode.removeChild(div);
} else {
document.getElementById(remove).style.display = none;
}
if you're doing a lot of checking throughout your code though set a
global flag...
var DOM = document.getElementById ? true : false;
and then...
if (DOM) {
...
}
email me direct if you want to discuss as it's probably off topic by now.

[WSG] Behavior Effecting Presentation or Structure - Precedence?
Hi All,
I hope everyone has had a pleasant, restful and blessed holiday.
May I pose a question regarding the Behavior layer with its intended effect on
presentation or structure? I'm looking for an answer according to best practice
and standards, as to which layer should we target to achieve a desired effect.
Scenario:
I have a div whose contents are only to be seen when scripting is not available
(I don't employ the noscript element). The div is given an id attribute and
value (remove) acting as a hook to an external javascript function which
performs the intended behavior. So far, so good. The function can affect either
the style or the structure of the div and its contents. Both approaches work
equally well. My question is which is the preferred/correct layer to target
when we have a choice? The functions are exhibited below:
// - behavior affects the presentation layer
function remove1()
{
document.getElementById(remove).style.display = none;
}
/
/ - behavior affects the structure layer
function remove2()
{
var div = document.getElementById(remove);
div.parentNode.removeChild(div);
}
/
Am I correct in thinking that behavior should target structure first, and if
necessary, presentation second?
Kind regards,
Frank M. Palinkas
