I have 2 list boxes - one to fill the second one based on the selection, or
move all items. You can remove the selection (or all items) from the second
one to place it back in the first one. I expanded my horizons and thought
to use script based on the js node operation appendChild(). It seemed so
clean and easy to follow. Works beautifully in IE, but Firefox sees the
value for a nanosecond but doesn't put it in the box. This is the relevant
js:
function addSide(){
var addIndex = document.forms[0].sides.selected Index;
if (addIndex >= 0)
{
document.forms[0].selectedSides. appendChild(doc ument.forms[0].sides.options( addIndex));
}
}
function delSide(){
var selIndex = document.forms[0].selectedSides. selectedIndex;
if (selIndex >= 0)
{
document.forms[0].sides.appendCh ild(document.fo rms[0].selectedSides. options(selInde x))
}
}
function addAll(){
var len = document.forms[0].sides.length -1;
for(i=len; i>=0; i--){
document.forms[0].selectedSides. appendChild(doc ument.forms[0].sides(i));
}
}
function delAll(){
var len = document.forms[0].selectedSides. length -1;
for(i=len; i>=0; i--){
document.forms[0].sides.appendCh ild(document.fo rms[0].selectedSides( i));
}
}
Is there a way to make it work for FF, or do I need to just start over and
not use appendChild()? Is there a better way?
Thanks,

Did you get an error message in the error console? Get the Firebug
extension and you will won't miss them.

This is the relevant
js:
function addSide(){
var addIndex = document.forms[0].sides.selected Index;
if (addIndex >= 0)
{
document.forms[0].selectedSides. appendChild(doc ument.forms[0].sides.options( addIndex));
This should produce an error message something like:
"document.f orms[0].sides.options is not a function"
The options object is a collection, you want to refer to its members by
index using square bracket notation:
...appendChild( document.forms[0].sides.options[addIndex] );
and so on for the rest of your script.

Hi Rob,
Perfect. I knew it had to be something simple - wonder why the original
code used parens rather than brackets? Good ol' IE - it'll accept anything
:-) Thanks for the link - I haven't used FF much but need to start because
I've seen that it has what appear to be good extensions. Never used IE until
3 years ago - always used Netscape - but my college required IE for online
classes and got in the habit.
Thanks a bunch,
Christina

I wrote this pretty slick DHTML table that lets you add/remove rows and show/hide columns on the fly. It works perfectly in IE7, but it doesn't behave in Firefox 2.0.0.4. You can see it in action here:
http://www.phreelancer.com/dyn_table/
If you start to add/remove rows and then show/hide columns a few times in FF, you'll see that some table cells are bundled together or that some hidden cells don't get collapsed (but are still empty)....

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
