[Phpwm] Javascript / IE / prototype issues.

[Greg Jones]

If I have some time tomorrow, I will give a longer answer if you're still  
wanting one, but a couple of your points are quick:

I very rarely use Insertion.X as they're not much use. If you're using  
scriptaculous already, then Builder.node() is useful (you could just use  
the Builder.js part). Prototype has code in SVN for 'var div = new  
Element('div',{className:'some_class',id:'some_id'});' if using that's an  
option. It looks nice, but haven't tried it yet myself.

passing 'true' to cloneNode() should cause it to do a deep copy.

I tend to add option-nodes to the options array of the select:

$('select_id').options[$('select_id').options.length]=new_option;

I seem to remember a time when adding the options to the select, before  
the select is added to the document worked, when the other way round didn't


If you want to include/paste-bin the html of the table you're using, then  
if (when) I get bored tomorrow, I can check that what I reply with  
actually works :)
