Hi,
FWIW, I think you can avoid the branching.
To remember an element's position and then remove it:
* * * *
function saveAndRemoveElement(elm) {
var saved;
saved = {
elm: elm,
parent: elm.parentNode,
next: elm.nextSibling // <= May be undefined, that's okay
};
elm.remove();
return saved;
}
* * * *
To restore it:
* * * *
function restoreSavedEelement(saved) {
saved.parent.insertBefore(saved.elm, saved.next);
}
* * * *
Node#insertBefore inserts at the end of the second parameter is
undefined.
The only Prototype-ism in the above is elm.remove().
Hope this helps,
