Well, writing
myElem.conditionalAdopt(elema, elemb, elemc);
is a couple of characters shorter than writing
if (elema) {
myElem.grab(elema);
}
if (elemb) {
myElem.grab(elemb);
}
if (elemc) {
myElem.grab(elemc);
}
(even when minified), so if you use this pattern a lot, it could pay off. :)
Pragmatically, to reduce DOM manipulation, wouldn't this implementation
of the function be somewhat more efficient:
Element.implement({
conditionalAdopt: function() {
var els = [];
$A(arguments).each(function(item) {
item = document.id(item);
if (item) els.push(item);
}
return this.adopt(els);
}
});

Haven't heard anyone saying that since 1999 - you know, 56K modems and
all :-)

Anyone ever implemented something like this? or have a nicer
way of
doing it?
http://mootools.net/shell/KPPNg/
Element.implement({
conditionalAdopt: function(){
if(Array.prototype.splice.apply(arguments,[0,1])[0]){
Array.flatten(arguments).each(function(element){
element = document.id
<http://document.id>(element, true);
if (element) this.appendChild(element);
}, this);
return this;
}
return this;
}
});
