It might be something easy that I'm overlooking, but I don't see what
I'm looking for as part of either Enumerable or Array.
I've found myself needing to set attributes on arrays of Elements. I
know this is trivial with each(), but I'm looking for a cleaner way
to do it. The idea is similar to Enumerable.pluck(), but as a setter
instead of a getter. Perhaps there is already an easy way to do it
that I'm missing. I'd call it Enumerable.apply() or .setEach()/
extendEach().
apply: function(iterator, attribute, value) {
return this.map(function(item, index) {
item[attribute] = value;
});
},
Use case:
$$('#myFormId input').apply('disabled', true);
$$('#myFormId input').apply('checked', '');
It could be made a bit more robust with something like this:
apply: function(iterator, hash) {
return this.map(function(item, index) {
Object.extend(item, hash);
});
},
Even better, the function could be reworked to auto-detect the number
of parameters passed (or whether the first is a string or an object),
and act accordingly.
Useful? Not useful? I'm an idiot and overlooked something simple?
