This method appears to be missing something that would be quite useful. An option so that the select() method would only look through immediate children, exactly how childElements() and decendants() differ. Unless there is already a method to do this, I have not seen..

You can simply rely on the CSS child combinator. Instead of using ''#anyId .anyClass'' you can use ''#anyId > .anyClass'' This will look for .anyClass elements through the immediate children of #anyId.

That works fine with $$, but if you have an element already there and
want to select between it''s immediate children, you can''t do
element.select("> .active")
Best,

Hum, indeed, didn''t think of that...!
But
element.immediateDescendants().grep(new Selector("#some .selector"));
is kinda ugly, huh?
Prototype guys should put a little sugar on this matter =)

In a nutshell, supporting something like this could lead to unnecessary complications in prototype''s source.

Fabio, I was thinking something on the lines of String.prototype.match = String.prototype.match.wrap(function(proceed, obj) { if (Object.isElement(obj)) return new Selector(this).match(obj); return proceed(obj); }); And then you can do element.immediateDescendants().grep("#some .selector"); Even more, alias immediateDescendants as children and then it''s element.children().grep("#some .selector"); which is a little nicer (and concise) IMO. -Nicolas --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

"childElements" more precisely. Element#children is a native Safari method.

you could build a filter function and iterate over the elements child
nodes.
var filter = function(ele){
return ele.nodeType == 1 && $
(ele).hasClassName(".active");
};
$A(ele.childNodes).findAll(filter);
