[Prototype-core] Re: $$ function needs context attribute?
Hi,
That's already achieved using Element#select (formerly,
Element#getElementsBySelector).
For exemple:
$('foo').select('div.bar', 'a.baz');
is strictly equivalent to:
Selector.findChildElements($('foo'), 'div.bar', 'a.baz');
which is what your modified version of $$ wants to achieve.
In this regard, I don't see a compelling reason to complexify
Prototype's API by adding a functionality that's already present in a
clearer and more OO way.
Regards,
Tobie

[Prototype-core] Re: $$ function needs context attribute?
What I want is quite easy to achieve:
function $$() {
if(arguments[arguments.length-1].tagName)
return Selector.findChildElements($A(arguments).last(),
$A(arguments).slice(0,-1));
else
return Selector.findChildElements(document, $A(arguments));
}
I think this can make the $$ function to be much more flexible.

This snippet doesn't really do anything ...

The method has been renamed to "select" in 1.6.0.
I don't see what all the fuss is about, can't you just try and use this
method instead of complaining how you would rather do it some harder way?
Thanks.

$$("").each(function(node){
node.getElementsBySelector("a.myclass");
})

Is this what you mean?

Oh, the "select" method, I haven't use it, and the context is
important for the css selector, and in the case
Selector.findChildElements supports the context, So only change the $
$ function and to check whether the last argument is HTML element or
not is enough. And context is really very important for css selector,
it make the selector much more flexible.especially in the
$$("").each(function(node){
$$("",node).doSomething()
})

We use "Element#select" to constrain the lookup to a certain element:
$("foo").select("img")
We discussed adding a context argument to $$ a while ago, but it just didn't
turn out worthwhile, I guess.
