See, the important point, and the reason why I made this addition, is
for the fact that I'm trying to standardize how jQuery works and the
order of arguments for a method. The idiom that I'm molding is:
.method( Hash, arg1, ..., argN, ContextFunction )
If a method takes a hash, you'll know that it's the first thing in
there. If it takes a context function - it'll always be last. With
that in mind, adding on context functions to virtually all methods
just makes sense (we were nearly there to begin with).
This way, a user can call .load(), .submit(), .parent(), .find(), etc.
etc. and know that the last argument can be an optional function that
will be executed within the set's context.
So, with .filter("foo",function) I'm taking the opportunity to remove
the need for:
.filter("foo").each(function(){
}).end()
Which is good because it's very common, and way too verbose. It's also
the same reason why I added the context function to $(...), to remove
that common .each() need. When people write the above code, they're
effectively building a non-destructive area in which they can work.
And it makes sense that way.
A lot of what you're doing can depend on how you write your code too,
and how you indent it, for example:
$("div.test")
.find("ul", function(){
$(this).hide()
if ( $("#newList:hidden").length )
$("#newList").show('fast');
})
.find("form")
.submit(function(){
return false;
})
.end();
I'm not confused by the above, although, I am steeped in the code
pretty good, so who knows. Comments are definitely appreciated.
