Re: [jquery-dev] Re: Will the live() method be improved in 1.4?
I've already landed the commits - looks great - thanks! (I'll close
the ticket once my network stops flaking out.)

I opened a ticket: http://dev.jquery.com/ticket/5470

Commit also includes context inside liveHandler (it is a too small
change to make a separate commit).
Component is unfiled. Please tell me if I made mistakes opening this
ticket.

1. Calling closest, context argument still is not used.
I was unable to find the proper ticket. Would I open one?
2. Storing how much a parent is close to an element with data API is
an big overhead. An jQuery.lastCloser or something similar would be
enough. Also it would speed up sorting inside liveHandler with
somethin like this:
...
elems.push({ elem: elem, fn: fn, closer: jQuery.lastCloser });
elems.sort(function( a, b ) {
return a.closer - b.closer;
});
I'd appreciate tickets/patches for both of these - they both sound
like great additions.

Meyer, delegate was my first candidate too but I was worry that it was overused :). Seams that I was wrong. Will update it with delegate ASAP. --Robert On 6. stu. 2009., at 02:42, Justin Meyer justinbme...@gmail.com wrote: How about $(#something).delegate(.thing,click, func).

Re: [jquery-dev] Re: Will the live() method be improved in 1.4?
Also, @robert, my solution supports the following notation, similar to
yours but using the familiar jQuery syntax (before/after DOMReady):
$.live(#mySelector, click, fn1)
.live(#mySelector, mouseover, fn2)
...;
I understand the logic behind you wanting a $.live method (for the
edge cases where, presumably, you have hundreds or thousands of
elements that you're trying to match - and you don't want to run the
initial selector). Although there's a lot that I don't like about it:
- You are now passing in a selector to a non $(...) or .foo() method.
This goes against all the conventions that the library has - when you
interact with DOM elements, stay within the jQuery set.
- The only case where this matters is in a fringe case (namely, only
when you use both a complicated selector AND run it in IE 8, since
all other browsers are using querySelectorAll) - but the existence of
the method in jQuery would remove the need to ever use the one method
that everyone should use.
- Presumably since you're in a situation where you're really caring
about performance - then why are you using .live to begin with?
Shouldn't you be binding lower in the document? This is why the
closest method was added, to make tasks like this even easier.
I would simply recommend: If you're in a situation where you're
starting with a critical number of elements on your page, enough to
ruin your pages' overall performance, then you should use a basic form
of event delegation, like so:
$(#someRootTable).click(function(e){
$(e.target).closest(td.foo).each(function(){
// Your code goes here.
});
});
Which is really what you should be doing anyway (live method or not).

Re: [jquery-dev] Re: Will the live() method be improved in 1.4?
What about something like this:
$.live = function(selector, type, callback) {
$.fn.live.call({ selector: selector }, type, callback);
}

Hi John,
Thanks for the quick feedback
IMO, I think it would be handy to have something like $.live as I can
see where it would be of great benefit when working with a lot of
elements.

Re: [jquery-dev] Re: Will the live() method be improved in 1.4?
$(#someRootTable).delegate(td.foo, click, function(e){
// Your code goes here.
});
Would be easer and safer because the event will be handlet only by
td.foo elements inside #someRootTable.

Re: [jquery-dev] Re: Will the live() method be improved in 1.4?
If you want to limit, just do this (using the nightlies):
$(#someRootTable).click(function(e){
$(e.target).closest(td.foo, this).each(function(){
// Your code goes here.
});
});
Still pretty simple and requires no additional functionality. I may
just write this up as an example and add it to the live and closest
docs.

Re: [jquery-dev] Re: Will the live() method be improved in 1.4?
I suppose you will need an return false; too at the end of the
handler...
