World's best javascript library now gets better.

bprater2• 18 years ago

Mmm.. jQuery makes me giddy. This week, I wondered if something akin to jQuery but running server-side would be useful. (Modifying the DOM before it hits the client.)

Can anyone tell me what new features can still be added to jquery? It looks pretty feature complete to me.

I wish they focused more on jquery-ui, as I find that a bit lacking at the moment.

We aren't really talking about the features of this release, yet, since we want people to focus on testing (to make sure we didn't break anything). But here's a rough breakdown of the code that's in:

New Selector Engine (Sizzle: http://github.com/jeresig/sizzle/tree/master). Much faster than previous engine, going to be in many of the major libraries.

No more browser sniffing (currently being discussed here: http://www.reddit.com/r/programming/comments/7l2mr/jquery_re...).

.closest() method - extremely useful for event delegation.

    // Returns this or closest ancestor that matches selector
    $(this).closest("div");

.live() - Super-simple event delegation.

    // Will handle clicks on all elements that match selector
    // even if new ones are added later
    $("#foo > div").live("click", someFn);

.offset() rewrite - significantly faster, uses no browser sniffing.

.hide()/.show() rewrite - 50% - 200% faster.

.append/prepend/before/after rewrite - 10-15x faster.

While the biggest feature of this release is performance, the new event delegation methods are going to be super-useful.

As to jQuery UI - there are multiple teams within the jQuery project - the core jQuery team works on the jQuery library and the jQuery UI team works on jQuery UI. In their last update (about a week ago) the UI team said that UI 1.6 final was going to be out before the end of the month.

Would you consider adding something like .live() for CSS? (Or maybe it already does that.)

brandonkm• 18 years ago

I'm really happy with these recent upgrades. Especially in regards to event delegation, not having an effective baked in solution for event delegation was one of my biggest complaints about the previous releases.

bprater2• 18 years ago

Yum, I'm glad .live() is in the core.

I'd like a more expansive AJAX API that is capable of handling HTTP headers.

jeresig5• 18 years ago

"capable of handling HTTP headers" - can you expand on this a bit?

Right now you can set HTTP headers in jQuery like so:

    $.ajax({
      beforeSend: function(xhr){
        xhr.setRequestHeader("Accept","application/json");
      },
      ... other options ...
    });

I'd like it that if the server sent back Content-type: application/json then jquery would automatically put it in json, and not require dataType: 'json'.

And it would really be nice if the "simple" ajax functions also allowed doing something if there was an error.

Has anyone ever run into issues manipulating table rows or columns? I have on several occasions experienced problems with cells not being properly displayed after appending or toggling.

jeresig5• 18 years ago

Do you have any examples? Have you filed any bugs in the jQuery bug tracker? http://dev.jquery.com/
