World's best javascript library now gets better.

  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.)

      I tried Jaxer but it seems to not follow the usual MVC pattern we all know and love. I don't know if it supports method chaining goodness ala jQuery though.

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 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_removes_all_browser_sniffing/ 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.)
    - jeresig 18y ago
      Unfortunately it's not as simple as it is with events. With events you have the advantage of binding to a single point (e.g. the document node) and using the native event bubbling that exists in all browsers to capture any event that occurs on the page. This way we can detect a click on a new DOM element that we haven't seen before. We don't have that luxury with CSS. There's no universal way for all browsers to let JavaScript know when a new element has been added to the page - or that it's been moved. There's the W3C DOM mutation events but they aren't implemented everywhere.

I'd like a more expansive AJAX API that is capable of handling HTTP headers.
- jeresig 18y 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 ... }); More info: http://docs.jquery.com/Ajax/jQuery.ajax#options http://docs.jquery.com/Ajax/jQuery.ajax#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.
    - mmj 18y ago
      That is a pretty niche feature, I personally wouldn't do something like that. Check out getResponseHeader() if you are so inclined. As for the errors, there are many ways to check for "ajax" errors, for one thing you can check the status or statusText property.
      - ars 18y ago
        Niche? I guess you don't use json. jquery already autodetects xml, why not json too? It's not even hard - it's right in the content type. I know how to detect errors, that was hardly my point. I was suggesting an improvement, not tech support.
        mmj 18y ago
        You don't have to eval xml.

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.
- jeresig 18y ago
  Do you have any examples? Have you filed any bugs in the jQuery bug tracker? http://dev.jquery.com/ http://dev.jquery.com/
