Expandable Sidebar Menu Screencast

Posted on by

This is the first (of hopefully many) screencasts that will provide a quick tutorial to a simple demo of jQuery in action. I plan on doing at least 2-3 more based upon the talks that I’ve given lately – hopefully I can trickle those out over the next week(s) or so. (Oh, and sorry if I sound tired – that’s because I am.) Enjoy!

jQuery 1.0.3

Posted on by

Another bug-fix release is ready for all to enjoy! It is highly recommended that you upgrade right away. As always, if you spot a bug, please add it to the bug tracker.

As with the last release, jQuery 1.0.3 is featuring only bug fixes – leaving all API additions/changes/deletions until the next full release: jQuery 1.1.

Once again, Jörn Zaefferer did an incredible job really keeping on top of the bugs, fixing the vast majority of them. Much of this release was made possible by him.

Download Now:

This release includes a new package: A complete zip file of everything associated with this release. This includes three versions of jQuery (Regular, Lite, and Packed), the test suite, and all the documentation. Now you don’t have to build it yourself just to have your own copy.

Tickets Closed:

jQuery Button Contest – Many Prizes!

Posted on by

Update: The contest is now closed! I would like to thank everyone for their submissions. We’ll begin the judging process very soon.

To encourage people to promote the jQuery project, and get as many people involved in the community as possible, we’re holding a contest to build a “Powered by jQuery” button. Having a nicely designed button will be a good way for jQuery users to build more awareness about the project, while having something that looks cool on your site!

The Rules:

  1. The contest will run until November 3rd. Winners will be announced November 5th.
  2. All entries must must be optimized for the web (8-bit PNG) and images should be no bigger than 173×31 (example).
  3. The jQuery team will have the right to the use the submissions anyway they wish. This will prevent any copyright issues in the future. The winner must also be able to provide a PSD (or AI) file so that the image can be maintained in the future.
  4. Prizes will be awarded for 1st, 2nd and 3rd place submissions.
  5. The general jQuery community will do the final voting, moderated by John Resig, creator of jQuery, and Rey Bango.
  6. You should make use of the jQuery hat logo in your button (you’re free to re-draw it, as necessary). If needed, here’s a raw PSD of the hat logo.

The Prizes:

  1. First Place Prize: Two Books – Ajax Design Patterns and John Resig’s upcoming Pro JavaScript Techniques
  2. Second Place Prize: One Book – Foundations of Ajax
  3. Third Place Prize: $10 Cash to a PayPal account of your choosing!

The prizes will be shipped anywhere in the world via regular post.

All submissions should be made in the comment section of this posting via a standard hyperlink. Make sure that you provide a valid email address when submitting your entry.

This is your chance to really help expand the jQuery community by creating a top notch button that will get a ton of exposure. Good luck to everyone!

Friends of Firefox – Mozilla utilizes jQuery.

Posted on by

Mozilla just released http://www.worldfirefoxday.com/, a site to thank everyone who contributed in world firefox day 2006. The site allows users to search for friends names and they are displayed in an interesting fashion.

The script is a combination of the Rotator script and some slick AutoComplete which powers the search.

Start typing a name slowly to see the results being filtered and loaded into the rotator in real time. Then, if the results number more than 20, you are able to “page” through them. The script supports a “previous” button, but it has been hidden.

Zebra Table Showdown

Posted on by

As a follow-up to the previous event selector showdown comes a new Zebra Table Showdown.

The Challenge:

Making all tables on a page have striped (“Zebra”) backgrounds (different coloring on every odd row).

The Rules:

  • The odd/even styling should be done by adding a class for the ‘odd’ numbered table rows.
  • This must be able to work on multiple tables. (It’s not as simple as finding all rows then going through every odd one, otherwise an even row could become highlighted in the next table).
  • The code should be done as elegantly as possible, using as much of a libraries’ functionality as possible. Speed is not an issue.

Intended Result:
zebra-fig1.gif

Plain DOM Scripting: (demo)

var tables = document.getElementsByTagName("table");
for ( var t = 0; t < tables.length; t++ ) {
  var rows = tables[t].getElementsByTagName("tr");
  for ( var i = 1; i < rows.length; i += 2 )
    if ( !/(^|\s)odd(\s|$)/.test( rows[i].className ) )
      rows[i].className += " odd";
}

Note: This includes a check to make sure that the 'odd' class doesn't already exist on the table row. This is taken care of by all modern libraries.

Yahoo UI: (demo)

var tables = document.getElementsByTagName("table");
for ( var t = 0; t < tables.length; t++ ) {
  var rows = tables[t].getElementsByTagName("tr");
  for ( var i = 1; i < rows.length; i += 2 )
    YAHOO.util.Dom.addClass( rows[i], "odd" );
}

Note: Although, their own developer site disagrees.

Dojo: (demo)

var each = dojo.lang.forEach;

each(document.getElementsByTagName("table"), function(table){
  each(table.getElementsByTagName("tr"), function(row,i){
    if ( i % 2 == 1 )
      dojo.html.addClass( row, "odd" );
  });
});

Note: A common function was assigned to a variable in order to make the code shorter.

Prototype (1.4.0): (demo)

$A(document.getElementsByTagName("table")).each(function(table){
  $A(table.getElementsByTagName("tr")).each(function(row,i){
    if ( i % 2 == 1 )
      Element.addClassName( row, "odd" );
  });
});

Mochikit: (demo)

var byTag = getElementsByTagAndClassName;

forEach( byTag("table"), function(table) {
  var rows = byTag( "tr", null, table );
  for ( var i = 1; i < rows.length; i += 2 )
    addElementClass( rows[i], "odd" );
});

Note: A common function was assigned to a variable in order to make the code shorter.

Prototype (1.5.0): (demo)

$$("table").each(function(table){
  Selector.findChildElements(table, ["tr"])
    .findAll(function(row,i){ return i % 2 == 1; })
    .invoke("addClassName", "odd");
});

mootools: (demo)

$$("table").each(function(table){
  $ES("tr", table).each(function(row,i){
    if ( i % 2 == 1 )
      row.addClass( "odd" );
  });
});

jQuery: (demo)

$("tr:nth-child(odd)").addClass("odd");

If you feel as if you have a more elegant solution than the ones posted here, please post them below so that the listing can be updated.


New Submissions:

These are new entries that have been submitted by other readers.

AJS: (demo)

AJS.map(AJS.$bytc("table"), function(table) {
 AJS.map(AJS.$bytc("tr", null, table), function(row, i) {
   if ( i % 2 == 1 && !/(^|\s)odd(\s|$)/.test( row.className ) )
     AJS.setClass( row, "odd" );
 });

Prototype 1.5.1: (demo)

$$('tr:nth-child(odd)').invoke('addClassName', 'odd');

Minor API Change in 1.0.2

Posted on by

I forgot to mention in the 1.0.2 release notes, the other day, that there was a minor API change. This was a mistake, as we should’ve held off on making an API change until the next major release (jQuery 1.1).

As summarized by Steven Wittens, here is the premise behind the change:

In jQuery 1.0.2, the first argument to the ‘success’ callback has been changed to return the actual data rather than the XMLHttpRequest object. Use the ‘dataType’ argument to $.ajax() to control how the data is returned. Note that jQuery can now parse XML, JSON and JavaScript for you this way.

jQuery 1.0.1

$.ajax( {
  success: function (xmlhttp) {
    var data = $.httpData( xmlhttp );
    // 'data' holds the response data from the server
  }
);

jQuery 1.0.2

$.ajax( {
  success: function (data) {
    // 'data' holds the response data from the server
  }
);

Thanks, Steven, for the synopsis – and sorry, everyone, for the inconvenience!

jQuery 1.0.2

Posted on by

jQuery 1.0.2 is now ready for consumption! This release is a huge bug fix release – and it is highly recommended that you upgrade right away. As always, if you spot a bug, please add it to the bug tracker.

In addition to having a better test suite, a big push for this release was to have better cross-browser compatibility for common tasks (such as AJAX operations). Functionally, however, no major features have been added to this release (although, expect some new code come 1.1).

I’d like to take this opportunity to introduce everyone to Jörn Zaefferer. Much of this release was made possible by him. He’s responsible for completely overhauling the test suite (it now has over 260+ tests!) and for fixing the majority of the current bugs and enhancements (over 60 of them!). If you want someone to thank for this release, it should be him.
