Roundabout for jQuery by Fred LeBlanc It’s ready-to-go straight out of the box, but if you want to get crazy, Roundabout is highly-customizable with an extensive API that allows for some pretty amazing results. Roundabout requires jQuery (at least version 1.2, successfully tested through version 1.7.2). It works in all major modern browsers and even some of the older, not-so-modern ones. It’s open source and released under the BSD license, meaning that it’s free to use in your personal or commercial projects. See Roundabout In Action Add-Ons Roundabout is equipped to play nicely with a couple of other plugins if they’re made available. Roundabout Shapes by Fred LeBlanc Roundabout can move in more ways than just a turntable. But That’s Not All! The list above is only a list of the plugins that have support baked in, but Roundabout will play nicely with many other plugins.

Instead of getting a jQuery copy, you should definitely take advantage of Google’s “generosity” and directly load their copy: » Source Validate a date of birth using jQuery Validating dates of birth are a common task on websites that have content available only for users 18+ years old. $("#lda-form").submit(function(){ var day = $("#day").val(); var month = $("#month").val(); var year = $("#year").val(); var age = 18; var mydate = new Date(); mydate.setFullYear(year, month-1, day); var currdate = new Date(); currdate.setFullYear(currdate.getFullYear() - age); if ((currdate - mydate) < 0){ alert("Sorry, only persons over the age of " + age + " may enter this site"); return false; } return true; }); » Source Make sure an image has loaded properly How do you know if an image has been properly loaded? $('#myImage').attr('src', 'image.jpg').load(function() { alert('Image Loaded'); }); » Source
Using jQuery's SlideUp() and SlideDown() Methods With Bottom-Positioned Elements jQuery makes the creation of dynamic user interfaces easier than ever before. A few of the convenience methods that I use every single in my web application development are slideDown() and slideUp(). These are perfect for showing and hiding content in a non-jarring manner. I fell victim to this narrow-sightedness just last week. After I got this approach to work, including the offset calculation and re-positioning that I needed to perform prior to slide-up, I had a "well d'uh" moment! Once I had this realization, it made so much sense that I was, in fact, more than a little embarrassed that it didn't occur to me sooner.
JavaScript: Resizing text to fit in a container This span is too big for this div This is a simple problem and a simple solution. Often in the world of dynamic data we find ourselves with data that is larger than the container. There are ways of handling this like a scrolling div or adding ellipses to chopped of text, but what if you absolutely must see all of the text and are willing to change to font size to accomplish this? function adjustHeights(elem) { var fontstep = 2; if ($(elem).height()>$(elem).parent().height() || $(elem).width()>$(elem).parent().width()) { $(elem).css('font-size',(($(elem).css('font-size').substr(0,2)-fontstep)) + 'px').css('line-height',(($(elem).css('font-size').substr(0,2))) + 'px'); adjustHeights(elem); } } Here's the same div as above with the script applied: You can modify the fontstep variable to resize at a faster rate if you want. EDIT: I added a bit of a timeout to give the webfont time to load first...
Create a Sticky Navigation Header Using jQuery Waypoints In this tutorial, we'll be creating a navigation bar that stays with you as you scroll down — and we'll also throw a gimmick or two into the mix to polish it off. Republished Tutorial Every few weeks, we revisit some of our reader's favorite posts from throughout the history of the site. This tutorial was first published in March of 2012. Introduction “Everybody loves ribbons” Chris Coyier says when discussing the virtues of the :before and :after pseudo-elements. Ribbons are liked for a reason, though — they break the mostly flat design paradigm that we’re traditionally bound to, and they’re one of the few visual elements to do so in an inconspicuous way. What We’ll be Doing In this tutorial, we're going to use one of HTML5's new elements, the nav tag, as a container for a horizontal list of links. Step 1: The Box I'm sure you're already familiar with the various new elements that have been introduced with HTML5. We’re going to have to give our navigation bar an explicit width. Cool, huh?
