jQuery Fundamentals :: JavaScript Basics jQuery is built on top of JavaScript, a rich and expressive language in its own right. This section covers the basic concepts of JavaScript, as well as some frequent pitfalls for people who have not used JavaScript before. While it will be of particular value to people with no programming experience, even people who have used other programming languages may benefit from learning about some of the peculiarities of JavaScript. Here's a simple JavaScript program that adds a message to the page: In the above example, we use a function called log. You can try running this program by clicking the and it will copy the code to the built-in editor automatically. It's OK if you don't understand everything that's going on in this program; in the rest of this section, we'll talk about variables, functions, and several other building blocks of JavaScript. A comment about comments Comments can be a useful tool for explaining what's happening in a piece of code. The building blocks of JavaScript Objects
Leaflet - a modern, lightweight JavaScript library for interactive maps by CloudMade YUI Theater: Douglas Crockford, The JavaScript Programming Language I’ve shared on YUIBlog and in the YUI Theater two presentations created by Yahoo! JavaScript Architect Douglas Crockford (“Advanced JavaScript” and“An Inconvenient API: The Theory of the Dom”). Today I’m happy to announce that Douglas’s more foundational talk “The JavaScript Programming Language,” is publicly available. In this presentation, which is meant to be the beginning of the three-course sequence (followed by “Theory of the DOM” and then “Advanced JavaScript”), Douglas explores not only the language as it is today but also how the language came to be the way it is. It’s always worth pointing out that ideas and perspectives are Douglas’s own and that the many eggregious flaws in videographic craftsmanship are mine. Download slides (zipped PowerPoint file)

JavaScript Date Format Saturday, June 9th, 2007 • Related • Filed Under Update: The documentation below has been updated for the new Date Format 1.2. Get it now! Although JavaScript provides a bunch of methods for getting and setting parts of a date object, it lacks a simple way to format dates and times according to a user-specified mask. When choosing which special mask characters to use for my JavaScript date formatter, I looked at PHP's date function and ColdFusion's discrete dateFormat and timeFormat functions. With my date formatter, I've tried to take the best features from both, and add some sugar of my own. Before getting into further details, here are some examples of how this script can be used: var now = new Date(); now.format("m/dd/yy"); dateFormat(now, "dddd, mmmm dS, yyyy, h:MM:ss TT"); now.format("isoDateTime"); dateFormat.masks.hammerTime = 'HH:MM! Following are the special characters supported. And here are the named masks provided by default (you can easily change these or add your own):
