Statement


JavaScript statements make things happen. Every JavaScript program can be broken down into a series of statements, with each statement like an English sentence, except in JavaScript you end a sentence with a semicolon instead of a period. In fact, JavaScript is made up of sentences, phrases, and words. The sentences are statements, the phrases are expressions in which the elements of the action can be expressed and put together to make a statement, and the words are JavaScript operators, which are used to act upon the data passed to them.

CSS Menus

The code here creates a drop-down menu from HTML list elements using CSS. The code was written for and referenced to in Webmonkey’s Add CSS Drop-Down Menus tutorial.

Use Media RSS

With the explosive growth of podcasting, publishers are including more multimedia in their RSS feeds than ever. While the method of including media content in an RSS feed with enclosures is fairly well known, there are other methods available for including media content in RSS feeds, one of which is Media RSS.

Media RSS is an RSS module that was created to expand the way that multimedia content could be included in an RSS feed.

Originally authored by Yahoo! to improve media enclosures in RSS and also allow the submission of media content to its search engine via RSS, the development of Media RSS has since been opened up to the RSS community through the rss-media mailing list. Full disclosure: I’m also one of the people at Yahoo! who worked on the creation of Media RSS.

Make a Javascript Slideshow

JavaScript slide shows are great for a lot of reasons. You can use them to spice up photo albums, add a little pizzazz to your home page, or even show a story, stop-motion-animation style. And one of the beauties of JavaScript is its reusability:Once you create your script, building a new slide show is just a matter of copying the code and pointing it at a new image folder.

To get an idea of the magic I’m talking about here, take a look at the slide show I made of the pics from my friend Azure’s going away party. While Azure’s parting was sweet, sweet sorrow, my loss is your gain:The script I used to create this slide show is easy to learn and modify. Just you wait and see!

Yes, in the lessons that follow, I’ll show you how to build your very own slide show, then how to tweak it to your liking. (A hearty thanks goes out to Robert Bui – several parts of the JavaScript code I’m about to share are “inspired” by his script, which can be found at JavaScript.internet.com.)

How Many Users Are on Your Site Right Now

Hello, readers. You seem to be sending me a lot of e-mail lately. Fortunately, my spam sorter takes care of most of it, but a substantial stream of questions and comments keeps pouring in, inscrutable character sets and all. I wish they were all as eloquent as this one:

Paul Loved your articel! I have a few question. 1 How to setup? thanks.. derek meatburp

…but lately there have been more than a couple asking how to implement what’s apparently a very desirable feature — a little display of how many users are currently accessing a site. Of course there are dozens of pre-packaged scripts to do this, but, just because I love you all, let’s take a walk through a couple of ways to build this sort of feature from scratch. We’ll use PHP, the popular and friendly scripting language, for our examples.
