JavaScript and HTML Tricks

Here are some of my favorite JavaScript and HTML tricks. There are a wide variety of options: from storing and using hidden data to making HTML forms and lists look great. Each topic has a brief introduction showing you how it will improve your Web site. Then I'll go into each technique in detail.

Protecting against evil code fragments with HTML Purifier

HTML Purifier is a project that helps you ensure that HTML is valid and does not contain cross-site scripting attempts or other nasty attacks. With HTML Purifier you can allow users to post HTML content without letting them insert nasty code that will run in the browser of anyone viewing that HTML. An assortment of plugins let you use HTML Purifier with CodeIgniter, Drupal, MODx, Phorum, Joomla!, and WordPress. To get an idea of the cleanups that HTML Purifier can perform, head over to the demo page.

Firefox Gets Massive JavaScript Performance Boost

monkeymonkey writes "Mozilla has integrated tracing optimization into SpiderMonkey, the JavaScript interpreter in Firefox. This improvement has boosted JavaScript performance by a factor of 20 to 40 in certain contexts. Ars Technica interviewed Mozilla CTO Brendan Eich (the original creator of JavaScript) and Mozilla's vice president of engineering, Mike Shaver. They say that tracing optimization will 'take JavaScript performance into the next tier' and 'get people thinking about JavaScript as a more general-purpose language.' The eventual goal is to make JavaScript run as fast as C code. Ars reports: 'Mozilla is leveraging an impressive new optimization technique to bring a big performance boost to the Firefox JavaScript engine. ...They aim to improve execution speed so that it is comparable to that of native code.

Cocoa-Like JavaScript Framework Announced

TwilightSentry writes "Ars Technica reports that a group of developers has created an Objective-C-like extension to JavaScript along with a class library mirroring Cocoa. They've used these to release an impressive demo app called 280 Slides. The article notes, 'Whereas SproutCore seeks to "embrace the platform" by giving a Cocoa-like development model for developers already using HTML, CSS, and JavaScript to make a web app, Cappuccino and Objective-J take an entirely different approach. "Since Cappuccino runs entirely on the client, at run time, we're never actually generating HTML or CSS," says Boucher. "When you build an application in Cappuccino, you don't need to ever deal with HTML or CSS. All of your interface is designed in Objective-J and Cappuccino.

Firefox Javascript Performance To Get A Shot In The Arm

If you are anything like me, then websites which make heavy use of Javascript may get slightly frustrating at times, slowing down pages that would otherwise be responsive. The good news is that Mozilla has been working on some new optimization to greatly increase the performance of Firefox's Javascript engine. The optimization tactic called 'tracing' has seen performance increases of between 20 and 40 fold in some cases, and believe the work being put down will pave the way for developers to use Javascript for writing full applications. It should also increase Firefox performance in general, as a number of components and extensions are coded in Javascript. The code should see inclusion in the next update to Firefox (3.1), and it is worth noting that Apple have also been implementing performance improvements, which are due to find their wa

Is knowing HTML important for Web designers?

I was reading a blog post on Disassociated.com and they said that they've worked with art directors on a design team who don't even know what HTML stands for - let alone how to do it. On the other hand, Tony Patton on Builder.au says that it's not possible. He points out that HTML is very easy to learn, and I completely agree. While I do think that it's possible to create nice looking pages without knowing HTML, if you want to be a truly proficient Web designer and developer, then you need to learn HTML and learn CSS.

Performance Optimizations for High Speed JavaScript

In this article, we look at how important JavaScript optimizations are analyzed. These will be explained, including using local function variables, avoiding references to objects or object properties, avoiding adding short strings to long strings, and finally, using buffering to process data in optimal sizes. These general-purpose JavaScript optimization techniques are designed for JavaScript on all browsers. Detailed graphs of all the performance results are given after each optimization. You will be amazed at the incredible speed improvements in JavaScript!

JavaScript: The Good Parts

Anita Kuno writes "JavaScript: The Good Parts is about the good parts of JavaScript and how to use them. This book takes a realistic look at the strengths and weaknesses of JavaScript and tells you how to use it to its best advantage. The code samples deal with the language and its merits — creating web pages is not discussed. How to understand the language, to execute the operations you want, is the focus of the book, not how to make rounded corners. The author, Douglas Crockford says, 'My microwave oven has tons of features, but the only ones I use are cook and the clock. And setting the clock is a struggle. We cope with the complexity of feature-driven design by finding and sticking with the good parts.'" Keep reading for the rest of Anita's review.

Thwarting New JavaScript Malware Obfuscation

I Don't Believe in Imaginary Property writes "Malware writers have been obfuscating their JavaScript exploit code for a long time now and SANS is reporting that they've come up with some new tricks. While early obfuscations were easy enough to undo by changing eval() to alert(), they soon shifted to clever use of arguments.callee() in a simple cipher to block it. Worse, now they're using document.referrer, document.location, and location.href to make site-specific versions, too. But SANS managed to stop all that with an 8-line patch to SpiderMonkey that prints out any arguments to eval() before executing them. It seems that malware writers still haven't internalized the lesson of DRM — if my computer can access something in plaintext, I can too.

Visual Studio 2008 simplifies JavaScript debugging

One of the more cumbersome development tasks is debugging client-side JavaScript code. Tools such as Firebug are helpful, but in the case of Firebug, you're forced to use Firefox. Thankfully, Visual Studio 2008 provides a robust and developer-friendly environment for debugging JavaScript.
