The Basics of Object-Oriented JavaScript - Nettuts+ Over recent years, JavaScript has increasingly gained popularity, partly due to libraries that are developed to make JavaScript apps/effects easier to create for those who may not have fully grasped the core language yet. While in the past it was a common argument that JavaScript was a basic language and was very 'slap dash' with no real foundation; this is no longer the case, especially with the introduction of high scale web applications and 'adaptations' such as JSON (JavaScript Object Notation). JavaScript can have all that an Object-Orientated language has to offer, albeit with some extra effort outside of the scope of this article.

If I had a dime for every time I heard a web programmer apologize for the way his/her pages looked before revealing them, I certainly wouldn’t need to work anymore. As with color picking, I think that programmers tend to avoid doing certain things not because they are inherently bad at it, but because they don’t know how to proceed. They find themselves in an uncharted and foggy territory, without a map, no sense of direction, and with a limited ability to know if they’re getting any closer to where they want to be.
Also, when they talk to people that don’t share such problems and find it all too natural and obvious, it’s hard for the two to communicate in terms that make sense to a programmer. There is a general tendency to believe that programmers can’t style things because they have no style themselves. Don’t get me wrong: I don’t think anybody can design something truly beautiful, innovative, simple and that can resonate with a big percentage of the population. Em vs. 35 Designers x 5 Questions.

[2,547 diggs and counting.] The Point of CSS is to use clean, simple HTML in your page, then write CSS “rules” that style the objects on your page. The page stays clean and looks cool, and your HTML page works on both mobile devices and regular browsers.
That’s the point of CSS. But The Art of CSS is quickly and easily referring to the right objects in your page from your CSS rules. The act of matching CSS rules to HTML tags is like a conversation: both sides need to be clear and in sync with each other, or they’ll talk over each other and you’ll get a headache from all the yelling.General or Specific Matching: suppose you want to style an **<h1>** header in your page.

For those who are not AOL members, here are two screen shots of the interface. Both taken in MSIE, one with images enabled, the other with images disabled. (or "pictures" as they are called in the preferences): While their solution provides a uniform look across platforms (AOL is very interested in making sure things look "AOLish"), it doesn't do much for accessibility.
If images are disabled you've no way to know what the status of the checkbox is -- of course, if you cant even see the images you'll have no way of knowing what their status is either. This is an attempt to address these issues. How it Works The images you see above are inserted after each input element who's type attribute is "checkbox" for every form found in the document.

CheckBoxes - The Checkbox Object Similar to the Radio Object, the CheckBox object requires things to be set up in a particular manner. Again, to use this object you must have images for the two states of the checkbox: checkbox0.gif (false) checkbox1.gif (true) Which must be preloaded: preload('checkbox0','checkbox0.gif') preload('checkbox1','checkbox1.gif') This is the general format for the CheckBox Object: objectName = new CheckBox(layer,imgName,trueValue,falseValue,defaultToTrue) Where: layer - the layer the radio buttons are in imgName - the NAME in the IMG tag (see below) trueValue - the value when checked falseValue - the value when not checked defaultToTrue - (optional) use if the checkbox is initially true For my example, I have a checkbox for whether someone is a smoker or a non-smoker.

Smoker = new CheckBox('surveyDiv','smokerImg','smoker','non-smoker',true) Save DOM state using JSON. Brad Neuberg: Coding In Paradise: AJAX Tutorial: Saving Session. This is a mini-tutorial on saving state across page loads on the client side, without using cookies so as to save large amounts of data beyond cookies size limits. In AJAX, most of the action occurs inside a single web page.
When a page is loaded, a new instance of the JavaScript interpreter is started. When you leave a page, jumping to Google for example, all of your JavaScript objects are completely cleared away; you lose all of your state. If you then hit the back button to go back from Google to your original AJAX application, you will find that the page actually completely reloads, calling your onload listener, and that any JavaScript objects you stored anywhere are gone. This can be a pain. First, it's something that not all programmers are aware of, which can lead to errors, so it's important to know about.
Are there ways to save state on the client between page loads, akin to a user-level session? Method number one is to use an iframe in some special ways.
