JQuery Parsed Ajax Errors

A very cool code fragment I ran into while looking for something else — funny how that happens.

jQuery Deferreds and the jQuery Promise Method

JQXHR AND THE PROMISE INTERFACE

1. $.ajaxPrefilter(function( options, originalOptions, jqXHR ) {
2.   if ( options.parseError ) {
3.     jqXHR.pipe( null, function( jqXHR, statusText, errorMsg ) {
4.         var parsed = $.parseJSON( jqXHR.responseText );
5.         return $.Deferred().rejectWith( this, [ jqXHR, statusText, parsed ] );
6.     }).promise( jqXHR );
7.     jqXHR.success = jqXHR.done;
8.     jqXHR.error = jqXHR.fail;
9.   }
10. });

JQuery 1.7 Callbacks

Callbacks

The general idea behind pub/sub (the Observer pattern) is the promotion of loose coupling in applications. Rather than single objects calling on the methods of other objects, an object instead subscribes to a specific task or activity of another object and is notified when it occurs.

ParseResponse({“title” : “Get Your JSON Response Anywhere”})

From Programmable Web

JSONP simply wraps the response in a function call named by the developer. The P stands for “padding,” where the provider needs only pad the results with a bit more information. Supporting JSONP is a cinch.

JQuery Plugin Mechanism

Extending the Library

Another excellent article on extending JQuery.

The jQuery library is centered on a root object, which exposes a number of methods. After doing whatever tasks it was called to do, each method just returns the instance of its parent object. In this way, a new call to another method can be arranged on the same expression.

(function( $ ){
 $.fn.yourPluginName = function() {
 // your code here
 };
})(jQuery)

Elements of Design?

An interesting take on what a design is, rather than how to accomplish one.

By exploring these elements individually—and by thinking about design as not just a noun (the design) but also a verb (to design)—we can approach the abstract question of “What is design?” in a productive way.

Using the JQuery Cache

Using Client Side Storage

Session duration storage management made not a total pain in the browser.

The jQuery library offers ..  a simple but quite effective API to store data in the browser’s memory for the duration of a session.

Agility at the Speed of Kwality

The Agile UnManefesto

Dr. Dobb article on Agile umpteen years later. The Agile process is popular but sometimes just doesn’t turn out so well.  Process in general improves the end product, thats the idea anyway.

My own feeling is that Agile tries to capture how a high quality engineer works. Unfortunately, it takes a high quality engineer. Agile really depends on a great team leader and a good team to be successful, more so than other processes.

From the article, link below.

First, let’s jump to what most people will perceive to be the end results. As a group, we agreed on the following four belief statements:

1. Demand technical excellence
2. Promote individual change and lead organizational change
3. Organize knowledge and improve education
4. Maximize value creation across the entire process

Let’s dive down into what these belief statements imply. The first statement, demand technical excellence, is a reflection both of the general values of the working group and also our frustration with what we’re seeing in practice — or more accurately, not seeing in practice.

Agile development explained

HTML5, Promise, Hype, Whatever

Syntax and Semantics Are Important

An interesting article on marketing versus reality on HTML5.

It has been my opinion that HTML, the language written over 30 years by committee and pushy individuals, is less than perfect.

I’d rather see XML period. A markup language in XML would be semantically correct, and syntactically consistent.

Until then, market me this 🙂

JQuery Event Handling

De-complicating Browser Event Handling

JQuery simplifies event handling across browsers.

In jQuery, you define an event handler by simply passing the code you want to execute to a function that identifies the particular event.  There are several ready-made functions for most common events such as click, blur, hover, change, dblclick, focus, select (text selection), ready, scroll, and resize , plus multiple events for keyboard and mouse actions.
