Framework Disagreement: JQuery: (Mis)leading the Pack

Christian Decker wrote this just before lunchtime:
ustin Palmer has taken issue to some of the statements made by jQuery and writes JQuery: (Mis)leading the Pack as a retort of sorts to “Why JQuery’s Philosophy is Better”.

He makes some good points about:

  • DOM Insertion
  • Chainability
  • CSS Selectors/Xpath
  • Plugin Development
  • Automatic Looping
  • Ajax Updating
  • Adding a class to an element
  • Adding a class to a group of elements

A pretty honest and inclusive set of comments (not a “they suck, we rule” type post).

Really easy field validation with Prototype

Christian Decker wrote this around lunchtime:
I wanted a robust javascript validation library that was simple to implement and didn’t require me do any extra work other than creating the form. My favourite idea for a method of doing this is to utilise the field elements’ class attribute to indicate what sort of field it is and hence any validation requirements. There are a few javascript libraries that implement that idea like wForms, but, since I’m currently hell-bent on re-writing all my javascript using Prototype, I thought I’d see how difficult or easy it would be to roll my own. Turns out that this is just the sort of thing that is easy with Prototype.

qooxdoo 0.6 RC1 released

Christian Decker wrote this around lunchtime:
While reading the Ajaxian newsfeed I found a really nice screenshot about Qooxdoo 0.6 RC1 and I was impressed. Trying out the demos I decided that soon I would have to take a better look at this cute little library (or is it little at all?



Just take a look at it for yourself. It’s one of the nicest DOM-Manipulation libraries I’ve seen yet. If you need a full Windowing system it’s totally what you need :-)

Ajax based login using Acegi

Christian Decker wrote this around lunchtime:
Sanjiv Jivan just wrote a nice article on how to implement an Ajax enabled login system with Spring. I think it might be usefull ^^
Acegi is an extremely powerful Spring module for Authentication and Authorization and has almost become a defacto for web based applications built using Spring. Ajax based applications are getting hotter by the day and having a nice inplace Ajax based login page can improve coolness of your app and make it more Web 2.0′ish. However implementing an Ajax-Acegi based login does require a little extra work because based on the J2EE spec, when a user tries to login, they are redirected back to the login page if the credentials are invalid or redirected to the success page on successful authentication.

Read the full article here.

Ajax Charting System

Christian Decker wrote this just before lunchtime:

If you’ve been scouring the web looking for a pure Ajax charting solution, you might want to check out this offering from WebFX, a simple, free, easy to use charting system with multiple chart types included.

In web applications developed now days a lot of the logic that previously resided on the server side is now being implemented on the client side. This is especially true for information presentation, components such as trees and columnlist makes it possible for users to interact with the application, or web site if you wish, without contacting the server. However the ability to present data in a graphic rather than textual format has been quite limited, unless a plugin is used or an image is requested from the server.

That’s where this component comes in to place, it allows various forms of charts to be created, without any additional plugin, and without using images.

You can see an example of the charting in action in this demo showing line, bar, and combo graphs from generated data. There’s even documentation, usage examples and an API interface provided as well.
