Enums in JavaScript

Category: Ajax, JavaScript

Matt Raible pointed me to Ditchnet.org which has some interesting JavaScript tips and tricks.

Graceful fallback from Ajaxian applications

Category: Ajax, JavaScript, Usability

One of the common arguments is whether or not your application “should just work” if the client doesn’t have JavaScript enabled (or an old version etc). Jep Castelein spoke about this recently. As always, when you are chosing technology you have decisions to make. One of them is the balance. How much time are you Read the rest…

Category: Ajax, Editorial, Java, JavaScript, Library

Having a lot of different implementations and innovations is certainly a good thing. However, many Java web developers are frustrated as hundreds or thousands have sprung up over time.

Ruby on Rails 0.11 includes native Ajax support

Category: Ajax, Ruby, Screencast

Rails 0.11.0 is out on the street and I’m especially proud of the Ajax support we’ve been able to include. Instead of trying to soften the blow of doing client-side Javascript libraries as many others are doing, we’ve gone ahead and more or less removed the need for hand-written client-side javascript entirely. This is done Read the rest…

It would make more sense to use: Web Remoting or, Remote Scripting Then, maybe a particular framework would be called Ajax. The JavaScript blog asked the question: “What Read the rest…
