Picture yourself on a beautiful beach on a warm day. The sounds of the waves is music to your hears. You’re on a comfortable chair with a laptop on your knees connected via an incredible WiFi. You’re using a brand new web2.0 application that must be the gratest web site on the web. Then, you […]

When I began with object-oriented javascript, I always saw a self here and there without fully understanding what it meant.
Self?
When you see self in some object-oriented javascript, it’s just mean that the developer is using a closure that will reference the current object via a variable named self. Because self is a variable, it could […]

Frank (of Ruby Fleebie) and I have been busy lately. We worked together on a project called Ecstatik!
What is Ecstatik!?
Ecstatik! is a project that caused Frank and I to be busy lately. But it’s not just that.
Ecstatik! is a digg-like for funny stuff. No more than that. We didn’t want to make the world a […]

Web2.0 came with the intensive use of the XMLHttpRequest object even if it was already in our browser before then. A lot of format were tried but JSON will be the winner overall.
What is JSON?
JSON is a format for communication between the server-side (PHP, ASP.NET, …) and the client-side (javascript). The magic of it is […]

This trick is not known by everyone though it is really simple.
The address bar
In the address bar, you simply write
javascript:/*some javascript code here*/;void(0);
As easy as that.
In fact, it’s the same thing as creating a link that executes some javascript code.
<a href=”javascript:alert(’Some code from a link’);”>Execute code from javascript</a>
The only thing I add is the void(0); […]

Javascript has a pretty basic Date object. It is cool but not as cool as in other languages. In fact, it is different but we like it anyway.
The primitive value
A date is nothing else than the number of millisecond since January 1, 1970 00:00:00. So now is 1 177 603 737 358.
When you create a […]

This one will be widely accepted. The problem with it is that it’s so obvious that the question is asked here and there.
Javascript is not secure
I repeat : javascript is not secure. Your code is readable and it can be modified by anyone. It is great when you want to do a bookmarklet. It is […]

I already said Do not use the style property on HTML objects and as I was thinking how bad the innerHTML property can be, I considered doing an article on that subject. The problem was that stones were thrown at me after the first “Do not” article. Now I fear that this one may be […]

I see a lot of person talking about how ajax is cool and it helps you doing things that you couldn’t do before it was “invented”. What most of these people don’t know is that most of the coolest features are not ajax. Ajax is just a way to communicate between a client and a […]

Since ajax, a lot of people have to create HTML on the fly depending on response of the request. One mistake that I see a lot is that people are using the style property of their HTML objects. Why shouldn’t I do it?
The style property has a precedence on every style
Because the style property is […]
