improve javascript prototypal inheritance
- by Julio
I'm using a classical javascript prototypal inheritance, like this: function Foo() {} Naknek.prototype = { //Do something }; var Foo = window.Foo = new Foo(); I want to know how I can improve this and why I can't use this model: var Foo = window.Foo = new function() { }; Foo.prototype = { //Do something }; Why this code doesn't work? In my head this is more logical than the classical prototypal inheritance.Read the article

Which JavaScript graphics library has the best performance?
- by DNS
I'm doing some research for a JavaScript project where the performance of drawing simple primitives (i.e. lines) is by far the top priority. The answers to this question provide a great list of JS graphics libraries. While I realize that the choice of browser has a greater impact than the library, I'd like to know whether there are any differences between them, before choosing one. Has anyone done a performance comparison between any of these?Read the article

my layout breaks in IE7 and javascript page reloads make the screen blink
- by chibineku
My layout breaks if I change the window size in IE7/AOL, so I added a simple javascript function that fires on window.onresize, but no matter how I change the location I get problems. It was suggested I post a link and here it is: link text I already use PHP to detect browser and include an IE7-only inline stylesheet (and for mobile browsers), and my page looks nearly identical to the way it does in FF, Opera, Chrome, Safari and IE8, but when I change the window size, some things go wonky, and come back into line if you refresh. Any advice is welcome :)Read the article
